    Zoobenthos and sediments time series at List Reede, Sylt, Germany, 2003 to 2019 (2022)

    Details
    Publication Date: 2023-03-16
    Description: A shallow subtidal area in the northern Wadden Sea was monitored over 17 years for sediment parameters and macrobenthic fauna using stratified random sampling of a grid of 50 sampling positions. Samples were collected with a Reineck-type box-corer of 0.02 m² surface area, always during preceeded high tide. Granulometric sediment composition was analysed from a sub-sample of each box-core using a diffraction laser particle-size analyser. Macrobenthos (sieved through 1 mm square meshes and fixed in buffered formalin solution) was counted, identified to species level, and the size of hard-shelled individuals measured. The amount of shell detritus was quantified as wet-weight in the benthos samples. From 2003 to 2007 sampling was approximatively monthly and from 2008 to 2013 seasonally. When a new ship with larger drought was put into operation, the number of sampling sites needed to be reduced to 33 from 2014 onwards and sampling frequency was only once per year in autumn.

    Description: Offshore wind energy is a steadily growing sector contributing to the worldwide energy production. The impact of these offshore constructions on the marine environment, however, remains unclear in many aspects. In fact, little is known about potential emissions from corrosion protection systems such as organic coatings or galvanic anodes composed of Al and Zn alloys, used to protect offshore structures. In order to assess potential chemical emissions from offshore wind farms and their impact on the marine environment water and sediment samples were taken in the surroundings of offshore wind farms of the German Bight between 25.07.2016 and 02.08.2016. At every sampling station oceanographic parameters were measured directly on board with respective probes of a multimeter covering pH, dissolved oxygen, temperature and conductivity.

    Stable oxygen and carbon isotopes of planktic and benthic foraminifera from the Lardos SW hill section, Rhodes, Greece (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-13
    Description: Stable oxygen and carbon isotopes were measured on (i) the planktic foraminifera species Globigerinoides ruber (white) and alternatively, in samples in which G. ruber was lacking, on Globigerinoides conglobatus; and (ii) the benthic foraminifera species Cibicidoides pachyderma and alternatively, in samples in which C. pachyderma was lacking, on Cibicides lobatulus. 10–15 planktic and 4-6 benthic specimens of the fraction 〉250 μm were selected. Additionally, attention was paid to select specimens of similar size to minimise influences of metabolic effects and changing preferential habitats during ontogeny. For cleaning and removal of sediment, the selected foraminifera were cracked between two glass plates, transferred to a sample cup, covered with ethanol and immerged into an ultrasonic bath for 5–10 s. The sediment brought into suspension was decanted. The procedure was repeated until the ethanol remained clear after the ultrasonic bath. The cleaned foraminifera were reacted with 100% phosphoric acidat 75 °C using a Kiel III online carbonate preparation line connected to a ThermoFinnigan 252 mass spectrometer (Geochemical Laboratory of the GeoZentrum Nordbayern,Germany). Isotopic data are expressed in per mil relative to V-PDB by assigning a δ18O-value of -2.20 ‰ to NBS19, using the standard δ-notation. The reproducibility was checked by replicate analysis of laboratory standards and was found to be better than ±0.05 for δ18O and δ13C (1σ).

    Physicochemical parameters of the water column for the sample stations of the Weser river campaign 2016 (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-14
    Description: A key task in understanding and mapping the complex mass transport pathways and potential transformation processes of contaminants in coastal regions such as the German Bight is to determine and evaluate the most significant contribution sources into coastal areas. Rivers represent one key input source within this context. As part of a river campaign in June 2016, sediment and freshwater samples were taken from the Weser river and its tributaries to identify their elemental and isotopic fingerprint and to investigate potential inputs to the German Bight. At every sampling station physicochemical parameters of the water column were measured directly after sampling with respective probes of a multimeter covering pH, dissolved oxygen, temperature and conductivity.

    Description: In order to understand and map the complex mass transport pathways and possible transformation processes of contaminants in coastal regions such as the German Bight, the main coastal contributors must be identified and evaluated. In this context, rivers represent a major input source. In the framework of a river campaign from 20.06.16 till 25.06.2016, sediment and freshwater samples of the Ems and its tributaries were taken to determine their elemental and isotopic fingerprint and to investigate possible inputs into the German Bight. All sediment samples were obtained using a Van Veen grab sampler and were analyzed for their grain size distribution by laser diffraction.

    Whale sightings during POLARSTERN cruise PS89 (ANT-XXX/2) (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-16
    Description: Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS89 (Cape Town – Cape Town) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a “certainty” level of identification. The number of animals were counted if possible or estimated for larger groups. Whenever identification to species level was not possible, the next identifiable taxonomical category was assigned. Information on sighting position, date and time are automatically transferred from the ship's DAVIS-Ship System (https://dship.awi.de/) to the WALOG software at the time of logging. Photographs were taken if possible for retrospective analysis. All data of acquired sightings were retrospectively validated by a marine biologist and converted to a standard format. To this end, plausibility of sighting time, location, standardization of species names, eventual comments added at the time of sighting, as well as additional information such as photographs (if available) were checked either to verify or improve species identification. Datasets are used in species distribution modelling and to inform interested parties about occurrences.

    Whale sightings durin POLARSTERN cruise PS88.1 (ANT-XXX/1.1) (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-16
    Description: Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS88.1 (Bremerhaven – Las Palmas) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a “certainty” level of identification. The number of animals were counted if possible or estimated for larger groups. Whenever identification to species level was not possible, the next identifiable taxonomical category was assigned. Information on sighting position, date and time are automatically transferred from the ship's DAVIS-Ship System (https://dship.awi.de/) to the WALOG software at the time of logging. Photographs were taken if possible for retrospective analysis. All data of acquired sightings were retrospectively validated by a marine biologist and converted to a standard format. To this end, plausibility of sighting time, location, standardization of species names, eventual comments added at the time of sighting, as well as additional information such as photographs (if available) were checked either to verify or improve species identification. Datasets are used in species distribution modelling and to inform interested parties about occurrences.

    Description: A total of 125 aerosol samples were analysed for their lithium concentrations and deposition flux. Daily aerosol samples were collected from the Pacific Ocean during CLIVAR-CO2 Repeat Hydrography Sections P16 and P2. The P16 section follows 150°-152°W and was divided into two legs, a southern leg from 17°S to 71°S in January-February 2005, and a northern leg from 16°S to 56°N in February-March 2006. CLIVAR-CO2 section P2 from Japan to San Diego, along 30°N, was visited in June-August 2004. The aerosol data from both CLIVAR-CO2 sections include aerosol lithium concentration measured following digestion in HF:HNO3:HCl mixture and corrected for sea-salt contributions (Li xs total), the P16 data also includes aerosol lithium extracted with ultrapure deionised water (≥18 MΩ) by pulling 100 mL of deionised water within ten seconds through the filter (Li xs MQ). Aerosol lithium deposition flux was calculated based on the local rain rate.

    Physical properties of sediments in the Norwegian Trough measured on short cores taken between 1992 and 1996 (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-02
    Description: Wet bulk density, dry bulk density, porosity, water content and water saturation of sediments from the Norwegian Trough were determined on short cores taken between 1992 and 1996. On the cruises 17-25 July 1992 (station 2-55) and 1-6 July 1993 (station 56-75) in the easternmost part of the Skagerrak, cores were taken with a Niemistö corer. Plastic liners (length 76 cm, outer diameter 63 mm, inner diameter 59 mm) were placed in the corer with holes drilled every five centimetres downwards. These holes were sealed with tape before sampling. After the sample was taken, the tape was removed. In most cases, there was water along the inside of the plastic liner. This water was allowed to drain before sub-samples were taken. Then plastic syringes without a tip were carefully inserted into each hole, and 10 ml of wet sediment was taken out. The sub-samples were then pressed out of the syringes into plastic bags that had been weighed in advance and stored in a refrigerator until they were measured in the laboratory. Upon arrival at the laboratory, the plastic bags with samples were weighed, the weight of the plastic bags was deducted, and the weight of 10 ml of the wet sample was noted. The weight of the dry sample was found by transferring the sample material onto a pre-weighted ceramic bowl before it was weighed again, then drying the bowl with sample in drying cabinet at 70 degrees C for 24 hours, and finally weighing the bowl with sample after drying. The weight of 10 ml of dry sample corresponds to the difference before and after drying. On the cruises 5-16 June 1994 (stations 76-133), 17-24 July 1995 (stations 135-180) and 9-19 September 1996 (stations 181-286), cores were taken with a multicorer. Plastic liners (length 61 cm, outer diameter 63 mm, inner diameter 59 mm) were placed in the corer, which after sampling was closed at both ends with rubber caps to prevent water in the core and on top of the core from leaking out or to evaporate. The cores were then transported to the laboratory in an upright position and stored as such until they were opened. After removing the rubber cap on top of the core, the water was drained by drilling holes in the plastic liner just above the top of the sediment. Lying in a rack, the core was then divided lengthwise with a circular saw by sawing through the plastic liner on both sides of the core. A thin string was then pulled in the saw gap through the sediment and the core split in two halves. Metal rings of known weight and volume were used to take sub-samples. The ring (approx. 2 cm in diameter) was gently pressed into the sediment at certain depths in the middle of one of the core halves, until the ring was full, and then gently tilted out with a spatula. The ends were levelled with a wire saw or spatula, and the excess sediment was discarded. The wet sample plus ring was weighed immediately after the sediment on the outside of the metal ring was removed. The sample was then pressed out into a pre-weighed porcelain bowl. Then the weight of bowl plus wet sample was measured, and the weight of wet sample was determined. The sample was dried in a porcelain bowl in a heating cabinet at 105 degrees C for 24 hours, before the sample plus bowl was weighed again and the dry weight was determined. More details on the methods can be found in Rise and Bøe (1995) and Bøe and Rise (1997).

    Description: All sediments were freeze-dried and the porosity was determined from the weight loss upon freeze drying. To determine the total elemental concentrations of aluminum (Al), Co, Fe, Mn, Ni, and S, ca. 125 mg of sediment was digested in 2.5 ml mixed acid (HNO3:HClO4; 2:3) and 2.5 ml 40% HF at 90◦C. After fuming off the acids, the residue was redissolved in 4.5% HNO3. The solutions were subsequently analyzed on an ICP-OES. The analytical uncertainty based on duplicates and triplicates was 〈1% for Al, 〈4.2% for Co, 〈1.6% for Fe, 〈2.5% for Mn, 〈2.3% for Ni, and 〈1.7% for S. A subsample of circa 300 mg was decalcified with 2 wash steps of 1M HCl and subsequently dried, powdered and analyzed for carbon (C) using an elemental analyser (Fisons Instrumentsmodel NA 1500 NCS). Organic C content was determined after correction for the weight loss following decalcification. The analytical uncertainty based on duplicates and triplicates was 〈0.07 wt%.

    Description: Porewater samples for NH4+, NO3- , and NO2- were analyzed on board with Quattro gas-segmented continuous flow analysers using the indophenolblue method (NH+4), and the sulphanyl-amide method (NOx). Porewater sulfide was determined spectrophotometrically using phenylenediamine and ferric chloride. Porewater samples for SO4 2- were analyzed by ion-chromatography. Dissolved Fe and Mn were analyzed by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES; Spectro Arcos). Porewater concentrations were around or below the detection limit (0.5 and 0.8 μmol L−1, respectively) and are therefore not presented.

    Publication Date: 2023-03-13
    Description: The compound-specific hydrogen isotopic composition (δ2H) of n-alkanes well reflect hydrological conditions in lake sediments, but the spatial distribution of the δ2H signal of terrestrial and aquatic n - alkanes within lakes is not systematically investigated so far. Therefore, we analyzed compound-specific δ2H of terrestrial and aquatic n-alkanes of 46 surface sediment samples from Lake Khar Nuur, a semi-arid and high-altitude lake in the Mongolian Altai (2,486 m a.s.l.; 48°37'22.9N, 88°56'42.5E). Additionally, we analyzed the terrestrial δ2H signal of 13 topsoils from the catchment. Lake surface sediments were recovered from the lake floor with a Van Veen Grab sampler and topsoils (0-5 cm) were sampled as a mixed samples of three subsamples from each site during a fieldtrip in July 2018. Sample extraction procedure is described in detail by Strobel et al. (in revision). Compound-specific δ2H was analyzed for the terrestrial n-alkane C31 (δ2HC31) in the topsoil and surface sediment samples, whereas δ2H of the aquatic C23 (δ2HC23) was analyzed in the lake surface sediments. One topsoil site is grown by Betula nana (L.) showing C27 as the dominant chain-length, which was target for compound-specific δ2H measurements at this site (δ2HC27). All δ2H measurements were carried out on an IsoPrime visION isotope ratio mass spectrometer coupled to an Agilent 7890A GC via a GC5 pyrolysis/combustion interface operating in pyrolysis mode with a Cr (ChromeHD) reactor at 1050 °C.

    Details
    Publication Date: 2023-03-14
    Description: Here, we present 23 water physical (temperature, dissolved oxygen, pH, conductivity) and chemical (major anions Cl-, SO42-, CO32-, HCO3- and cations Ca2+, K+, Mg2+, Na+), sedimentological (total carbon (TC), total inorganic carbon (TIC), total organic carbon (TOC), total nitrogen (TN)), mineralogical (quartz, carbonate, phyllosilicates and feldspars) and geological (altitude, bedrock type and age of sediments) variables of aquatic systems of the Northern Neotropical region. Sampling was conducted in 76 aquatic systems during July-October 2013, coinciding with the rainy season in the region. Sampling sites are located on the Yucatán Peninsula Mexico (n=28), Guatemala (n=26), El Salvador (n=14), Honduras (n=5) and Nicaragua (n=3). We aim to identify limnological regions based on the measured variables and to infer the influence of geodiversity in observed patterns. Water physical and chemical variables were measured in situ with a WTW Multi Set 350i multiparameter probe at a water depth of 0.5 m. Water samples for analysis of major anions and cations were collected at water depths of 0.5 m below surface. TC and TN in sediments contents were determined by combustion with a LECO TruSpec Macro CHN analyzer. TIC was quantified with a Woesthoff Carmhograph C-16. TOC was calculated by subtracting TIC from TC. Qualitative and semi-quantitative mineralogical compounds were examined by x-ray diffraction with a RIGAKU Miniflex600. ArcGIS software was used to identify geological attributes of sampling sites such as bedrock and age of sediments. Altitude, latitude, and longitude were determined with the navigator Garmin GPSmap 60c.

    Boron, lithium and isotope compositions in acid-sulfate and black smoker fluids from Macauley and Brothers of SONNE cruise SO253 (South Pacific) (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-14
    Description: Lithium, boron and magnesium isotope compositions in high-temperature and acid-sulfate fluids from Brothers and Macauley volcano, Kermadec Arc, Western Pacific collected during SO-253 cruise. The acid-sulfate fluids exceed Mg concentrations of seawater and differ from previously known acid-sulfate fluids with seawater-like Mg concentrations. Based on our data, we explain the Mg enrichments with venting of a brine phase (Macauley volcano) and dissolution of caminite and Mg leaching from the ocean crust (Lower Cone, Brothers Volcano).

    Description: During two crusies in June (AL510) and September (AL516) 2018, a data set (N=76) from the sea surface microlayer (SML) was compiled in Eckernförde Bay, Germany. SML samples were collected with the glass plate technique. Reference samples from the underlying water (ULW) at an approx. depth of 20cm were collected with the help of a bottle. Total and dissolved hydrolysable amino acids, combined carbohydrates and dissolved organic carbon were analyzed to describe surfactant dynamics (based on phase-sensitive AC voltammetry). Flow cytometry provided additional information on bacteria and phytoplankton community composition. This data set resolves dynamics on short temporal (diurnal sampling ) and local scales (within an area of 50km^2).

    Publication Date: 2023-03-14
    Description: Offshore wind energy is a steadily growing sector contributing to the worldwide energy production. The impact of these offshore constructions on the marine environment, however, remains unclear in many aspects. In fact, little is known about potential emissions from corrosion protection systems such as organic coatings or galvanic anodes composed of Al and Zn alloys, used to protect offshore structures. In order to assess potential chemical emissions from offshore wind farms and their impact on the marine environment water and sediment samples were taken in the surrounding and within different wind farms of the German Bight in April 2018. At every sampling station oceanographic parameters were measured directly on board with respective probes of a multimeter for pH, dissolved oxygen, temperature and conductivity. Additionally, the current associated weather parameters (temperature in air, wind speed, air pressure) were noted from the ship system.

    Whale sightings during POLARSTERN cruise PS90 (ANT-XXX/3) (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-16
    Description: Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS90 (Cape Town – Bremerhaven) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a “certainty” level of identification. The number of animals were counted if possible or estimated for larger groups. Whenever identification to species level was not possible, the next identifiable taxonomical category was assigned. Information on sighting position, date and time are automatically transferred from the ship's DAVIS-Ship System (https://dship.awi.de/) to the WALOG software at the time of logging. Photographs were taken if possible for retrospective analysis. All data of acquired sightings were retrospectively validated by a marine biologist and converted to a standard format. To this end, plausibility of sighting time, location, standardization of species names, eventual comments added at the time of sighting, as well as additional information such as photographs (if available) were checked either to verify or improve species identification. Datasets are used in species distribution modelling and to inform interested parties about occurrences.

    Description: Radiocarbon ages measured on different sample types from the marine sediment core OR1-1218-C2-BC which was retrieved from the southern South China Sea using a box corer. Onboard the ship, the core was separated into several sub-cores of which nine sub-core were analysed. Bulk samples contain 1/3 of 200 individual foraminifera (~800 µg) picked from the nine sub-cores at discrete depths (0 - 2, 6 - 8, 10 - 12, 16 - 18, 22 - 24, 28 - 30 and 32 - 34 cm.). Additional small number samples are based on 5 specimens with ten replications for two depths (6 - 8 and 36 - 37 cm) from sub-core 1. The data are used to estimate the sediment accumulation rate and the vertical extent of the sediment mixing. Additionally, the data are used to assess the intensity of the sediment mixing and the three-dimensional age-heterogeneity within the core.

    Publication Date: 2023-04-08
    Description: The Last Interglacial (LIG, 129-116 thousand years ago) is an excellent case study for global warming scenarios and a target for proxy-model comparisons. The LIG global average sea surface temperature (SST) was ~0.5°C higher than pre-industrial (PI). Despite the global average, tropical SST compilations and model simulations show a negative anomaly in LIG SST relative to PI. Here, we present a LIG SST record from marine sediment core GL-1180 retrieved from the western tropical South Atlantic (WTSA). The SST record is based on Mg/Ca ratios of planktonic foraminifera Globigerinoides ruber (white).

    Details
    Publication Date: 2023-04-27
    Description: Borehole temperature measurements at site GeoB22605-1 were performed with the sea floor drill rig MARUM-MeBo200 during research expedition M142 in November 2017 at the Danube Deep Sea fan in the Black Sea. A platinum resistance sensor integrated in the 1343 Slimhole Memory Acoustic Tool developed by ANTARES Datasystems GmbH was used to measure the temperature of the fluid within the borehole with 103 mm diameter. The temperature range is –20 to +80 °C, the absolute accuracy within the limits of the measuring range is about 1 °C. The resolution of the temperature measurements is about 0.003 °C. Temperatures were logged with a frequency of 0.5 Hz by a memory adapter with an integrated clock that was synchronized with GPS-time. Borehole logging was conducted during trip out of the drill string. When the drilling operation was completed and the drill string was lifted by about 3.5 m the logging string was dropped into the drill string. After landing on the drill bit the logging string together with the drill string were tripped out of borehole. The depth control system of the drill rig was used to calculate the sensor depth with an accuracy of 0.1%.

    Description: The Benguela Upwelling System is situated between 18°S and 26°S and is characterized by seasonally variable upwelling cells, elevated surface primary and secondary productivity, high sedimentary organic carbon concentrations (up to 20 %), and locally stable bottom water anoxia. Between 2014 and 2019, surface sediment cores were collected, subsampled, and analysed using geochemical and sedimentological tools. For the grain size fractionation, a combined sieve-centrifuge-filtering approach was developed to create seven fractions (〉 250, 250-200, 200-125, 125-63, 63-10, 10-2, ≤ 2.0 µm) and the density fractionation followed a centrifugation sequence to yield four fractions using sodium polytungstate (NaW) heavy liquid (≤ 1.6, 1.6-2.0, 2.0-2.5, 〉 2.5 g cm-3) (cf., Wakeham et al., 2009, https://doi.org/10.1016/j.marchem.2009.08.005). The bulk surface sediment and each fraction were analysed for TOC (%), radiocarbon age (F14C), and surface area (m2 g-1). Together with literature data, these samples are used to test and illustrate a novel hypothesis on sediment hydrodynamic properties in oxygen-depleted environments.

    Water chemistry of a Lagrangian sampling of Inland Elbe 2020 (MOSES Hydrological Extremes) (2022)
    PANGAEA
    Details
    Publication Date: 2023-04-22
    Description: The MOSES test campaign ELBE 2020 includes activities along the middle reaches to the tidal Elbe river and the German Bight. The inland Elbe river part of the campaign covers physico-chemical parameters from various sites along the Elbe River and its main tributaries. The sampling was conducted in a Langrangian way according to travel time, particularly between Aug 04 to Aug 12. Discharge in Magdeburg was 241 m³/s which is about mean low discharge (231 m³/s). Physico-chemical parameters as well as nutrients were sampled using the research vessel ALBIS from Schmilka (km 4, German border) to Geestacht (km 585, close to Hamburg). The targets were water quality measurement by multiparameter probes and chemical analyses, the detection of phytoplankton growth and decrease of dissolved nutrients along the river.

    Soil organic carbon over 42 years of organic and conventional farming and biological soil quality in year 42 of the DOK long-term field experiment (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-27
    Description: The DOK trial in Therwil (CH), compares bioorganic (BIOORG), biodynamic (BIODYN) and integrated (CONFYM) farming systems at two farmyard manure intensities corresponding to 0.7 and 1.4 livestock units per hectare with a purely mineral fertilized system (CONMIN) and an unfertilized control (NOFERT) since 1978. The treatments differ in plant protection and receive farming system specific organic matter inputs differing in rate and quality. SOC contents increased in BIODYN 1.4, less in BIOORG 1.4, and were stable in CONFYM 1.4. Enhanced biological soil quality under organic and particularly biodynamic management highlights the immanent relation between soil biology and SOC changes. Systems fertilized with manure of 0.7 livestock units and CONMIN lost SOC, but loss was highest in NOFERT. The impact on soil quality was only detectable after 20 years of continuous management. We conclude that recycling of the manure from 1.4 livestock units per hectare allows to maintain SOC levels and that the investment in producing manure compost from the same number of livestock is needed to enhance SOC levels and improve biological soil quality. The data come from 96 field plots (8 farming systems, 3 subplots with crops from a temporally shifted 7-year crop rotation, 4 replicates). Soil organic carbon was analysed in archived samples from 0-20 cm every second year between 1982 and 2018. Soil quality as assessed by pH, SOC, Ntot, soil microbial biomass C and N, soil basal respiration and alkaline phosphatase activity was measured in the 42nd year of the trial in 0-20 cm samples taken in spring 2019.

    Radiolarian based subsurface temperatures in sediment core MD11-3353 (360kyrs record) (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-30
    Description: In the Southern Ocean (SO), climate-driven latitudinal migrations of the Antarctic Circumpolar Current (ACC) frontal system impact large-scale ocean circulation and primary productivity. Latitudinal migrations may not have been identical in all SO basins due to the presence or absence of regional bathymetric obstacles. The Antarctic Polar Front (APF), defined by the 3–5 ◦C surface temperature range and the 2 ◦C subsurface temperature minimum at 200 m, is particularly important for nutrient redistribution and biodiversity, influencing the soft tissue carbon pump in the modern SO. However, previous assessments of its migrations in the past, mostly based on a single metric or indirect observations, were not always robust. Here, we combine a new proxy for subsurface temperature (sub-ST) reconstructions based on radiolarian assemblages (sub-STrad), with relative abundance variations of key radiolarian species, and sea-surface temperatures (SST) reconstructions, based on diatom assemblages (SSTdiat), to refine estimations of the past mean APF locations in the Kerguelen Plateau (KP) region. Data from three sediment cores on a south (55◦S) to north (47◦S) transect are used to trace the mean APF locations for three climate states, glacials, peak-interglacials and mild-interglacials. Our results suggest that the APF, presently located south of Kerguelen Islands, shifted by 6–7 degrees of latitude and was located north of the KP during all glacial periods of the last 360 kyrs. This suggests that the ACC major flow interacted less with the bottom topography relative to its modern counterpart, probably resulting in less mixing of the water column over and in the lee of the KP. We propose that this process participated in the isolation of Antarctic surface waters (AASW) and in the reduction of macro-nutrient supply, thus resulting in lower regional productivity. During the warmer-than-present early interglacial periods, the APF probably migrated south by ~5 degrees of latitude relative to its modern position, to pass through the Fawn Trough. Contrary to glacial periods, the APF was forced in an “S” shape while the ACC main flow was constrained against the northern tip of the KP. In this configuration, a stronger interaction between the ACC, its associated fronts, and topography is expected, resulting in more mixing of the water column over and east of the KP. Congruently, siliceous productivity was probably restrained to latitudes south of the Fawn Trough.

    Details
    Publication Date: 2023-01-13
    Description: On the outward journey, European air masses, loaded by photochemically produced ozone, may have partly influenced the measurements in clean air. As simultaneously measured low concentrations of Krypton-85 (which only has anthropogenic sources) show, the high ozone mixing ratios at 0-5°N cannot be explained by photochemical formation, but must be of natural origin. On the return journey, the ITCZ was at 6°S and was weak. This explains the very low ozone values of only 4 ppb at times, caused by the photolysis of ozone. The ozone device was housed in the crow's nest, to avoid ship-polluted interference. At later cruises, the instrument was placed near the weather station, because the maintenance in the crow’s nest was impractical and the new air intake at the uppermost railing turned out to be suitable as well. As a precaution, the air pump was changed nine times during the trip. At the end of the last section, the pump wobbled a little, resulting in a five percent loss of production, which could be corrected

    Nitrogen turnover in the Ems estuary 2014 (2022)
    PANGAEA
    Details
    Publication Date: 2023-01-13
    Description: We measured dissolved and particular inorganic nitrogen concentrations in the Ems estuary (Germany). The sampling campaign was conducted on three days in August 2014 (05.08.2014– 07.08.2014) on board of the German research vessel Ludwig Prandtl. Water samples were taken regularly along the salinity gradient of the estuary irrespective of the state of the tide 2 m below the surface. For stations S276 to S280, only the Ferrybox measurements were taken 2 m below the surface. The water samples were taken by a Niskin-Bottle 2 m above the bottom. The water samples were filtered immediately and stored frozen for analysis of dissolved inorganic nutrient and nitrate stable isotope composition. Filtered samples for suspended particular matter (SPM) concentration, particular carbon and nitrogen content of SPM and nitrogen stable isotope composition of SPM were dried at 50°C and also stored frozen. An onboard membrane pump provided the on-line in situ FerryBox system with water from 2 m below the surface. It continuously measured oxygen, salinity, and temperature during our cruise. More information can be found in Sanders and Laanbroek (2018). The aims of the cruise were 1) to study spatial segregation of nitrogen turnover, 2) to identify the dominant nitrogen turnover processes in the water column and 3) to investigate controlling factors of the nitrogen cycle along the Ems estuary.

    Wet chemical surface ozone measurements during POLARSTERN cruise ANT-III/3 and ANT-III/4 (PS06) in 1985 (2022)
    PANGAEA
    Details
    Publication Date: 2023-01-13
    Description: On the outward journey of PS06 an ozone minimum was encountered at the ITCZ, as is typical for high levels of solar radiation and low vertical exchange. Under such conditions, ozone can be depleted by photolysis, but cannot be replaced due to weak vertical exchange. On the return voyage, two ozone peaks occurred at and north of the ITCZ. According to Class and Ballschmiter (1986) who measured some organic trace gases, the ITCZ consisted of two branches found at 2°S and 2°N. The noticeable ozone peaks may have been caused by strong vertical exchange, with ozone being mixed down from the upper troposphere. In some cases, clear daily variations were recorded during the journey.

    In-situ mineral, bulk sulfide-sulfate, S- and Pb isotope, and whole rock major and chalcophile element data from the submarine Niuatahi hydrothermal system, Lau basin, Tonga rear-arc (2022)
    PANGAEA
    Details
    Publication Date: 2023-01-13
    Description: The samples used in this study were recovered from active hydrothermal venting at the seafloor at the Niuatahi caldera, Lau basin, Tonga rear-arc, observed during research cruise SO263. The dataset was collected in order to define the magmatic and hydrothermal processes leading to spatially selective trace element enrichment within submarine caldera-hosted black smoker systems. The in-situ data was measured by electron probe micro analyzer and laser ablation inductively coupled mass spectrometry. The sulfur- and Pb isotope composition of hydrothermal sulfide separates were analysed by a Flash EA IsoLink elemental analyzer interfaced to a ThermoScientific Delta V Advantage isotope ratio mass spectrometer and a a Thermo-Fisher Neptune Plus multicollector inductively coupled mass spectrometer, respectively. Bulk sulfide-sulfate composition was determined by an Agilent 735 inductively coupled mass spectrometer, inductively coupled optical emission spectroscopy and instrumental neutron activation analysis. The whole rock/glass major and chalcophile element contents were measured by a Spectro XEPOS He-x-ray fluorescences spectrometer, a JEOL JXA-8200 Superprobe electron probe micro analyzer, a Thermo Fisher Scientific X-Series 2 quadrupole inductively coupled mass spectrometer, and a PSA Millenium Excalibur 10.055 continuous flow hydride-generation atomic fluorescence spectrometer. All analyses except the bulk sulfide-sulfate and S isotope measurements were carried out at the GeoZentrum Nordbayern, Friedrich-Alexander University, Germany, which were measured at Activation Labs in Ontario, Canada, and the Westfälische Wilhelms-University, Münster, Germany, respectively. The dataset gives a detailed insight into the magmatic and hydrothermal evolution and processes controlling seafloor black-smoker-style mineralization.

    Late Cretaceous cyclostratigraphy for the subtropical western South Atlantic, Espírito Santo Basin (2022)

    Details
    Publication Date: 2023-01-13
    Description: Well-log data was acquired in a Late Cretaceous section of the Espírito Santo basin (western South Atlantic). Cyclostratigraphic techniques were used to explore the eventual pacing of orbital cycles in the deposition of sequences. The frequency ratio method was used to interpret the orbital cycles and based on this a long-eccentricity signal was interpreted and extracted to create a floating time-scale. Using a seismic horizon associated Cretaceous-Paleogene transition, a strong shift in the natural gamma-ray data was anchored to an age of 66.0 Ma producing an anchored astronomical time-scale placed between late Albian and early Ypresian.
