    Description: 〈jats:title〉Abstract〈/jats:title〉 〈jats:p〉This study quantifies the state-of-the-art in the rapidly growing field of seasonal Arctic sea ice prediction. A novel multi-model dataset of retrospective seasonal predictions of September Arctic sea ice is created and analyzed, consisting of community contributions from 17 statistical models and 17 dynamical models. Prediction skill is compared over the period 2001–2020 for predictions of Pan-Arctic sea ice extent (SIE), regional SIE, and local sea ice concentration (SIC) initialized on June 1, July 1, August 1, and September 1. This diverse set of statistical and dynamical models can individually predict linearly detrended Pan-Arctic SIE anomalies with skill, and a multi-model median prediction has correlation coefficients of 0.79, 0.86, 0.92, and 0.99 at these respective initialization times. Regional SIE predictions have similar skill to Pan-Arctic predictions in the Alaskan and Siberian regions, whereas regional skill is lower in the Canadian, Atlantic, and Central Arctic sectors. The skill of dynamical and statistical models is generally comparable for Pan-Arctic SIE, whereas dynamical models outperform their statistical counterparts for regional and local predictions. The prediction systems are found to provide the most value added relative to basic reference forecasts in the extreme SIE years of 1996, 2007, and 2012. SIE prediction errors do not show clear trends over time, suggesting that there has been minimal change in inherent sea ice predictability over the satellite era. Overall, this study demonstrates that there are bright prospects for skillful operational predictions of September sea ice at least three months in advance.〈/jats:p〉

    Description: Water quality is one of several aspects that affect the success of aquaculture business. This study analyzes water quality and assesses its impact on aquaculture enterprises in the Rancong pond region of Lhokseumawe City. The study ran from November to December 2018. The water quality of the Rancong pond was sampled directly and tested in multiple labs. The field survey and purposive sampling strategy separated the research location into four stations with three water sampling points. Temperature, salinity, turbidity, brightness, pH, dissolved oxygen, alkalinity, total organic matter, BOD5, total ammonia nitrogen, nitrite, nitrate, phosphate, lead (Pb), total Vibrio bacteria, total general bacteria, and phytoplankton types and abundance were measured. The suitability of water quality is assessed using descriptive analysis, scoring, and matching. The investigation indicates that the quality and maintenance of the source water are highly suitable (S1). Traditional vannamei shrimp ponds in Rancong, Lhokseumawe City, should be maintained as fisheries cultivation areas.

    Description: Integrated Multitrophic Aquaculture System (IMTA) is a sustainable approach to aquaculture, utilizing ecosystem dynamics by integrating various species. This study examined the growth and survival of milkfish (Chanos chanos), tiger shrimp (Penaeus monodon), and oysters (Crassostrea spp.) in IMTA systems with different stocking densities. A 30-day experiment using a nonfactorial-completely randomized design with four treatments and three replications was conducted. The results showed that the implementation of IMTA had no significant impact on the survival rate of milkfish, tiger prawns or oysters in all treatments. However, important variations in growth parameters were observed. Milkfish and tiger prawns showed the highest weight and length gain in treatment B, followed by treatments A, C, and D. Similarly, oysters showed optimal growth in treatment B, followed by A, C, and D, based on weight gain, length, width, and shell thickness. Throughout the study, the physicochemical parameters of the water remained within acceptable ranges, thus supporting ideal growth conditions for the cultured species. These findings underscore the potential of IMTA to increase aquaculture productivity while upholding the principles of environmental sustainability. By optimizing stocking density and encouraging species diversity, IMTA presents a promising avenue for advancing integrated aquaculture practices, in line with the FAO's blue economy concept and ecosystem approach to aquaculture. Future research should concentrate on refining the IMTA system and evaluating its long-term ecological and economic consequences.

    Description: The most crucial aspect of managing an ecosystem or habitat is knowledge about accompanying biota, such as snails. The research on mangrove snails in the KPH Region III Aceh City of Langsa area was conducted in November 2021 with the goal of evaluating species diversity, density, ecological index, distribution, and their link to surrounding environmental conditions. Snail data was obtained via quadrat transects, with observation stations established using purposive sampling.The snail diversity was found to be five species from four families, with the highest density found in N. planospira (03.13 ind/m2). The diversity index was low (H' ≤ 2.0), dominance was moderate (0.5 〈 C ≤ 0.75), and uniformity tended to be balanced (0.5 〈 E ≤ 0.75). The distribution pattern is clustered (Iδ〉 1), with C. cingulata being abundant (83.33%), and C. capucinus being frequently found (50.00%), N. planospiraonly found occasionally (36.11%), and L. scabra and T. telescopium are relatively uncommon (11.11% and 0.56%, respectively), with a link to environmental variables indicating that T. telescopium prefers fine mud substrates. Meanwhile, C. cingulata, C. capucinus, L. scabra, and N. planospiralive in habitats with fine mud substrates that are more solid than T. telescopium’s habitats.

    Description: A revaluation of the relative sea-level (RSL) indicators in the Baia di Infreschi (Cilento, Southern Italy) supported by new 30 U/Th dating on speleothems indicates that the upper level of Lithophaga burrows identified by Bini et al. (2020) at ~9 m a.s.l. and correlated to the Last Interglacial (LIG) highstand should be referred to the highstand of the MIS 9e, whereas the local RSL for the highstand of the LIG is now reassessed at 5.3 ± 0.18 m a.s.l. The upper level of the Lithophaga marker can be followed for ~12 km along the coast, suggesting a substantial absence of important relative tectonic movements. In the Baia di Infreschi an additional marine indicator, a notch sealed by a flowstone dated ~110 ka, indicates several phases of RSL stationing below the maximum highstand of the LIG. The presence of flowstones as low as 2 m a.s.l. dated to the MIS 7 shows that the highstand of MIS 7 was probably below the present sea level. All these evidences allow us to reassess the stratigraphy of some archaeological caves in the area, indicating that the sedimentary successions preserved there are older than what was previously believed.

    Description: In this deliverable we describe the development of procedures and activities finalized to improve the communication between scientists and decision makers. In particular, trough testing and enhancing communication efficacy of scientific outputs, as maps, taking into account opinions and needs of the different stakeholders, in order to contribute in filling the gap between scientists and decision-makers. The selected pilot area has been Campi Flegrei active caldera, and outcomes from an Evaluation/Validation process on hazard tools as maps, involving local decision makers, will be presented. A similar evaluation procedure was applied for the tool BET_VH_ST developed as WP6 D6.2 for the short-term probabilistic volcanic hazard assessment. This tool has been implemented to compute hazard curves, hazard maps and probability maps for tephra fallout from Campi Flegrei. In order to finalize a specific requirement of the WP6TASK3, to contribute in sharing procedure and guidelines able to clarify role of scientists and decision maker and above to acquire a better comprehension of “end user’s view respect volcanic hazard assessment and related scientific tools, a specific questionnaire developed in the VUELCO project (Volcanic Unrest in Europe and Latin America) has been proposed to Sicily Civil Protection. A sample among Civil protection officials has been chosen including the ones having decision-making responsibility in case of volcanic unrest at Etna and Stromboli, to survey their opinions and requirements also in case of volcanic unrest, useful to finalize shared procedure and protocols. Furthermore according with sub task6.3.1 and in collaboration with WP7, a survey on volcanic risk perception at Azores involving civil protection officials and operators was carried out.

    Description: Earth System Literacy offers a rich matrix of narratives about (planet) Earth, World and Humans when interwoven with cultural artefacts (e.g. arts, history). Anthropogenic global change locks them together in a unifying framework. By making a distinction between reproduction, work (ergon, Greek) and civicness, there are narratives that convey what characterises the human condition today, including the material, social and historic settings of the Anthropocene.

    Description: A new species, Rubus ramachandrae, from Upper Subansiri district of Arunachal Pradesh, India is described and illustrated. It is closely similar to R. stipulosus and R. fuscifolius but differs by densely bristly or hirsute branches; narrowly ovate or oblong-lanceolate leaves with caudate-acuminate apex and adaxially hirsutulous vesture; abaxially grey tomentose intermixed with hirsutulous hairs; larger size of stipules and bracts with distinct margin and vesture; smaller size of floral structure. The distinct foliar as well as floral morphology of R. ramachandrae differs from all previously described species of Rubus. Differences in key morphological characters of R. ramachandrae, R. stipulosus and R. fuscifolius are also tabulated. In addition, pollen morphology is described based on light (LM) and scanning electron (SEM) microscopy. Based on the presence of straggling shrubby habit, free stipules, simple leaves, reflexed and strong needle shaped prickles, the new taxon is assigned to Rubus subg. Malachobatus. An image of the type specimen; digital images of habit, stipule, inflorescence and flower, a detailed illustration and scanned electron microscope images of pollens are provided.
