title: Concentrations and stable C and H isotopic compositions of methane in sediment core GeoB24302-2 from the Calabrian accretionary wedge, RV Sonne cruise SO278

description: Shallow sediment cores were collected with a gravity corer and a multi corer from several sites at the Sartori Mud Volcano in the Calabrian accretionary prism during cruise SO278 with R/V SONNE. In order to determine ex-situ concentrations and stable C and H isotopic compositions of methane dissolved in pore water, sediment samples were taken from the sediment cores with cut-off syringes and transferred into glass vials. Methane concentrations in the headspace gas were determined by use of gas chromatography (GC) and used to calculate concentrations of methane dissolved in pore water (uncorrected for sediment porosity and Bunsen coefficient). Stable C and H isotopic compositions of methane were determined by use of GC-isotope ratio mass spectrometry.

title: Chloride and sulfate concentrations of sediment core GeoB24302-2

description: Here we present pore water chloride and sulfate concentrations of several gravity and multi cores measured during R/V Sonne cruise SO278 at Sartori Mud Volcano (Calabrian Arc, Mediterranean Sea) to investigate the mud volcanic activity in more detail. Pore water was extracted ex-situ from selected sediment depths on whole round plastic liners using disposable syringes and rhizon samplers. Sampling interval for pore water measurements of chloride and sulfate ranges from 5 cm (MUC cores) to 10 cm (GC cores). The untreated pore water samples of filtered and unacidified aliquots were stored at 4°C until analysis. Concentrations of chloride and sulfate were analyzed by ion chromatography (IC) using a Metrohm 882 Compact Ion Chromatograph with an 858 Professional Sample Processor at MARUM.

title: Sediment core description of GeoB24302-2 recovered during R/V Sonne expedition SO278 at Sartori MV in the Calabrian Arc, Mediterranean Sea

description: Sediment cores were collected with a gravity corer and a multi corer from several sites at the Sartori Mud Volcano in the Calabrian accretionary prism (Mediterranean Sea) during R/V Sonne expedition SO278. Here we present core descriptions of GeoB24302-2 (GC01). To capture the sedimentary structure, gravity cores were longitudinally split directly after recovery on board of cruise SO278 and the archive halves were photographed using the smartCIS1600 line scan technique of the MARUM GeoB Core repository at a 500-dpi resolution. To investigate lithological changes in more detail, macroscopic core descriptions are prepared for all cores. The core descriptions provide information about core length, position, water depth, core sections, core image, color, lithology, sedimentary structures and a descriptive text. Sediment color was determined qualitatively using Munsell soil color charts.

title: Seawater carbonate chemistry and distribution of coastal benthic foraminifera

description: Coastal ecosystems are subjected to both large natural variability and increasing anthropogenic impact on environmental parameters such as changes in salinity, temperature, and pH. This study documents the distribution of living benthic foraminifera under the influence of multiple environmental stressors in the Skagerrak-Baltic Sea region. Sediment core tops were studied at five sites along a transect from the Skagerrak to the Baltic Sea, with strong environmental gradients, especially in terms of salinity, pH, calcium carbonate saturation and dissolved oxygen concentration in the bottom water and pore water. We found that living foraminiferal densities and species richness were higher at the Skagerrak station, where the general living conditions were relatively beneficial for Foraminifera, with higher salinity and Ωcalc in the water column and higher pH and oxygen concentration in the bottom and pore water. The most common species reported at each station reflect the differences in the environmental conditions between the stations. The dominant species were Cassidulina laevigata and Hyalinea balthica in the Skagerrak, Stainforthia fusiformis, Nonionella aff. stella and Nonionoides turgida in the Kattegat and N. aff. stella and Nonionellina labradorica in the Öresund. The most adverse conditions, such as low salinity, low Ωcalc, low dissolved oxygen concentrations and low pH, were noted at the Baltic Sea stations, where the calcareous tests of the dominant living taxa Ammonia spp. and Elphidium spp. were partially to completely dissolved, probably due to a combination of different stressors affecting the required energy for biomineralization. Even though Foraminifera are able to live in extremely varying environmental conditions, the present results suggest that the benthic coastal ecosystems in the studied region, which are apparently affected by an increase in the range of environmental variability, will probably be even more influenced by a future increase in anthropogenic impacts, including coastal ocean acidification and deoxygenation.
description: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2022) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2023-05-08.

title: X-ray fluorescence (XRF) data of sediment core GeoB24351-1, 50 kV run

description: X-Ray fluorescence (XRF) scans were carried out for core GeoB24351-1 (Gelendzhik MV; 0-284 cm) in 10 mm steps downcore on the split core surface of the archive half with the XRF Core Scanner III (AVAATECH Serial No. 12) at MARUM – Center for Marine Environmental Sciences in Bremen. To avoid contamination of the XRF measurement unit and the desiccation of the sediment, the split core was covered with a 4 µm thin SPEXCerti Ultralene1 foil. Reported data was acquired with a SGX Sensortech Silicon drift detector (Modul S SiriusD®D65133Be-INF with 133 eV X-ray resolution), a Topaz-X High-Resolution Digital MCA, and an Oxford Instruments 100 W Neptune X-Ray tube with rhodium (Rh) target material. Data were obtained during three runs at 50 kV (1st run), 30 kV (2nd run) and 10 kV (3rd run). Processing of raw data took place by the analysis of X-ray spectra by an iterative least square software package from Canberra Eurisys (WIN AXIL).
