    Description: Antarctic coastal waters are home to several established or proposed Marine Protected Areas (MPAs) supporting exceptional biodiversity. Despite being threatened by anthropogenic climate change, uncertainties remain surrounding the future ocean acidification (OA) of these waters. Here we present 21st-century projections of OA in Antarctic MPAs under four emission scenarios using a high-resolution ocean–sea ice–biogeochemistry model with realistic ice-shelf geometry. By 2100, we project pH declines of up to 0.36 (total scale) for the top 200 m. Vigorous vertical mixing of anthropogenic carbon produces severe OA throughout the water column in coastal waters of proposed and existing MPAs. Consequently, end-of-century aragonite undersaturation is ubiquitous under the three highest emission scenarios. Given the cumulative threat to marine ecosystems by environmental change and activities such as fishing, our findings call for strong emission-mitigation efforts and further management strategies to reduce pressures on ecosystems, such as the continuation and expansion of Antarctic MPAs.

    Description: Um das Jahr 1540 erließen die Herren zu Franckenstein und die Herren von Heusenstamm eine Bergordnung für die Bergwerke in Espa im Taunus. Als Vorlage für diese Bergordnung diente eine Abschrift der Bergordnung der Grafen von Hohnstein vom 3. Februar 1528 für die Bergwerke in der Grafschaft Lauterberg. Es wurden aber nicht alle Paragrafen übernommen. Es fehlen eine Abschlusserklärung mit den Anwendungsbestimmungen sowie ein Datum zum Erlass dieser Bergordnung. Wahrscheinlich handelt es sich bei dieser Bergordnung um einen unveröffentlichten Entwurf. Eine weitere Bergordnung für dieses Gebiet ist aber nicht bekannt.

    Description: The historical archive of global ocean subsurface temperature contains a large proportion of poorly quality-controlled as well as biased data. As a result, efforts to analyze past ocean change and variability are confounded, as is the use of ocean data assimilation systems. Currently many data centers perform automated ‘quick and dirty QC’ – redoing the same job poorly many times around the world. There have been no previous efforts to form a clean and definitive and very much needed historical archive. No single group has the manpower and resources to do the job properly – thus international cooperation is needed. The IQuOD 6thh Workshop goals are to: 1. Obtain agreement for the AutoQC process for application to the next product version. 2. Plan for the next IQuOD product: what will it consist of and what do we need to complete to get to the next release.

    Description: Under Indian legislation, i.e. various state Marine Fishing (Regulation) Act (MFRAs), small-scale traditional fishers are granted exclusive rights to near-shore marine waters, ostensibly to protect their rights and livelihoods. However, failures in implementation, management and monitoring of these exclusive small-scale artisanal fishing zones (SFZs), has hampered the holistic actualization of these protections. Establishing secure tenure rights to marine and coastal spaces and resources can be considered sine qua non for equity and justice. It is essential to rejuvenate existing mechanisms and bolster them through the principles of human rights and the SSF Guidelines to protect and support small-scale fisheries in our future.

    Description: The incessant noise over ‘Blue Economy’ and ‘Blue Growth’ leaves artisanal and small-scale fishers dazed and confused. This report works through that confusion. It draws on scholarship from the trenches and the research centres across ten Latin American countries. From extensive interviews, policy reviews, analyses of finances and online datasets. In granular detail, it examines how Blue Growth affects artisanal fishers and their need for equity and justice. Through the baffling shades of blue—conflicts, priorities, the politics of managing our coasts and seas—this report finds clear light. It lays down the agenda for fishworkers and organizations working for them.

    Description: High-latitude ionospheric plasma constitutes a very complex environment, which is characterized by turbulent dynamics in the presence of different ion species. The turbulent plasma motion produces statistical features of both electromagnetic and velocity fields, which have been broadly studied over the years. In this work, we use electric field high-resolution observations provided by the China-Seismo Electromagnetic Satellite-01 in order to investigate the properties of plasma turbulence within the Earth’s polar cap. We adopt a model of turbulence in which the fluctuations of the electric field are assimilated to a stochastic process evolving throughout the scales, and we show that such a process (i) satisfies the Markov condition (ii) can be modeled as a continuous diffusion process. These observations enable us to use a Fokker–Planck equation to model the changes in the statistics of turbulent fluctuations throughout the scales. In this context, we discuss the advantages and limitations of the proposed approach in modeling plasma electric field fluctuations.

    Description: The study investigates the influence of interplanetary magnetic field (IMF) orientation on loss of lock (LoL) events in GPS signals. We analyzed LoLs recorded on two Swarm satellites between July 2014 and December 2021, examining how the signs of the IMF $B_x$, $B_y$, and $B_z$ components affect the distribution of events at high latitudes. Our results reveal an asymmetric distribution of LoL events over 75° magnetic latitude. In the Northern hemisphere, more events occur in the post-noon sector with negative IMF $B_y$, and in the pre-noon sector with positive IMF $B_y$. Conversely, in the Southern hemisphere, pre-noon events increase with negative IMF $B_y$, while post-noon events increase with positive IMF $B_y$. At lower latitudes (50°-75°), IMF $B_y$ does not significantly affect the event distribution, which mainly concentrates in the night sector for both hemispheres. Additionally, we found a connection between IMF $B_y$ and $B_x$, primarily due to the IMF spiral structure. Finally, we discuss our findings in the context of the SuperDARN data-driven model of ionospheric convection patterns, which shows that LoL events frequently cluster in the cusp region, as well as the area where the two convection cells separate.

    Description: Previous studies have shown that solar wind, a plasma medium with turbulent dynamics, exhibits anomalous scaling features, i.e., intermittency, in the inertial domain. This intermittent nature has primarily been investigated through the study of the scaling features of the structure functions of single quantities. We use a novel approach based on joint multifractal analysis in this study to simultaneously investigate the scaling characteristics of both the magnetic field and the plasma velocity in solar wind turbulence. Specifically, we focus on the joint multifractal behavior of magnetic and velocity field fluctuations in both fast and slow solar wind streams observed by the ESA-Ulysses satellite, with the goal of identifying any differences in their joint multifractal characteristics.

    Description: “Pressure and time.” A momentous quote in a compelling movie from a few decades ago interestingly pointed at some of the ingredients that contributed to shaping the Earth. The movie set off from how to seep through masses that appeared just too vast to be shakable or vulnerable – if not by deciphering their inner core. The planetary size and time frame of the Earth may have elicited a perception of a durable, unbuckling living environment – just because “pressure and time” to really affect it would have been out of human reach – supposedly. However, the Earth and environmental sciences have long striven to alert contemporary societies that this is just not the case, as humans have been well exerting scattered yet ubiquitous, planetary-scale pressure over a relatively brief time – with consequential, durable effects. Rising global population, long-term migration shifts of continental extents – due to risks, climate, resources – and unpredicted factors – from vulnerabilities to instabilities – pressure on the environment (natural and built) in unprecedented scale throughout human history. The Earth sciences were born out of deciphering ancient life forms teeming in an aboriginal environment, unfolding on a planet that could be explained only by looking at the Solar system – and at the inception of the Universe. Cross-disciplinary by nature, the Earth and environmental sciences offer crucial tools to gauge location, economic turnout, and societal costs of those very resources and fragilities. They also are pivotal co-actors of intellectual stewardship bridging the gulf with sister disciplines well beyond the remits of the physical sciences. From economics to philosophy, and from history to literature, multiple, diverse and concurring threats call for resourceful, multi-faceted mind- and skill-sets where no single hazard may be really treated apart – not on societal terms. Adapting a famous statement from the 20th century, evolution in a time of poly-crises, multiple hazards, and accrued vulnerabilities is not going to be a dinner party for contemporary societies – especially as they dwell a world perceived as increasingly richer in risks and poorer in resources, with a growing population and across instabilities. Human Earth sciences offer a bridge towards our collective future – as societies, continents, planets.

    Description: Back-arc basins (BABs) are associated with plate margins where crustal shortening, seafloor spreading, and volcanism coexist. The Vavilov basin (Tyrrhenian Sea) is a Pliocene BAB associated with the Apennine-Tyrrhenian Sea subduction system and characterized by mantle exhumation. The NNE-SSW elongated Vavilov seamount represents the easternmost and younger spreading ridge of the Vavilov basin. Here we present results of a morphological and magnetic study of the Vavilov seamount. Our results show that the seamount represents the last stage of the eastward asymmetric opening of the BAB. Its plumbing system consists of a dike swarm emplaced during the reversed Matuyama epoch and a younger shallow reservoir feeding the central and eastern sectors during the normal Brunhes epoch. This evolution is associated with the progressive loading of the edifice due to lava flow emplacement. The asymmetry of the seamount mirrors the asymmetric opening of the Vavilov back-arc basin.

    Description: Several empirical formulations used over time to estimate the fundamental ionospheric parameter hmF2 have been compared in this study. These are the first formulation proposed by Shimazaki (1955) (SHI-1955) as a function of the propagation parameter M(3000)F2, the more accurate BSE-1979 formula proposed by Bilitza et al. (1979) and firstly adopted by the International Reference Ionosphere (IRI) model, and the newest Altadill-Magdaleno-Torta-Blanch (AMTB-2013) (Altadill et al., 2013) and SHU-2015 (Shubin, 2015) models, obtained with a different approach with no explicit dependence on any ionospheric parameter and added as alternative options in the IRI-2016. The evaluation of the accuracy of the available formulation is performed by comparing the modeled values of hmF2 with those simultaneously obtained with independent measurements from the Incoherent Scatter Radar (ISR) installed at the Millstone Hill ionospheric station. The database considered consists of 3626 measurements, thus allowing the evaluation of the results for different heliogeophysical conditions. SHI-1955 and BSE-1979 formulations are evaluated also using input data manually scaled from ionograms recorded at the same location, with the aim of evaluating their accuracy when updated with validated data rather than modeled ones. The SHU-2015 is confirmed the best option in any condition, while AMTB-2013 turns out to perform poorly during night, when SHI-1955 and BSE-1979 fed by validated data can be used for trend analyses due to the high correlation with ISR data. Despite this, BSE-1979 performs better with modeled parameters as input, in terms of RMSE and mean deviation from ISR data. The use of SHI-1955 with CCIR-modeled M(3000)F2 is discouraged under daytime conditions even for long trend analyses.

    Description: The Arctic climate is influenced by the interaction of shortwave (SW) and longwave (LW) radiation with the atmosphere and the surface. The comprehensive evolution of the Surface Radiative Fluxes (SRF) on different time scales is of paramount importance to understanding the complex mechanisms governing the Arctic climate. However, only a few sites located in the Arctic region provide long-term time series of SRF allowing for capturing the seasonality of atmospheric and surface parameters and carrying out validation of satellite products and/or reanalyses. This paper presents the daily and monthly SRF record collected at the Thule High Arctic Atmospheric Observatory (THAAO, 76.5° N, 68.8° W), in North-Western Greenland. The downwelling components of the SW (DSI) and the LW (DLI) irradiances have been measured at THAAO since 2009, while the collection of the upwelling SW (USI) and LW (ULI) irradiance was started in 2016, together with additional measurements, such as e.g., meteorological parameters and column water vapour. The datasets of DSI (Meloni et al., 2022a; https://doi.org/10.13127/thaao/dsi), USI (Meloni et al., 2022b; https://doi.org/10.13127/thaao/usi), DLI (Meloni et al., 2022c; https://doi.org/10.13127/thaao/dli), ULI (Meloni et al., 2022d; https://doi.org/10.13127/thaao/uli), and near surface air temperature (Muscari et al., 2018; https://doi.org/10.13127/thaao/met), can be accessed through the THAAO web site (https://www.thuleatmos-it.it/data). DSI is absent (solar zenith angle≥90°) from 29 October to 13 February, assuming maxima in June (monthly mean of 277.0 Wm-2), when it is about half of the total incoming irradiance. The USI maximum occurs in May (132.4 Wm-2) due to the combination of moderately high DSI values and high albedo. The shortwave surface albedo (A) assumes an average of 0.16 during summer, when the surface is free of snow. Differently, during months of snow-covered surface, when solar radiation allows estimating A, its values are greater than 0.6. A large interannual variability is observed in May and September, months characterized by rapidly changing surface conditions, which appear to be linked with air temperature anomalies. DLI and ULI maxima occur in July and August, and minima in February and March. ULI is always larger than DLI and shows a wider annual cycle. ULI is well described by a fourth-order polynomial fit to the air temperature (R2〉0.99 for monthly data and R2〉0.97 for daily data). The surface radiation budget (SRB) is positive from April to August, when absorption of solar radiation exceeds the infrared net cooling, with a maximum value of 153.2 Wm-2 in June. From November to February, during the polar night, the LW net flux varies between -34.5 and -43.0 Wm-2. In March and September, the negative LW net flux overcomes the positive SW contribution, producing a negative SRB. THAAO measurements show clear evidence of the influence of several regional weather/climate events, which appear strongly linked with SRF anomalies. These anomalies are found for example during summer 2012, when a large ice melting event took place over Greenland, and during winter 2019–2020, extraordinarily cold in the Arctic region.

    Description: In this paper, we provide a characterisation of the ionosphere from April 2018 to September 2022 for 48 investigated months. We used the data of the China Seismo Electromagnetic Satellite (CSES-01), which is a sun-synchronous satellite with five days of revisit time and fixed local time of about 2 a.m. and 2 p.m. The unique orbit of CSES-01 permitted us to produce a monthly background of the ionosphere for night- and daytime with median values acquired during geomagnetic quiet time in equatorial and mid-latitude regions (i.e., between 50° S and 50° N of geographical latitude). We compared the obtained CSES-01 monthly median values with the solar activity in terms of sunspot numbers, and we found a high correlation of 0.89 for nighttime and 0.85 for daytime between the mean sunspot number and the maximum of the characterised CSES-01 Ne map values. In addition, we extracted all the anomalous positive increases in CSES-01 electron density and compared them with the Worldwide M5.5+ shallow earthquakes. We tested two different definitions of anomaly based on median and interquartile range or (mild) outliers. We tried two relationships between anomalies inside Dobrovolsky’s area before the earthquake and the magnitude of the same seismic events: one which considers distance in space and time and a second which only uses the anticipation time of the anomaly before the earthquake. Using both anomaly definitions, we searched the best coefficients for these two laws for mid-latitude and equational regions. We found that the best coefficients are independent of the anomaly definition, but better accuracy (greater than 80%) is obtained for the outlier definition. Finally, using receiving operating characteristic (ROC) curves, we show that CSES-01 increases seem statistically correlated to the incoming seismic activity.

    Description: Temperature is a major source of inaccuracy in high-sensitivity accelerometers and gravimeters. Active thermal control systems require power and may not be ideal in some contexts such as airborne or spaceborne applications. We propose a solution that relies on multiple thermometers placed within the accelerometer to measure temperature and thermal gradient variations. Machine Learning algorithms are used to relate the temperatures to their effect on the accelerometer readings. However, obtaining labeled data for training these algorithms can be difficult. Therefore, we also developed a training platform capable of replicating temperature variations in a laboratory setting. Our experiments revealed that thermal gradients had a significant effect on accelerometer readings, emphasizing the importance of multiple thermometers. The proposed method was experimentally tested and revealed a great potential to be extended to other sources of inaccuracy, such as rotations, as well as to other types of measuring systems, such as magnetometers or gyroscopes.

    Description: This study is focused on fluids characterization and circulations through the crust of the Irpinia region, an active seismic zone in Southern Italy, that has experienced several high-magnitude earthquakes, including a catastrophic one in 1980 (M = 6.9 Ms). Using isotopic geochemistry and the carbon‑helium system in free and dissolved volatiles in water, this study aims to explore the processes at depth that can alter pristine chemistry of these natural fluids. Gas-rock-water interactions and their impact on CO2 emissions and isotopic composition are evaluated using a multidisciplinary model that integrates geochemistry and regional geological data. By analyzing the He isotopic signature in the natural fluids, the release of mantle-derived He on a regional scale in Southern Italy is verified, along with significant emissions of deep-sourced CO2. The proposed model, supported by geological and geophysical constraints, is based on the interactions between gas, rock, and water within the crust and the degassing of deep-sourced CO2. Furthermore, this study reveals that the Total Dissolved Inorganic Carbon (TDIC) in cold waters results from mixing between a shallow and a deeper carbon endmember that is equilibrated with carbonate lithology. In addition, the geochemical signature of TDIC in thermal carbon-rich water is explained by supplementary secondary processes, including equilibrium fractionation between solid, gas, and aqueous phases, as well as sinks such as mineral precipitation and CO2 degassing. These findings have important implications for developing effective monitoring strategies for crustal fluids in different geological contexts and highlight the critical need to understand gas-water-rock interaction processes that control fluid chemistry at depths that can affect the assessment of the CO2 flux in atmosphere. Finally, this study highlights that the emissions of natural CO2 from the seismically active Irpinia area are up to 4.08·10+9 mol·y-1, which amounts is in the range of worldwide volcanic systems.

    Description: The ionosphere has distinctive characteristics under different solar and geomagnetic conditions, as well as throughout the seasons, and has a direct impact on our technological life in terms of radio communication and satellite navigation systems. In the pursuit of developing highly accurate ionospheric models and/or improving existing ones, understanding the various physical mechanisms that influence electron density dynamics is critical. In this study, we apply the Multivariate Empirical Mode Decomposition (MEMD) method to the electron density distribution in the mid-to-high latitude (above 50 ° magnetic latitude) regions in order to identify the dominant scales at which these mechanisms operate. The data were collected by the Swarm mission in the Northern Hemisphere. MEMD allows us to separate the main intrinsic modes and assess their relative contributions to the original one, thereby identifying the most important modes and the spatial scales at which they exert influence. Our study spanned the period from 1 January 2016 to 31 December 2021, which was characterized by low solar activity levels. This choice allowed for a more focused investigation of other variables influencing electron density distribution under similar solar activity conditions. We specifically examined the variations of the resulting modes in relation to different seasons and geomagnetic activity conditions, providing valuable insights into the complex behavior of the ionosphere in response to various external factors.

    Description: Ionospheric irregularities are plasma density variations that occur at various altitudes and latitudes and whose size ranges from a few meters to a few hundred kilometers. They can have a negative impact on the Global Navigation Satellite Systems (GNSS), on their positioning accuracy and even cause a signal loss of lock (LoL), a phenomenon for which GNSS receivers can no longer track the satellites' signal. Nowadays, the study of plasma density irregularities is important because many of the crucial infrastructures of our society rely on the efficient operation of these positioning systems. It was recently discovered that, of all possible ionospheric plasma density fluctuations, those in a turbulent state and characterized by extremely high values of the Rate Of change of the electron Density Index appear to be associated with the occurrence of LoL events. The spatial distributions of this class of fluctuations at mid and high latitudes are reconstructed for the first time using data collected on Swarm satellites between July 15th, 2014 and December 31st, 2021, emphasizing their dependence on solar activity, geomagnetic conditions, and season. The results unequivocally show that the identified class of plasma fluctuations exhibits spatio-temporal behaviours similar to those of LoL events.

    Description: A new method to define a background for the ionospheric electron density (Ne) is proposed, making use of mid-latitude measurements under different solar conditions from the Langmuir Probes onboard CHAMP and three identical Swarm satellites. In particular, CHAMP measurements during the years 2004 and 2009, and Swarm observations during 2016 and 2017 have been considered in the 15°-wide latitudinal belt from 35°N to 50°N, and from 0° to 360° in longitude. CHAMP/Swarm in-situ Ne measurements have been then used to check and compare this new defined background with the one computed directly from IRI-2016 Ne output at satellite altitude. The distributions of the relative deviations between the two backgrounds, and of positive and negative anomalies (i.e., Ne variations from each background greater than 30%) with respect to the geomagnetic activity levels have been evaluated under each investigated condition, namely year/satellite, season, night-time or noon hours. Results of this comparison highlight a general overestimation of Ne from IRI during noon hours, while a better agreement between the two backgrounds is found during night-time. However, an underestimation of IRI with respect to Swarm-derived background is found for 2017 data. Finally, the analysis of 2004 plasma data suggests that the IRI-2016 model can be used as a background during periods characterized by high levels of geomagnetic activity. Due to the difficulties to construct a background for satellite data, the proposed method can be considered an useful tool for analyses of electron density variations at the heights of the satellites in Low Earth Orbits (LEO).

    Description: Ground-based high resolution observations of downward longwave irradiance (DLI), surface air temperature, water vapour surface partial pressure and column amount, zenith sky infrared (IR) radiance in the atmospheric window, and all-sky camera images are regularly obtained at the Thule High Arctic Atmospheric Observatory (THAAO, 76.5° N, 68.8° W), North-West Greenland. The datasets for the years 2017 and 2018 have been used to assess the performance of different empirical formulas to infer clear sky DLI. An algorithm to identify clear sky observations has been developed, based on value, variability, and persistence of zenith sky IR radiance. Seventeen different formulas to estimate DLI have been tested against the THAAO dataset, using the originally determined coefficients. The formulas which combine information on total column water vapour and surface air temperature appear to perform better than others, with a mean bias with respect to the measured DLI smaller than 1 W/m2 and a root mean squared error (RMSE) around 6 W/m2. Some formulas, specifically developed for the Arctic, are found to produce poor statistical results; this is attributed partly to limitations in the originally used dataset, which does not cover a whole year, or is relative to very specific conditions (i.e., the ice sheet). The bias displays a significant improvement when the coefficients of the different formulas are calculated using the THAAO dataset. The presence of two full years of data allows the investigation of the inter-annual variability, and the use of different years for the determination of the coefficients and the evaluation of results. The smallest values of the bias and RMSE reach 0.1 W/m2 and 5 W/m2, respectively. Overall, best results are found for formulas which use both surface parameters and total water vapour column, and have been developed from global datasets. Conversely, formulas which express the atmospheric emissivity as a linear function of the logarithm of the column integrated water vapour appear to poorly reproduce the observations at THAAO.

    Description: The Campo Felice basin, in the central Apennines seismic belt (Italy), developed in the hangingwall of a 30 km-long system of NW-trending normal faults with Holocene paleoseismic activity and potential sources of M 6–7 earthquakes. We provide the first subsurface images of a key portion of the basin bounded by the Mt. Cefalone fault along two intersecting profiles trending NNE-SSW (CF-Dip, 1195 m-long) and WNW-ESE (CF-Strike, 1315-m long). We combined high-resolution depth-migrated reflection sections with P-wave velocity and electrical resistivity tomography models. CF-Dip profile displays a wedge-like syn-tectonic sedimentary sequence of alluvial and glacial deposits with Vp ∼ 2500–3000 m/s and resistivity 〉 500 Ωm in the hangingwall of Mt. Cefalone fault, overlying a high-Vp (〉4000 m/s) limestone bedrock ∼ 300 m deep. The whole sequence displays reflectors truncated by the Mt. Cefalone fault zone and subsidiary antithetic faults. CF-Strike profile, tied to three 80–110 m-deep boreholes, shows a thick fluvio-lacustrine sequence with low-Vp (〈2000 m/s) and low resistivity (〈100 Ωm), and a bedrock that deepens to the southeast (〉450 m). Single-station ambient noise measurements display Horizontal to Vertical Spectral Ratios with peaks at ∼1 Hz, decreasing to ∼0.8 Hz to the southeast in agreement with the bedrock deepening indicated by seismic profiling. According to our results, the Campo Felice basin is a deep asymmetric half-graben controlled by faulting whose activity likely started before the Middle Pleistocene. Our minimum displacement estimate accrued in the past 0.5 Ma by the Mt. Cefalone fault is in the range of ∼100–250 m.

    Description: Calving of iceberg at ice shelves and floating glacier tongues is a poorly understood process, hence a physically motivated calving law is not yet existing. The demands on developing appropriate models for calving is large, as calving rates are needed for large scale ice sheet models that simulate the evolution of ice sheets. Here, we present a new approach for simulating fracture in ice. Our model is based on a finite strain theory for a viscoelastic Maxwell material, as the large simulation time leads to high strains. The fracturing process is simulated using a fracture phase field model that takes into account the elastic strain energy. We conduct simulations for a typical calving front geometry, with ice rises governing the formation of cracks. To represent the stress state adequately, we first conduct a spin-up to allow the viscous contribution to develop before the fracture phase field is computed. The analysis comprises the assessment of the crack path in comparison to observations, the influence of the spin-up, as well as elastic versus viscous strain contributions based on Hencky strain. Additionally, an estimate of released energy based on high resolution optical imagery of a Greenlandic calving front is presented.

    Description: The blue jack mackerel, Trachuruspicturatus, is a commercially important resource in the Mediterranean Sea and the North-East Atlantic. The main aim of this work was to assess the infection levels and diversity of the ectoparasites of the blue jack mackerel.Over a one-year period, between March 2017 and February 2018, 126 specimens of T. picturatuswere collected seasonally from the Bizerte coast (Tunisia). The ectoparasite fauna of the examined host was composed ofthe two monogenean species, Pseudaxinetrachuriand Gastrocotyletrachuriand a copepod species,Peniculusfistula fistula. This is the first record of thiscopepod parasite inTunisia. The analysis revealed that the infection levels fluctuated throughout the year. Both monogeneans (P. trachuriand G. trachuri) had high prevalences during the warm season (P%=87.1, P%= 32.3, respectively). Additionally, P. trachurishowed some seasonal variations in mean abundance and mean intensity between summer and the other seasons. Furthermore, there was a highly significant variation in the mean abundance of G. trachuribetween the summer and autumn-winter seasons. The resultsof the current study may be explained by the seasonal variations in environmental conditions, the life cycles of the hosts and parasites, the feeding and migratory patterns of the hosts, the chemicals released by the hosts, and the interspecific competition between the two monogenean species.

    Description: Biological invasions are widely acknowledged as a serious threat to biodiversity, but the role of parasites in marine ecosystem processes is still poorly understood. The so-called Lessepsian migration, or invasions through the Suez Canal from the Red Sea to the Mediterranean Sea, also fits this description. Here, we studied the parasitofauna of Fistularia commersonii collected from the Gulf of Gabès of Tunisia. 43 individuals of F. commersonii were sampled from the Gulf of Gabès. Parasite richness, prevalence and intensity were investigated, Additionally, we reviewed the literature to identify native and invasive parasite species recorded. Our results suggest the co-introduction of nine parasite species that are assumed to be originate from the Red Sea. In addition, we found that the invasive fish has acquired nineteen parasite species that are native from the Mediterranean Sea. The Lessepsian migrant may potentially change the dynamics of native and invasive parasite-host interactions through parasite co-introduction and parasite acquisition, according to these results. The higher F. commersonii infection rates in the area that has been invaded are also consistent with the predictions made by the "Enemy Release Hypothesis." These results show the importance of using community studies, such as the one described here, to understand the role of parasites in Lessepsian migration.

    Description: This study employs a multimethod approach to investigate the sediment distribution in two pocket beaches, Ramla Beach and Mellieha S Beach, in Malta. Both study sites were digitally reconstructed using unmanned aerial vehicle (UAV) photogrammetry. For each case, an ERT and a dense network of ambient seismic noise measurements processed through a horizontal-to-vertical spectral ratio (HVSR) technique were acquired. Electrical resistivity tomography (ERT) analysis enables the estimation of sediment thickness in each beach. HVSR analysis revealed peaks related to beach sediments overlying limestone rocks in both sites and also indicated a deeper stratigraphic contact in Mellieha S Beach. Based on ERT measurements, sediment thickness is calculated for each HVSR measurement. Interpolation of results allows for bedrock surface modelling in each case study, and when combined with digital terrain models (DTMs) derived from photogrammetric models, sediment volumes are estimated for each site. The geometry of this surface is analyzed from a geological perspective, showing structural control of sediment distribution due to a normal fault in Mellieha S Beach and stratigraphic control facilitated by a highly erodible surface in Ramla Beach. The results emphasize the importance of adopting a three-dimensional perspective in coastal studies for precise sediment volume characterization and a deeper understanding of pocket beach dynamics. This practical multimethod approach presented here offers valuable tools for future coastal research and effective coastal management, facilitating informed decision making amidst the growing vulnerability of coastal zones to climate change impacts.

    Description: This study investigates crustal accretion processes along the northern stretch of the Mid-Atlantic Ridge (MAR) between the Charlie Gibbs (52°-53°N) and Bight (57°N) transforms. These long-lived transform systems, active for more than 40 Ma, bound a ~ 550 km-long MAR segment influenced to the South by the Azores and to the North by the Iceland mantle plumes. The Bight transform is located at the tip of the Reykjanes Ridge, where the spreading direction, influenced by the southward propagation of the Iceland plume, changes from oblique (30° to the axis) to perpendicular to the axis. Four hundred kilometres to the south, the MAR is offset by the Charlie Gibbs transform system consisting of two long-lived right-lateral transform faults linked by a short ~ 40 km-long spreading segment. Previous expeditions surveyed large areas of these two transform systems, defining their main morphological features. Based on these bathymetric data, Expedition V53 of the R/V A.S. Vavilov carried out an intense dredging program coupled with magnetic surveys in an area spanning from 57° to 52°N, covering both the Bight and the Charlie Gibbs transform systems. We collected 1850 kg of rock samples including limestones, basalts, gabbros and mantle peridotites from 27 dredging sites, along with two 6-m long sedimentary cores. The sampled lithologies are globally in agreement with the contrasting morphological features of the two transform faults. We discuss here and compare the geology of these two major transform systems and assess the influence of the Icelandic plume on seafloor morphology at the Bight Fracture Zone.

    Description: Site effects refer to the modification of ground shaking caused by the local geological con- ditions that can result in the strong amplification of ground motion. The best-known cause for site effects is the presence of superficial soft soil deposits, which are considered in seismic design codes of many countries through the use of scaling factors. Rock sites are assumed to show no local site amplification. However, even at rock sites, seismic waves can be locally amplified at frequencies of engineering interest, with larger motion along one site-specific azimuth on the horizontal plane (the so called “directional site resonance or amplification”). These effects have been related to the pres- ence of large-scale open cracks or microcracks in different geological environments (faults, land- slides, volcanic areas) everywhere with a common signature: maximum amplification occurs trans- verse to the predominant fracture strike. In this paper, we summarize our main results obtained in the last decade with regard to several fault zones with different kinematics, where ground motion is polarized (and amplified) perpendicularly to the predominant fracture field as an effect of the stiffness anisotropy. In order to give a further constraint, we also show some cases where the direc- tional amplification effects were compared with the S-wave splitting analysis method.

    Description: Radio frequency (RF) signals transmitted by Global Navigation Satellite Systems (GNSSs) are exploited as signals of opportunity in many scientific activities, ranging from sensing waterways and humidity of the terrain to the monitoring of the ionosphere. The latter can be pursued by processing the GNSS signals through dedicated ground-based monitoring equipment, such as the GNSS Ionospheric Scintillation and Total Electron Content Monitoring (GISTM) receivers. Nonetheless, GNSS signals are susceptible to intentional or unintentional RF interferences (RFIs), which may alter the calculation of the scintillation indices, thus compromising the quality of the scientific data and the reliability of the derived space weather monitoring products. Upon the observation of anomalous scintillation indices computed by a GISTM receiver in the Mediterranean area, the study presents the results of the analysis and characterization of a deliberate, unclassified interferer acting on the L1/E1 GNSS signal bands, observed and captured through an experimental, software-defined radio setup. This article also highlights the adverse impacts of the interferer on the amplitude scintillation indices employed in scientific investigations, and presents a methodology to discriminate among regular and corrupted scintillation data.

    Description: A common practice of seismology is to analyze earthquake occurrence in terms of events catalogues, with the aim to either find useful correlations between internal mechanisms under study and their outcome in the spatial/temporal series of the events or, more directly, to assess some statistical rules from observations. With this approach, catalogues are often searched for some recognizable patterns or behaviors: in this work we present a software tool created to reveal a particular kind of events sequences. The idea follows from the concept of multiplets, a well known events pattern often found in seismic series. A multiplet is defined as a sequence of events, all near in space and time and exhibiting similar magnitudes. The amount of multiplets in seismic series is related, as it is for other clustering mechanisms, to underlying correlations in the physics of the events. The software, built from scratch, scans seismic catalogues in search of events clustered as “multiplets”: this is done through the thorough application of comparison tests whose parameters thresholds are both user defined and semi-automated. The tool is however more “general” in the sense that by varying values of the filtering parameters it can reveal other kind of patterns too. While we think that this tool can be thought as a general purpose space–time series analyzer, we have found it particularly useful when applied to the results of a seismic simulator with the purpose of assessing their adherence with the observed seismicity. It can be used as a sort of metric to quantify the simulation predictions effectiveness in terms of presence of similar multiplets distributions in simulated vs. real catalogues. The software has been entirely developed in the Wolfram Language (Mathematica), a commercial powerful environment for scientific calculus and results report, but the main computational routine has been also ported to python for open-source, copyleft usage.

    Description: Understanding whether fractures and faults impact the CO2 migration through the overburden is critical in the evaluation and monitoring of CO2 geological storage sites. We present a numerical model and workflow to describe the hydraulic behaviour of a fault located in the shallow part of the overburden. This helps to evaluate the sealing potential of the system in case of unwanted CO2 migration toward the surface and to design an efficient monitoring plan. The model configuration is representative of several experiments performed at real sites under quite shallow conditions (50–500 m). The model results, applied to a selected fault outcropping in the Apennines (Italy), show that most of the gas migrates through the high permeable footwall damage zone. A significant amount of gas then dissolves into the water, emphasizing the importance of accurate modelling to assess the hazard of CO2 leakage into near-surface aquifers or to the surface. The occurrence of pressure buildup close to the fault core points out that detailed modelling of the migration conditions is required to predict gas path through a fault zone.

    Description: We present the first high-resolution ultrashallow seismic image of a normal fault segment that ruptured the surface during the Mw 6.5 2016 Norcia earthquake (central Italy). This is the only fault, in the entire activated 25 km-long system, cutting a thick succession of Quaternary deposits, with an associated 3-m-high cumulative scarp. A 190-m-long profile crossing the fault was acquired and analyzed combining reflection seismic, non-linear multiscale refraction P-wave tomography and multi-channel analysis of surface waves. The joint interpretation of the seismic reflection, P- and S-wave velocity images unravels a 100-m-thick sequence of sandy-gravel alluvial fans, disrupted by a main normal fault zone, named as Valle delle Fonti fault (Vf1), which branches upward into three splays. The eastern splay of Vf1 matches with the 2016 coseismic surface rupture. Near-surface truncated reflections and growth strata in the hanging wall of the western and intermediate splays attest to their activity in Late Pleistocene-Holocene times. We also detect an additional normal fault in the footwall of Vf1, probably inactive since the Late Pleistocene. Comparing the seismic images with the Poisson's coefficient model and with the results of a previous electrical resistivity tomography, we constrain the lithology and the hydraulic behavior of the uppermost 50 m of the fault. A steep, W-dipping zone with high-Vp, very high Poisson's coefficient and low resistivity correlates with the eastern splay of Valle delle Fonti fault and unravels a water-saturated region. These results suggest that the fault zone may act as a partial barrier for horizontal fluid flow. Our findings indicate that the active fault zone detected by seismic imaging is much wider than what previously estimated from surface geological analyses. In terms of surface faulting hazard, this study confirms the effectiveness of high-resolution seismic surveys in defining the geometry and physical properties of active fault zones.

    Description: We analyze the interplay between hydrology, deformation and seismicity in the Matese massif, located in the Italian Southern Apennines. We find that this area is characterized by the concurrent action of two hydrologically-driven processes: the first is the deformation detected by GNSS data in the shallowest part (above the elevation of the major springs) of the Earth crust, in phase with the hydrological forcing; the second is the triggering of seismicity at depth with a delay suggesting a downward diffusive process. We study the first process by applying a Principal Component Analysis to the GNSS displacements time series, aiming to identify a common signal describing the largest data variance. We find that the maximum horizontal displacements associated with the first principal component (PC1) are larger than 1 cm in two GNSS sites and the PC1 temporal evolution is well correlated and in phase with the flow of the largest spring of the region, which we consider as proxy of the water content of the massif. This suggests that the main source of horizontal deformation is the water content fluctuations in the shallow portion of the Matese aquifer, in particular within fractures located in correspondence of the main mapped faults. The deformation rates caused by this process are one order of magnitude larger than the tectonic ones. Finally, we infer the second process by observing the correlation between the background seismicity and the spring discharge with a time lag of 121 days. In our interpretation, downward diffusive processes, driven by aquifer water content variations, propagate pore pressure waves that affect the faults strength favoring the occurrence of micro-earthquakes. This is supported by the values of hydraulic diffusivity (1.5 m^2/s) and rock permeability (3.2-3.8⋅10^−13 m^2), which are compatible with what is observed in karstified limestones.

    Description: The Tonga-Kermadec subduction zone represents one of the most active areas from both seismic and volcanic points of view. Recently, two planetary-scale geophysical events took place there: the 2019 M7.2 earthquake (EQ) with the epicentre in Kermadec Islands (New Zealand) and the astonishing 2022 eruption of Hunga Tonga-Hunga Ha’apai (HTHH) volcano. Based on the Lithosphere-Atmosphere- Ionosphere Coupling (LAIC) models, we analysed the three geolayers with a multiparametric approach to detect any effect on the occasion of the two events, through a comparison aimed at identifying the physics processes that interested phenomena of different nature but in the same tectonic context. For the lithosphere, we conducted a seismic analysis of the sequence culminating with themain shock in Kermadec Islands and the sequence of EQs preceding the HTHH volcanic eruption, in both cases considering the magnitude attributed to the released energy in the lithosphere within the respective Dobrovolsky area. Moving to the above atmosphere, the attention was focused on the parameters—gases, temperature, pressure—possibly influenced by the preparation or the occurrence of the events. Finally, the ionosphere was examined by means of ground and satellite observations, including also magnetic and electric field, finding some interesting anomalous signals in both case studies, in a wide range of temporal and spatial scales. The joint study of the effects seen before, during and after the two events enabled us to clarify the LAIC in this complex context. The observed similarities in the effects of the two geophysical events can be explained by their slightly different manifestations of releasing substantial energy resulting from a shared geodynamic origin. This origin arises from the thermodynamic interplay between a rigid lithosphere and a softer asthenosphere within the Kermadec-Tonga subduction zone, which forms the underlying tectonic context.

    Description: In this paper we present the new high-resolution magnetic anomaly map of the La Fossa Caldera system and Lipari island (Southern Italy), obtained by merging two low-altitude aeromagnetic surveys. In these islands a variegated ensemble of magnetic anomalies develops in the north-south direction. The La Fossa Caldera is characterized by very high-intensity and short-wavelength magnetic anomalies, related to mafic intrusive/effusive sources, mainly aligned along the NNW-SSE and NS faults. Instead, the Lipari island is characterized by lower intensity anomalies related to sources with more evolved chemistry, elongated in the NE-SW, NNE-SSW and EW of the subordinate faults. Both the two sets of structures belong to the Tindari-Letojanni strike slip fault-system, a regional lineament along which the southern side of the Aeolian Archipelago is emplaced. The study identifies three distinctive magnetic zones on the Lipari island: the southern, the central, and the north-western ones. The southern zone is characterized by negative magnetic monopoles in correspondence with the younger rhyolitic domes and a Curie Isotherm upwelling. The central part of the island has an average lower intensity of positive anomalies, corresponding to the less evolved products of the intermediate Lipari volcanic epochs. The north-western side is characterized by higher intensity anomalies related to older volcanic epochs. The interplay among strike-slip tectonics, chemistry of the uprising magmas, and the thermal setting has contributed to the overall anomaly pattern in this sector of the Aeolian Archipelago. This interpretation is supported by the application of digital enhancement to the total intensity magnetic anomaly field and by the spatial correlation analysis of the magnetic and volcano-tectonic features. The obtained insights are useful to better understand the relationship between arc volcanism and tectonics. Moreover, they can also outline new inferences to forecast future eruptions of the active La Fossa volcanic system. In fact, recent unrest signals were registered at La Fossa Cone, which is one of the present-day active volcanoes of the Aeolian Archipelago, along with Stromboli island.

In this paper, European chemical industry roadmaps from the past six years are assessed and compared to uncover how the industry envisions its role in the transition to net-zero emissions. The roadmaps are assessed in terms of ambition level, technology and feedstock strategies, investment needs and costs, agency and dependency on other actors, as well as timeline and concretion. Although net-zero pathways are often drawn out in the roadmaps, some also choose to emphasize and argue for less ambitious pathways with emission reductions of only 40-60 %. The roadmaps vary widely in terms of the importance they assign to mechanical and chemical recycling, switching to biogenic carbon and carbon dioxide as feedstock, electrification and hydrogen, and carbon capture and storage. A commonality though, is that low-tech or near-term mitigation pathways such as demand reduction, reuse or material efficiency are seldom included. High investment needs are generally highlighted, as well as the need for policy to create enabling conditions, whereas the agency and responsibility of the chemical industry itself is downplayed. Our analysis highlights that the chemical industry does not yet have a strong and shared vision for pathways to net-zero emissions. We conclude that such a future vision would benefit from taking a whole value chain approach including demand-side options and consideration of scope 3 emissions.

    Description: The results of the stock assessments of the European anchovy and European sprat, exploited by the Russian Federation in the Black Sea exclusively or predominantly, are presented. Based on the results of production modeling in 2022, the biomass value of the “Azov Sea” anchovy stock unit was in the buffer zone, between the target and limit biological reference points (Btr=BMSY=123.3 thousand tons, Blim=61.6 thousand tons); the time of stock recovery to the target level is 4 years. The fishing mortality rate (annual fishing loss, F) in 2022 is estimated to be F2022=0.20, which is lower than the biological reference point (Ftr=0.23). The estimation based on the lampara net surveys is more favorable: spawning stock biomass (exploitable) SSB2022 exceeded Btr calculated using Ricker’s “stock–recruitment” relationship by 19 %. The Azov Sea stock of the European anchovy has been characterized as “showing the evidence for recovery under heavy exploitation; subjected to the environmental effects”. In the 2022/2023 fishing season, fishing operations on the Black Sea stock of the European anchovy were mostly absent due to the state-imposed limitation in the Northwestern Black Sea and the western waters along the Southern Coast of Crimea (SCC). The biomass of the “Black Sea” anchovy stock unit in 2022, based on the results of JABBA trend modeling in “catch-only” representation, has been estimated as B2022=22.5 thousand tons, which is 3 % lower than the target reference point Btr=BMSY=23.2 thousand tons. The ratio between the current fishing mortality and its biological reference point was F2022/FMSY=0.467, which is indicative of its low exploitation. The catch composition of the European sprat in 2022–2023 was characterized by the prevalence of the 2+ and 3+ age classes (71–87 % by abundance). Based on XSA, in 2022, the spawning stock biomass (exploitable biomass) SSB2022 was 67.2 thousand tons, the recruitment was 56 billion ind., and the fishing mortality was F2022=0.29. The spawning stock biomass was in the buffer zone between the limit and target biological reference points by the biomass (SSB2022/SSBtr=1.433, SSB2022/SSBtr=0.841), while the fishing mortality was considerably lower than its biological reference point (F/F0.1=0.479). In 2022, the current Black Sea stocks of anchovy and sprat were officially characterized as “declining, little exploited”, with the possibility for underestimation of their biomass.
    Description: Представлены результаты оценки запасов хамсы и шпрота, эксплуатируемых Российской Федерацией исключительно или преимущественно в Черном море. В соответствии с результатами продукционного моделирования в 2022 г. значение биомассы «азовской» единицы запаса хамсы находилось в буферной зоне, между целевым и граничным биологическими ориентирами (Btr=BMSY=123,3 тыс. т, Blim=61,6 тыс. т), время восстановления запаса до целевого уровня составляет 4 года. Промысловая смертность (годовая промысловая убыль, F) в 2022 г. оценена на уровне F2022=0,20, что ниже биологического ориентира (Ftr=0,23). Оценка на базе лампарного учета более оптимистична: нерестовая (промысловая) биомасса SSB2022 на 19 % превысила Btr, найденный по зависимости Рикера «запас–пополнение». Запас азовской хамсы охарактеризован как «проявляющий признаки восстановления в условиях интенсивной эксплуатации, подверженный воздействию среды обитания». В путину 2022/2023 гг. промысел черноморской хамсы из-за административных ограничений в северо-западном районе и западных участках Южного берега Крыма (ЮБК) получил слабое развитие. Биомасса «черноморской» единицы запаса хамсы в 2022 г. по результатам трендового моделирования на JABBA в представлении «catch-only» оценена в B2022=22,5 тыс. т, что на 3 % ниже значения целевого ориентира Btr=BMSY=23,2 тыс. т. Отношение текущей промысловой смертности к своему биологическому ориентиру равнялось F2022/FMSY=0,467, что свидетельствовало о низком уровне эксплуатации. Структура промысловых уловов шпрота в 2022–2023 гг. характеризовалась преобладанием возрастных групп 2+ и 3+ (71–87 % по численности). Согласно XSA, в 2022 г. биомасса нерестового (промыслового) запаса SSB2022 составила 67,2 тыс. т, пополнение — 56 млрд экз., промысловая смертность F2022=0,29. Биомасса нерестового запаса находилась в буферной зоне между граничным и целевым биологическим ориентиром по биомассе (SSB2022/SSBtr=1,433, SSB2022/SSBtr=0,841) при промысловой смертности существенно ниже уровня своего биологического ориентира (F/F0.1=0,479). В 2022 г. текущие запасы черноморской хамсы и шпрота формально охарактеризованы как «убывающие, слабо эксплуатируемые», с признаками вероятной недооценки их биомассы.

    Description: Une campagne d’évaluation des petits pélagiques par acoustique ALPEL2018 a été menée le long de la côte algérienne par le Centre National de Recherche et de Développement de la Pêche et de l’Aquaculture (CNRDPA) entre décembre 2018 et février 2019 avec le navire de recherche BELKACEM GRINE. Cette campagne s’inscrit dans le cadre des activités de l’équipe ECOPEL de la Division de Recherche « Pêche » relatives à l’évaluation des stocks de petits pélagiques. L’objectif de cette campagne est d’utiliser les techniques d’écho-intégration combinées à des chalutages pélagiques pour estimer des indices instantanés de biomasse et d’abondance de neuf espèces cibles de petits pélagiques. La campagne ALPEL2018 a révélé une biomasse totale de 154 362 tonnes. La sardinelle (Sardinella aurita) est l’espèce la plus abondante avec 35% de la biomasse totale suivie du Chinchard méditerranéen (Trachurus mediterraneus), de la sardine (Sardina pilchardus) et de l’anchois (Engraulis encrasicolus) avec respectivement 23%, 16% et 14%. Le chinchard commun (Trachurus trachurus) et la bogue (Boops boops) sont faiblement représentés avec respectivement 9% et 3%. L’évaluation des stocks de T. picturatus et S. scombrus et S. japonicus n’a pas été effectuée en raison de leurs faibles présences dans les pêches d’identification.
    Description: An acoustic survey was conducted along the algerian coast by the National Centre for Research and Development of Fisheries and Aquaculture (CNRDPA) between December 2018 and February 2019 with the research vessel BELKACEM GRINE. This survey is part of the activities of the ECOPEL team of the "Fisheries" Research Division relating to the assessment of small pelagic stocks. The aim of this survey is to use echo-integration technics combined with pelagic trawls in order to estimate instantaneous indices of biomass and abundance for nine small pelagic target species. ALPEL2018 survey revealed a total biomass of 154 362 tons. Round sardinella is the most abundant species with 35% of the total biomass followed by the Mediterranean horse mackerel, sardine and anchovy with 23%, 16% and 14% respectively. The horse mackerel and the bogue are weakly represented with respectively 9% and 3%. T. picturatus, S. scombrus and S. japonicus stocks were not evaluated due to their low presence in the pelagic trawl hauls.

    Description: Sandy barriers are coastal features formed and reworked by terrestrial and marine-induced processes along decadal to millenary scale periods. In the semi-arid areas along the extended North African coast, these coastal landscapes are undergoing accelerated morphodynamical changes induced by intensifying anthropogenic and climate drivers in the last century. To quantify the latter, we assess the changes in sediment dynamics of the Ghar El Melh sandy barrier extended over the northern part of the Gulf of Tunis in Tunisia using sedimentological analysis and quantification of the aeolian flux. A total of 37 subsurface samples and 30 surface aeolian trapped ones were collected at the coastal dunes of Ghar El Melh. Our sedimentological analysis reveals a distribution of 97% of sandy sediments and 3% of silty facies. The modal statistical analysis suggests that there are three distinguishable sediment types with 87% of samples formed by fine sands with modal value of 0.16 mm. The mixture of these indicates mixed terrigenous and marine sources redistributed by the hydrodynamic processes. The measurement of the aeolian flow suggests a maximum value of 0.0022 kg.m.-1min-1 which occurs in dust storms. This study reveals the low detrital sand supplies to the lagoon-sea barrier of Ghar El Melh, results in its gradual submersion, further exposing the coastal lagoon and engendering severe ecological degradations.

    Description: There is a growing need to evaluate how fishing activities is being affecting the ecosystem. The study seeks to frame the assessment of risk status of three main fisheries operating in the Algerian coastal ecosystem, which are trawl, purse seine, and small-scale fisheries. The ecosystem-based fisheries assessment has been suggested to conduct the present study. Tier 2 process analysis has been used since the qualitative data was not rich. Across the nested risk design, the trawl, purse seine, and small-scale fisheries risk indices were projected in the yellow zone. The highestfishery risk index(FRI)was observed in the trawl fishery (1.363), followed by the small-scale fishery (1.309), then the lowest value was found in the purse seine fisheries (1.114). The purse seine fishery risk index differed significantly from both of trawl and small-scale fisheries risk indices, whereas there was no significant difference between trawl fishery risk index and small-scale fishery risk index. A proper management measures were to improve the fisheries risk situations.

    Description: This work aims to investigate the trace metal contamination of El Mellah Lagoon by assessing their accumulation levels in the tissues of the brackish water cockle Cerastoderma glaucum (Bivalvia: Cardiidae). Our findings show that copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) concentrations in cockles ranged between 0.81-2.09, 4.12–6.72, 0.09–0.15, and 0.39–0.76 mg/kg soft tissue dry weight respectively, in ascending order of: Cd〈 Pb〈 Cu〈 Zn. Statistical analysis reveals significant seasonal variations in measured metals, with the highest values all recorded in autumn but remaining well below the recommended guide values. Overall, our study excludes the existence of an ecotoxicological threat linked to the presence of essential (Cu, Zn) and toxic (Cd, Pb) metals in the cockles' flesh.

    Description: The dynamics of lipid content in the body of anchovy (Engraulis encrasicolus) at various stages of its life cycle has been analyzed for the time range from 2020 to 2022. This article indicates that the content of constructive and energy-bearing substances in the anchovy body is discernibly dependent on the fish’s age: the lipid content in fingerlings is lower than in older individuals. Based on the analysis of the inter-seasonal dynamics of the lipid content in the anchovy body, it has been identified that the lowest lipid content is typical for this fish in April, and the highest lipid content is observed in October. The analysis of the inter-annual dynamics of the lipid content in the anchovy body at the end of its feeding period has shown that, for the last three years, there has been a trend towards a gradual increase in the content of lipids to 16–18 %.
    Description: Проведен анализ динамики содержания липидов в теле хамсы (Engraulis encrasicolus) в различные периоды ее жизненного цикла с 2020 по 2022 г. В статье показано, что разница в содержании энергопластических веществ в теле хамсы четко прослеживается в зависимости от возраста рыб: у сеголеток количество липидов ниже, чем у старшевозрастных особей. На основе анализа межсезонной динамики содержания липидов в теле хамсы установлено, что минимум содержания липидов характерен для рыб в апреле, а максимум — в октябре. Анализ межгодовой динамики содержания липидов в теле хамсы в конце нагульного периода показал, что в последние три года наблюдается тренд на постепенное увеличение их количества до уровня 16–18 %.

    Description: Variability in the yield of the Azov Sea tyulka (Azov Sea stocks of the Black Sea–Caspian sprat) generations affected by the environmental changes in 1993–2022 has been estimated. Stock assessments of the ichthyoplankton have been conducted in the Azov Sea in June for more than 50 years. Evaluation of the fingerling abundance is carried out in the course of the surveys with lampara nets in August. During the survey period, considerable environmental changes attributable to natural and anthropogenic factors have been identified; they heavily influence the yield of the Azov Sea tyulka generations.

    Description: The Proletarsky Reservoir located in the Kuma–Manych Depression is a water body that is highly important for the fisheries in the Southern Russia. Its western part is the most economically valuable, which necessitates the investigation of its zooplankton serving as a food source for the larvae and planktivorous fish. This work presents the results of investigation of the zooplankton community in this area during fish spawning campaign in the spring seasons of 2021–2022. In spring, the zooplankton was represented by 4 groups of organisms (30 species), which include rotifers, copepods, cladocerans, and meroplankton. Among them, the copepods were the most diverse, with the species of Cyclopoida suborder being the most prevalent. The rotifers were the most abundant, comprising 67 % of the total zooplankton abundance. The cladocerans comprised the major part of the zooplankton biomass; their share in the total biomass consistently remained at 79 %. The total biomass of the zooplankton exceeded 300 mg/m3, which is sufficient to provide the planktivorous fish species and their larvae with a food source.
    Description: Пролетарское водохранилище, расположенное в Кумо-Манычской впадине, является важным водным рыбохозяйственным объектом юга России. Западный участок водохранилища имеет наибольшее рыбохозяйственное значение, что обуславливает актуальность исследования зоопланктона, являющегося кормовой базой личинок и планктоноядных рыб. В работе представлены результаты изучения в весенние сезоны 2021–2022 гг. зоопланктонного сообщества на этой акватории в период нереста рыб. Зоопланктон весной был представлен 4 группами организмов (30 видов), которые включают коловраток, веслоногих и ветвистоусых ракообразных, меропланктон. Наиболее разнообразны веслоногие ракообразные, среди которых доминировали представители п/отр. Cyclopoida. Коловратки характеризовались высокой численностью, составляющей более 67 % общего количества зоопланктеров. Основу биомассы зоопланктона формировали веслоногие ракообразные, доля которых в общей биомассе стабильно соответствовала 79 %. Общая биомасса зоопланктона составляла более 300 мг/м3, что является хорошим уровнем кормовой базы для планктоноядных рыб и их личинок.

    Description: This work presents quantitative data collected in the course of zander and roach artificial reproduction in the hatcheries of the Krasnodar Territory in 2023. Based on the surveys, 4.68 t of roach and 17.5 t of zander entered the reservoirs of Yeysk Experimental Hatchery for spawning. For the first time during the long-term observations, young individuals of low reproductive quality prevailed in the roach spawning stock. During the downstream migration, roach juveniles were absent in catches, and zander juveniles occurred very sporadically, which indicates their increased loss during all stages of early ontogenesis. The data collected in Beysug Hatchery gives evidence of 2.484 t of roach and 2.557 t of zander entering its reservoirs for spawning. In June–July, during the downstream migration, 16.48 million ind. of roach juveniles, which weight ranged from 0.3 to 1.2 g, were recorded; for zander juveniles these values were 0.140 million ind. and 0.91–1.53 g. The downstream migration of juveniles continued in August. At the floodgate of East-Akhtarsk Hatchery, the monitoring of breeders recorded 0.457 t of roach and 0.088 t of zander. The breeders were of low reproductive quality. Based on quantitative evaluation, the reproduction yield in the East-Akhtarsk Hatchery reservoir was 153.4 million ind. of roach (weight ranging from 0.3 to 0.96 g) and 102.25 million ind. of zander (weight 1.28–2.07 g). The monitoring of breeders entering the limans of Chernoerkovsk Hatchery recorded 8.0 t of roach and 12.85 t of zander. Chernorkovsk Hatchery showed the highest results: 426.32 million ind. of roach juveniles (weight 0.3–0.9 g) and 218.16 million ind. of zander juveniles (weight 0.47–3.37 g). Analysis of the obtained data has shown that low reproductive efficiency of both roach and zander is indicative for almost all investigated reservoirs of the hatcheries.
    Description: В работе приводятся материалы, характеризующие количественные показатели искусственного воспроизводства судака и тарани в нерестово-выростных хозяйствах Краснодарского края в 2023 г. По учетным данным на нерест в водоемы Ейского ЭХРВР зашло 4,68 т тарани и 17,5 т судака. Впервые за ряд лет наблюдений в нерестовом стаде тарани преобладали младшевозрастные особи с низкими рыбоводными показателями. В период ската молодь тарани в уловах отсутствовала, а молодь судака встречалась единично, что свидетельствует о повышенном отходе молоди на всех этапах раннего онтогенеза. По данным Бейсугского НВХ на нерест в водоемы было пропущено 2,484 т тарани и 2,557 т судака. При скате молоди в июне–июле было учтено 16,48 млн экз. молоди тарани массой 0,3–1,2 г и 0,140 млн экз. молоди судака массой 0,91– 1,53 г, в августе скат молоди продолжался. При мониторинге захода производителей на шлюзе Восточно-Ахтарского НВХ было учтено 0,457 т тарани и 0,088 т судака. Производители характеризовались низкими рыбоводными показателями. По итогам бонитировочного учета объемы воспроизводства в водоемах ВАНВХ составили 153,4 млн экз. тарани массой 0,3–0,96 г и 102,25 млн экз. судака массой 1,28–2,07 г. При мониторинге захода производителей в лиманы ЧНВХ было учтено 8,0 т тарани и 12,85 т судака. На Черноерковском НВХ получены самые высокие результаты, всего было учтено 426,32 млн экз. молоди тарани массой 0,3–0,9 г и 218,16 млн экз. судака массой 0,47–3,37 г. Анализ полученных материалов свидетельствует о том, что практически во всех исследуемых водоемах НВХ отмечается низкая эффективность воспроизводства молоди тарани и судака.

    Description: Notre étude a pour but d'évaluer l'effet des traitements post-capture (transport et hygiène) sur la qualité des produits de la pêche vendus au marché de Bou-Ismail comme région côtière et de Khemis Miliana comme région interne. L'étude s'est déroulée du mois d'Avril au mois de Juillet 2013. La méthodologie utilisée est celle d'une évaluation de la qualité organoleptique et microbiologique. Cette évaluation a été investiguée pendant la vente dans les deux régions. Les résultats de l’évolution des différents germes obtenus ont été comparés selon la région de prélèvement, l’espèce étudiée et la période du prélèvement. L'évaluation organoleptique et bactériologique indique que les poissons de Bou-Ismail (la Sardine et la Crevette) ont une bonne qualité et une très bonne fraicheur, alors que le Rouget a une qualité satisfaisante, en comparaison avec celles de Khemis Miliana qui ont une qualité satisfaisante et une fraicheur modérée, donc une diminution de la qualité au niveau de la région interne par rapport à la région côtière. Cependant, les poissons analysés sont exempts de germes potentiellement pathogènes tels que Salmonella sp.

    Description: The abundance of the sterlet population in the Don River is maintained by means of annual releases of its juveniles. For the reproduction, the breeders from the broodstock created in the Don Sturgeon Hatchery are used. Over 2019–2022, sturgeon hatcheries of the Azov-Don Branch of the FSBI “Glavrybvod” (Main Basin Department for Fisheries and Conservation of Aquatic Biological Resources) at the Don River downstream from Tsimlyansk Reservoir released 6.893 million sterlet juveniles exceeding 1.5 g in weight. Analysis of the data has shown that the efficiency of reproduction in this sturgeon species depends on the quality of the reared juveniles and the breeders involved in reproduction.
    Description: Поддержание численности популяции стерляди в р. Дон осуществляется за счет ежегодных выпусков молоди. Для выполнения воспроизводственных работ используются производители из ремонтно-маточного стада (РМС), сформированного на ОРЗ «Донской». За период 2019–2022 гг. осетровыми рыбоводными заводами Азово-Донского филиала ФГБУ «Главрыбвод» в р. Дон ниже Цимлянского водохранилища было выпущено 6,893 млн экз. молоди стерляди массой 1,5 г и более. Анализ данных показал, что эффективность воспроизводства этого вида осетровых рыб зависит от качества используемых в воспроизводственном процессе производителей и выращенной молоди.

    Description: The aim of the current study was the assessment of a Polycyclic aromatic hydrocarbon (PAHs) toxicity on an ascidian species, Styela plicata. Acute and subacute toxicity of naphthalene (NAP) has been determined using five increasing concentrations (0.5, 1, 1.5, 2.5 and 5 mg/l) during 96h of exposure. The half lethal concentration (LC50, 96h) value of naphthalene for S. plicata was 2.41 mg/l. Furthermore, the filtration activity decreased in the five tested concentrations of NAP; a significant decrease by 69% and 91.8% was observed after 1h in the groups exposed to C1 and C5, respectively. A similar pattern was noted after 2h of filtration; the decrease was estimated to 39% in C1 and 72.5% in C5. The results from this bioassay confirmed the toxicity of NAP on S. plicata; we also provided information about the use of S. plicata as a potential bioindicator species for the assessment of PAHs toxicity.

    Description: The bioinvasion has increased in recent years with climate change, and some invasive species have caused significant damage to the marine ecosystem, including a great loss of biodiversity. The studied seagrass is a marine tropical phanerogam introduced in the Mediterranean at the end of the 19th century and in southern Tunisia in 2003. In this study we record this species for the first time in northern Tunisia, precisely in the Punic Port of Carthage-Salammbo. Surveys were carried out on foot around the Punic Port, and measurements/photos were taken on site, and others in the laboratory on taken samples. Most of these measures do not differ from those carried out elsewhere in the Mediterranean. For the moment, the plant does not occupy a large part of the port buttom, but it may invade all the area in the future.

    Description: Over the course of long-term studies, the contribution of some sturgeon hatcheries into the population abundance of the sturgeon species in the Azov and Black Sea Basin has been investigated. For this purpose, the genotypes of the Russian sturgeon and starry sturgeon breeders from the hatchery broodstocks have been analyzed and compared with the sturgeon juveniles caught in the natural water bodies to identify their relation. It has been found out that the frequency of occurrence of the juveniles spawned by the breeders from the hatchery broodstocks does not correlate with the number of juveniles released by the corresponding breeding facility. The largest share of the investigated Russian sturgeon juveniles originated from the breeders from the Don Sturgeon Hatchery (77 %); the offspring of the breeders from the Temryuk Sturgeon Hatchery comprised 20 % of the total number, and 3 % of the juveniles originated from the Grivensk Sturgeon Hatchery. Out of the investigated starry sturgeon juveniles, the share of the offspring was 37 % for the Don Sturgeon Hatchery, 61 % for the Grivensk Sturgeon Hatchery, and 2 % for the Temryuk Sturgeon Hatchery.
    Description: В ходе многолетних исследований изучен вклад отдельных осетровых рыбоводных заводов (ОРЗ) в пополнение численности популяции осетровых видов рыб Азово-Черноморского бассейна. Для этого были проанализированы генотипы заводских производителей русского осетра и севрюги и выловленной в естественных водоемах молоди осетровых рыб, проведено их сопоставление на предмет родства. Выявлено, что частота встречаемости молоди, являющейся потомством заводских производителей, не коррелирует с объемами выпуска молоди конкретными воспроизводственными предприятиями. Наибольшую долю из проанализированной молоди русского осетра составляли потомки рыб с ОРЗ «Донской» (77 %), потомки рыб с Темрюкского ОРЗ составляли 20 %, с Гривенского ОРЗ — 3 %. Среди молоди севрюги доля потомков производителей с ОРЗ «Донской» составляла 37 %, с Гривенского ОРЗ — 61 %, с Темрюкского ОРЗ — 2 %.

    Description: A short beaked common dolphin was found stranded on March 3rd 2021, on Hammamet beach (Central-eastern Tunisia). This is a rare stranding event since it represents the third documented stranded individual reported on Tunisian coastline for half a century. Necropsy of the freshly dead female dolphin was conducted to know the presumable cause of death. The pregnant dolphin was bearing a mid-term female fetus with fully developed organs. Detailed biometric data were taken for both individuals. Samples were collected and preserved in the tissue bank of the national stranding network. The freshly dead fetus is preserved at the oceanographic museum for scientific collection. The rare stranding of this species observed here would be attributed to the small population frequenting Tunisian waters. This note improves knowledge on this poorly studied species in the south-central Mediterranean area.

    Description: Over the course of the monitoring surveys conducted in 2021–2022, the specific features of the starry sturgeon reproduction have been investigated, which covered the span from the adaptation of breeders to the release of juveniles into a natural water body. The results of this study indicate that the starry sturgeon females from the broodstock have low reproduction capacity, as well as decreased embryo survival rates and larvae yield. The starry sturgeon juveniles reared in tanks were characterized by low growth rates, decreased feed conversion efficiency, and acceptable physiological status. It has been shown that rearing the starry sturgeon juveniles in tanks is less expedient than using a combined method.
    Description: В ходе мониторинговых работ, проводимых в 2021–2022 гг., были рассмотрены особенности воспроизводственного процесса севрюги: от выдерживания производителей до выпуска молоди в естественный водоем. Результаты исследования показали, что самки севрюги из ремонтно-маточного стада обладают невысоким репродуктивным потенциалом, выживаемость эмбрионов и выход личинок снижены. Молодь севрюги, выращиваемая в бассейнах, характеризовалась невысоким темпом роста, сниженными показателями трансформации пищи, удовлетворительным физиологическим состоянием. Показано, что выращивание молоди севрюги бассейновым методом менее эффективно, чем комбинированным.

    Description: We investigate the role of auroral particle precipitation in small-scale (below hundreds of meters) plasma structuring in the auroral ionosphere over the Arctic. In this scope, we analyze together data recorded by an Ionospheric Scintillation Monitor Receiver (ISMR) of Global Navigation Satellite System (GNSS) signals and by an All-Sky Imager located in Longyearbyen, Svalbard (Norway). We leverage on the raw GNSS samples provided at 50 Hz by the ISMR to evaluate amplitude and phase scintillation indices at 1 s time resolution and the Ionosphere-Free Linear Combination at 20 ms time resolution. The simultaneous use of the 1 s GNSS-based scintillation indices allows identifying the scale size of the irregularities involved in plasma structuring in the range of small (up to few hundreds of meters) and medium-scale size ranges (up to few kilometers) for GNSS frequencies and observational geometry. Additionally, they allow identifying the diffractive and refractive nature of fluctuations on the recorded GNSS signals. Six strong auroral events and their effects on plasma structuring are studied. Plasma structuring down to scales of hundreds of meters is seen when strong gradients in auroral emissions at 557.7 nm cross the line of sight between the GNSS satellite and receiver. Local magnetic field measurements confirm small-scale structuring processes coinciding with intensification of ionospheric currents. Since 557.7 nm emissions primarily originate from the ionospheric E-region, plasma instabilities from particle precipitation at E-region altitudes are considered to be responsible for the signatures of small-scale plasma structuring highlighted in the GNSS scintillation data.

    Description: A 2-year dataset of a stand-alone mooring, deployed in November 2020 down the Levante Canyon in the eastern Ligurian Sea, is presented. The Levante Canyon Mooring (LCM) is a deep submarine multidisciplinary observatory positioned at 608 m depth in a key ecosystem area. The Levante Canyon hosts a valuable and vulnerable ecosystem of deep-living cold-water corals (CWCs), studied and monitored since 2013 through integrated mapping of the seabed and water column. The 2-year dataset, acquired on the mooring and presented here (data from November 2020 to October 2022), includes measurements conducted with both current meters and conductivity–temperature–depth (CTD) probes and provides information about the hydrodynamics and thermohaline properties across almost the entire water column. The observatory is still ongoing, and the dataset is regularly updated. All the described data are publicly available from https://doi.org/10.17882/92236 (Borghini et al., 2022). They must therefore be preserved and are of considerable scientific interest.

    Description: Im Jahr 1529 erließ Herzog Georg von Sachsen eine neue Bergordnung für die Bergwerke in Freiberg. Im Gegensatz zum Erzgebirge, wo die 1509 erlassene Annaberger Bergordnung allgemeine Gültigkeit erlangt hatte, beharrte der Rat zu Freiberg auf ein in Teilen eigenständiges Bergrecht für die Stadt. Die Freiberger Bergordnung wurde vom Rat zu Freiberg gemeinsam mit den Gewerken im Beisein von Herzog Georg erstellt. In den 38 Artikeln wurde im Wesentlichen der Inhalt der Annaberger Bergordnung wiederholt. Neu für Freiberg war die Abrechnung und Austeilung sowie Veranschlagung der Zubuße in einem festgesetzten Zeitraum. Im Gegensatz zur Abrechnung in vier Quartalen, wie es im Erzgebirge seit 1476 Vorschrift war, erfolgte diese in Freiberg zu drei Terminen im Jahr. Weiterhin wurde darauf verwiesen, dass die Freiberger Bergbeamten die Eide analog der Annaberger Bergordnung leisten sollten.

    Description: This article presents the results of fish resource assessment conducted in 2021–2022 in the Veselovsky Reservoir and characterizes its major commercial fish species. The results of the investigation of the commercial fish stocks in the Veselovsky Reservoir characterize the physiological status of the populations as good based on a number of parameters (visceral fatness, conditional factor, fertility), which results from the abundance and diversity of the food supply and favorable environmental conditions. In the past two years, a noticeable increase in the stock abundance of commercial fish species has been observed in the Veselovsky Reservoir, which provides the ground to expect the formation of a stable resource for commercial fishing in the near future.

    Description: Crayfish is a long-established fisheries target in the water bodies of the Rostov Region. This work presents the data characterizing the pollution of water and bottom sediments with petroleum products, organochlorine pesticides, and heavy metals. The changes in the biological parameters of the crayfish population in the reservoir have been reviewed. The status of crayfish population, their stocks and abundance in the reservoir are conditional upon the existing range of abiotic and anthropogenic factors. The ecological improvement of the environment in 2020–2022 and the low concentrations of petroleum products, organochlorine pesticides and heavy metals facilitated the recovery of the crayfish exploitable stock that reached 32.9 t in 2022. In the consistently favourable conditions, under a regular monitoring of the productive crayfish populations, sustainable exploitation of their stocks and responsible control over their harvesting implemented by the fisheries protection authorities, this reservoir will retain its crayfish commercial importance.
    Description: Раки — традиционный объект промысла в водных объектах Ростовской области. В работе представлены материалы, характеризующие загрязнение воды и донных отложений нефтепродуктами, хлорорганическими пестицидами и тяжелыми металлами. Дан обзор изменений биологических параметров популяции раков в водохранилище. Состояние популяции раков, их численность и запасы в водохранилище определяет сложившийся комплекс абиотических и антропогенных факторов. Улучшение экологической ситуации в 2020–2022 гг. и низкие концентрации нефтепродуктов, хлорорганических пестицидов и тяжелых металлов способствовали восстановлению промыслового запаса к 2022 г. до уровня 32,9 т. В стабильно благоприятных трофических условиях, при систематическом мониторинге ракопродуктивных популяций, рациональном использовании запасов раков и ответственном контроле промысла в водохранилище органами рыбоохраны водохранилище сохранит ракопромысловый статус.

    Description: The wave regime of the coastal waters in the Southeastern Russian sector of the Black Sea has been described based on the data of the wave-measuring station located in the area adjacent to Tuapse. The data of observations for the time range from 1975 to 2005 were used. Such characteristics as wave types, fetch lengths, wave type repeatability by month and direction, wave repeatability for the waves of different heights, the number of days with storm wave action, and the duration of storm wave conditions have been investigated. It is shown that the sea wave action in the coastal waters near Tuapse is determined by the observed wind, the influence of open sea waves, as well as by the orography of the sea port area, open to the wave systems from the southwest, south, and, to a lesser extent, from the west.

    Description: Benthic organisms are among the crucial components of an aquatic ecosystem, taking part in the circulation of matter and facilitating self-purification processes in water bodies. A number of researchers indicate a positive correlation between the content of toxicants in benthic organisms and their habitat, which leads to recommendations to use various species of bottom invertebrates as indicators for the pollution monitoring of aquatic ecosystems. Molluscs accumulate hydrocarbons (HC) at a higher rate than they excrete them from their body due to the absence or, at least, low development of the hydrocarbon hydroxylase detoxification system. Bivalve molluscs Mytilus galloprovincialis, a species actively involved in the filtration of the bottom water layer and coming into contact with polluted substrate, served as a subject for this investigation. This mollusc species is a valuable food source; as a part of the Azov and Black Sea zoobenthos community, it is widely spread and abundant. The experiments have been conducted on M. galloprovincialis individuals of the average length of 3–4 cm cultivated on the mussel collectors in the acceptably pure waters in the area near Bolshoy (Big) Utrish Cape. Two series of the experiments with different exposition time have been conducted: the short-term one (5 days) and a longer one (21 days). During the experiments, the bottom sediments (BS) of various pollution level were used: 0.03, 0.5, 0.6, 1.0, 2.5, and 5.0 g/kg petroleum products, dry weight. Following the laboratory tests, it has been found that the dynamics of accumulation and subsequent extraction of hydrocarbons from the soft tissues in mussel is dependent on the pollution level of bottom sediments.
    Description: Бентосные организмы относятся к важнейшим компонентам водной экосистемы, участвующим в круговороте веществ и самоочищении водоема. Рядом авторов отмечена положительная корреляция между содержанием токсикантов в бентосных организмах и местом их обитания, в связи с чем часто предлагается использовать различные виды донных беспозвоночных в качестве индикаторов при мониторинге загрязнения водных экосистем. Моллюски легко аккумулируют, но сравнительно медленно выводят углеводороды (УВ) из организма в связи с отсутствием или, по крайней мере, слабым развитием углеводород-гидроксилазной детоксицирующей системы. Объектом исследования служили двустворчатые моллюски вида Mytilus galloprovincialis, которые активно участвуют в процессе фильтрации придонной воды и контактируют с загрязненным грунтом. Этот вид моллюсков, имеющий кормовую ценность, широко распространен среди организмов зообентоса Азовского и Черного морей. В экспериментах использован M. galloprovincialis среднего размера длиной 3–4 см, выращенный на коллекторах в условно чистом районе вблизи м. Б. Утриш. Проведены две серии экспериментов с различной экспозицией: краткосрочная (5 суток) и более длительная (21 сутки). В экспериментах использовали донные отложения (ДО) различной степени загрязненности: 0,03; 0,5; 0,6; 1,0; 2,5 и 5,0 г/кг сухой массы нефтепродуктов (НП). В ходе лабораторных экспериментов установлено, что в мягкой ткани мидий динамика накопления и последующего выведения углеводородов зависит от уровня загрязненности донных отложений.

    Description: The 60–80s of the last century were the period of the most rapid development of commercial oceanology in the Azov and Black Sea Scientific Research Institute of Marine Fisheries and Oceanography (AzCherNIRO, further renamed YugNIRO). In addition to the monitoring of oceanographic processes, it was involved in the areas of general marine ecology, monitoring of marine pollution, and space oceanology. Oceanographic information is used in forecasting the state of aquatic ecosystems at various timescales and is crucial for fishing forecasts. In 1981, a satellite data reception center was established in AzCherNIRO. In the 80–90s, in YugNIRO, an optimal procedure was created for multidimensional predictive monitoring of the state of the Black Sea ecosystem. In September 1986, within the Laboratory of Commercial Oceanology of the Black Sea, a group for the conservation of marine ecosystems was created, which turned into a sector in January 1989, and into a separate laboratory in December 1996. Its reasearchers carried out multidisciplinary environmental studies, investigating the ecological status of the aquatic areas affected by the facilities of the marine industry during their operation, monitoring the level of soil contamination, and excercising the toxicological control of fish and fish products. YugNIRO oceanological studies conducted in the World Ocean from the early 1970s to the early 1990s made it possible to link the productivity and catches of exploitable species to the atmospheric circulation, changes in the climatic fields of currents, as well as to the geo- and heliophysical factors, which enabled the fishing predictions with a one-year lead time or more for the fishing areas of the Central, Southeastern and Southwestern Indian Ocean, the Patagonian Shelf, and the Indian Ocean sector of Antarctica. In the 70–90s and early 2000s, YugNIRO conducted marine geological studies facilitating fishing operations and environmental protection in the Gulf of Aden, on the bottom elevations of the tropical and subtropical parts of the Indian Ocean, in the Antarctic Shelf area, and in the Black and Azov Seas. This article lays down the current major goals and prospects of commercial oceanology.
    Description: 60–80-е годы прошедшего столетия были в АзЧерНИРО (ЮгНИРО) периодом наиболее активного развития промысловой океанологии. Кроме мониторинга океанографических процессов она начала внедряться в сферы общей экологии моря, мониторинга загрязнения моря, космической океанологии. Океанографическая информация используется при разработке прогнозов состояния водных экосистем различной заблаговременности и является неотъемлемой составляющей рыбопромысловых прогнозов. В 1981 г. в АзЧерНИРО был создан центр приема спутниковой информации. В 1980–1990-х гг. в ЮгНИРО была создана оптимальная для Черного моря схема комплексного прогностического мониторинга состояния его экосистемы. В сентябре 1986 г. в составе лаборатории промысловой океанологии Черного моря была создана группа, в январе 1989 г. — сектор, в декабре 1996 г. — лаборатория охраны морских экосистем. Сотрудниками лаборатории проводились комплексные экологические исследования состояния акваторий предприятий морехозяйственого комплекса в условиях их производственной деятельности, контроль уровня загрязненности почв, токсикологический контроль рыбы и рыбопродукции. Океанологические исследования ЮгНИРО, проводимые в Мировом океане с начала 1970-х до начала 1990-х гг., позволили получить систему связей урожайности и вылова промысловых объектов с особенностями атмосферной циркуляции, изменениями макромасштабных полей течений, гео- и гелиофизическими факторам для прогноза промысловых характеристик с заблаговременностью год и более в промысловых районах центральной, юго-восточной и юго-западной частей Индийского океана, в районе Патагонского шельфа, в индоокеанском секторе Антарктики. Выполнение морских геологических работ в рыбопромысловых и природоохранных целях проводилось ЮгНИРО в 1970–1990-х и в начале 2000-х гг. в Аденском заливе, на поднятиях тропической и субтропической частей Индийского океана, на шельфе Антарктиды, в Черном и Азовском морях. В статье формулируются основные современные цели и пути развития промысловой океанологии.

    Description: Length-weight relationships (LWRs), length-length relationships (LLRs), and condition factor of Pseudotolithus elongatus from the coastal waters of Rivers State, Nigeria, were studied. Specimens were collected from the catches of fishermen using various fishing gear. The dominant length ranged from 20 to 26 cm, with a mean length of 22.65±3.06cm. The monthly length-weight relationship was estimated separately for male and female, with the b values indicating positive allometric growth (b 〉 3.00) in November, January, and February for both male and female. The females experienced negative allometric growth (b 〈 3.00) in December, March, and April, while the males exhibited a negative allometric growth pattern in April. The combined b value of LWRs (TL vs. BW) indicates positive allometric growth, and SL vs. BW indicates negative allometric growth. Also, the b value of LLR (TL vs. SL) indicates negative allometric growth. The condition factors varied for both sexes, ranging from 0.35 to 1.2 in males and 0.57 to 1.14 in females, while the combined condition factor ranged from 0.35 to 1.2. The present findings will provide useful information for a well-organized and significant exploitation and regulation of Sciaenid species following the aftermath of massive fish kills and continuous exploitation of fish species in the study area.

    Description: Veselovsky, Proletarsky and Krasnodar Reservoirs are located in the area, extensively used for various agricultural purposes. This industry requires the use of means to protect cultivated plants from pests. When land is treated with pesticides, these substances can enter water bodies of fisheries importance through the air and soil, accumulate in bottom sediments and have a negative impact on the vital functions of hydrobionts. Using the method of high-performance liquid chromatography (HPLC), 20 active ingredients (AI) of pesticides of modern classes that are used in agriculture of the region and the half-life of which can exceed six months have been investigated. In preparation for chromatography, pesticides were extracted from the samples of water and bottom sediments with dichloromethane, followed by drying and purification of the extracts. It has been established that the concentrations of pesticide AIs in the aquatic living environment of the investigated reservoirs are more than an order of magnitude lower than the established maximum permissible concentrations (MPCs).
    Description: Веселовское, Пролетарское и Краснодарское водохранилища расположены в регионах с интенсивной и разнообразной сельскохозяйственной деятельностью. Применение средств защиты культурных растений от вредителей является обязательным условием в данном виде производства. При обработке земель пестицидами эти вещества через воздух и почву могут попасть в водоемы рыбохозяйственного назначения, осесть в донных отложениях и оказать негативное влияние на жизнедеятельность гидробионтов. Методом высокоэффективной жидкостной хроматографии (ВЭЖХ) определяли 20 используемых в сельском хозяйстве региона действующих веществ (ДВ) пестицидов современных классов, период полураспада которых может превышать полгода. Для подготовки к хроматографии проводили экстракцию ДВ пестицидов из проб воды и донных отложений дихлорметаном с последующим осушением и очисткой экстрактов. Установлено, что концентрации ДВ пестицидов в среде обитания гидробионтов исследованных водоемов более чем на порядок ниже установленных предельно допустимых концентраций (ПДК).

    Description: This work presents the results of long-term assessment of the influence of the Azov Sea salinity changes and predation pressure of the Black Sea gelatinous invading species—ctenophores and scyphozoans—on the development of fodder zooplankton. It is shown that the increase in the salinity of the water body leads to considerable changes in the taxonomic structure of its community. Freshwater and brackish-water species are being replaced by characteristic marine taxa from the Black Sea that are gradually becoming dominant. The number of the species immigrating from the Black Sea is growing; their range extends beyond the Southern Azov Sea. Some of them are rapidly developing far outside the area directly influenced by the Black Sea waters, including Taganrog Bay. The gelatinous predatory ctenophores and jellyfish from the Black Sea start to appear in this water body. Simultaneous development of these species escalates the consumption of fodder zooplankton by invaders. More substantial changes in taxonomic structure of the community are also observed; its development indicators and production are decreasing.
    Description: В работе приведены результаты многолетних исследований по оценке влияния изменения солености Азовского моря и хищничества черноморских желетелых вселенцев — гребневиков и сцифоидных медуз на развитие кормового зоопланктона. Показано, что увеличение солености водоема существенно изменяет таксономическую структуру сообщества. Происходит вытеснение пресноводных и солоноватоводных видов животных типично морскими черноморскими таксонами, которые постепенно приобретают статус доминирующих. Заметно расширяется список черноморских мигрантов, их ареал перестает ограничиваться южной частью Азовского моря. Некоторые из них активно развиваются далеко за пределами наибольшего влияния черноморских вод, включая Таганрогский залив. В водоеме появляются черноморские желетелые хищные гребневики и медузы. При одновременном развитии популяций этих видов выедание кормового зоопланктона вселенцами заметно усиливается. Наблюдаются более существенные изменения таксономической структуры сообщества, снижаются количественные показатели его развития и продукция.

    Description: The scaldback, Arnoglossus kessleri, is a small fish that belongs to the Bothidae family and its biology is unknown in the Mediterranean Sea including Aegean Sea, Black Sea and Sea of Marmara. To describe first information on the seasonal von Bertalanffy growth function parameters (SVBGF) using length frequency data for A. kessleri, and also to present first information on indirect methods to estimate natural (M) and total mortality rates (Z), a total of 12 months samplings were conducted between December 2012 and November 2013 in the south-east Black Sea. The overall sex ratio of females: males skewed towards males (χ2, P 〈 0.01). The SVBGF parameters, computed from monthly length frequency distribution analysis (LFDA), were estimated as L∞ = 8.25 cm total length (TL), K = 0. 549 year-1 for females and as L∞ = 8.44 cm TL, K = 0.490 year-1 for males. The seasonal oscillation in growth rate for females (C = 0.340) was larger than it was for males (C = 0.260). The slowest period of growth corresponded to December both females and males. The seasonal growth of the scaldback was most probably initiated by photoperiod and accelerated with decreasing water temperatures. Total instantaneous mortality rate, Z, was estimated as 0.853 yr-1 for females and 0.774 yr-1 for males. Instantaneous natural mortality ratio, M, was estimated a bit higher for females (M = 0.714±0.129) than for males (M = 0.655±0.098). The exploitation rate, E, of both sexes was also lower than the optimum exploitation (E = 0.5) criterion, which is indicative of non-exploited and/or lightly exploited of A. kessleri population. The results of this study were offered as biological input parameters for management of Black Sea stocks of the scaldback species.

    Description: The present study aimed to determine the concentration of metals in the soft tissue of wild mussels in coastal of Samsun and to assess human consumption. Using inductively coupled plasma mass spectrometry, the quantities of cadmium, mercury, lead, copper, iron, and zinc in Mytilus galloprovincialis were measured. The heavy metals found in Mediterranean mussels are arranged in the following ascending order: Cd 〈 Hg 〈 Pb 〈 Cu 〈 Fe 〈 Zn. Concentrations of toxic metals were safe according to European Commission guidelines and the Ministry of Agriculture, Forestry and Fisheries. According to the estimated daily intake (EDI), eating Mediterranean mussels poses no risks. The target hazard quotients (THQs) in metals are also found 〈1, which implies no threat to consumers. In conclusion, the current study confirmed that the concentration of heavy metals in the Mediterranean mussels is safe for people intake in terms of their toxicity.

    Description: This paper presents the results of the investigation of the dynamics of the main hydrochemical characteristics of the Azov Sea in the autumn seasons of 2021–2022. Over this time range, a change in the oxygen regime of the Azov Sea has been recorded. The concentrations of ammonium, nitrate, and total nitrogen, as well as total phosphorus have a considerable impact on the level of primary production of organic matter by phytoplankton. At the present period of a low river flow, the concentration of biogenic elements is decreasing, which leads to a decrease in the primary production of organic matter.
    Description: В работе представлены результаты исследования динамики основных гидрохимических характеристик Азовского моря в осенний период 2021–2022 гг. Отмечено изменение кислородного режима Азовского моря в исследуемый период. Концентрации аммонийного, нитратного, а также общего азота и фосфора в Азовском море оказывают существенное влияние на уровень первичного продуцирования органического вещества фитопланктоном. В современный период низкого уровня речного стока концентрация биогенных веществ уменьшается, что приводит к снижению первичного продуцирования органического вещества.

    Description: The nonlinear tide-surge interaction (NTSI) can significantly affect the levels associated with storm surges that threaten coastal areas. In this work, water level observations and numerical simulations are used to investigate those interactions in the large, mighty and socio-economically important Río de la Plata (RdP) estuary. We introduce a novel objective approach to seek evidence of nonlinear interactions in hourly water level records from six tide gauges collected along the coast. Results indicate that NTSI occurs in the RdP and suggest that it becomes more important upstream and along the southern coast of the estuary. CROCO ocean numerical model is used to quantify the interactions, to determine the areas where they are stronger, and to identify their sources. The amplitude of the interaction accounts for 16% of the total water level at the upper RdP, being comparable to tidal amplitude. The quadratic bottom friction is the principal cause of NTSI, and is modulated by the tidal current; therefore the nonlinearity is present all the time and is independent of the wind speed and direction. This is a particularity of this estuary and occurs because, as a consequence of its large width, surge currents are weak in spite of the big volume of water mobilized by the storms. Due to its nature, the interaction attenuates and smoothes the level anomalies due to the surge. Results highlight the need of utilizing a complete NTSI model for the forecast of the surge in the RdP; otherwise, the estuarine dynamic would be misrepresented generating significant forecasts errors (10%–20% at the upper RdP).

    Description: The contamination with trace metals brought on by anthropogenic activity is one of the main issues impacting the health of the environment. The inherent pressures on marine ecosystems and the individuals who depend on marine ecosystems for nourishment, industry, and advantage are both being seriously threatened by trace metal pollution in coastal and marine habitats. This study aimed to find out the accumulation of metals (Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb and Zn) in seasonal water samples taken for a year from the Ceyhan River's discharge point into the Northeast Mediterranean. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) measurements of water were performed using an appropriate trace metal-based approach. The relative mean metal concentrations in the water column were in the following order at the sample site: Zn 〉 Fe 〉 Ni 〉 Cr 〉 Cu 〉 Pb〉 Mn 〉 Cd 〉 Co 〉 Hg. The highest value of Zn in the water column was observed at 90.05810.605 g L-1. The levels of contaminants in the water when compared to international and national water quality standards have been judged to be within the safe drinking range.

    Description: Foraminifera is an important group of organisms which is widely used as indicators of environmental change. Not much work on foraminifera has been done on the Arabian margin running along the Pakistan coast. Information on the diversity and distribution of foraminifera is very limited and no information is available from the Balochistan coast. This study is an attempt to explore the diversity and dynamics related to foraminifera at the coast of Baluchistan. This very part of the study is designed to collect information about the zonation, vertical distribution and abundance of the genus Asterigerina at the beach of Ormara, Balochistan. The fossilized form of Asterigerina was previously reported from the sediments of upper Quetta region. This is the first report on the occurrence of alive Asterigerina in the coastal areas of Pakistan.
