Processed physical properties measured on sediment core GeoB19961-1
No full textSound knowledge about the petrophysical characteristics of a sediment core is a prerequisite for any subsequent paleoenvironmental study relying on sediment proxies. Physical properties of whole-round sediment cores are acquired as a first step of sediment core description, prior to slicing of sediment cores into two halves. Here, we present processed physical-properties data of core GeoB19961-1 acquired with a Geotek MSCL-S system on the unsplit core, retrieved during RV Maria S. Merian expedition MSM44 to West Greenland/Baffin Bay in summer 2015. Cores were processed according to the standard protocol given by the manufacturer Geotek Ltd

Dissolved rare earth elements, shale-normalized patterns, biogeochemical parameters, and indices from molecular analysis of dissolved organic matter across the land-ocean continuum in the German Bight
No full textWe analyzed concentrations of dissolved rare earth elements (REE) across the land-ocean continuum in the German Bight (southern North Sea) to identify key drivers for REE cycling in dynamic coastal environments. We identified the coastal transition zone as a critical interface for altering predominantly riverine-derived natural and anthropogenic REEs. We combined shale-normalized REE patterns, measured by quadrupole inductively coupled plasma-mass spectrometry (Q-ICP-MS), with biogeochemical bulk parameters and molecular analysis of dissolved organic matter (DOM) determined by ultrahigh-resolution mass spectrometry (FT-ICR-MS). Samples were acquired during RV Heincke cruise HE527. The dataset includes spatially resolved biogeochemical data (concentrations of chlorophyll-a, dissolved nitrogen, dissolved organic carbon, suspended particulate matter, dissolved iron, dissolved manganese and dissolved REE) in surface waters obtained along the major estuarine transects (Ems, Weser, and Elbe), coast-orthogonal transects and an offshore North Sea transect, with additional deep-water samples. Temporally resolved data were collected near the barrier islands Langeoog and Spiekeroog including the Otzumer Balje inlet. The dataset also contains molecular indices based on DOM composition (see Speidel et al., 2024) REE subgroups, ratios and concentrations of anthropogenic Samarium and Gadolinium (for details see Mori et al., 2025)
Bulk organic geochemistry (TOC, TN, d13C, d15N) of 61 surface soil samples from Chilean Patagonia
No full textThis dataset presents bulk organic geochemical data (TOC, TN, d13C, d15N) obtained by EA-IRMS analysis on 61 surface soil samples from Chilean Patagonia (44-48⁰S). The samples were collected in 2009 and 2013. They were obtained with a metal trowel in the epipedon, i.e., upper 10 cm of soil profiles, generally in road cuts, river cuts, or recent quarries. They were dry-sieved <90 µm before analysis. These soils constitute one of the most important sources of biospheric organic carbon to the Patagonian fjords. The elemental and isotopic measurements were used to (a) assess the influence of precipitation on organic carbon content and stable isotopes, and (b) characterize the composition of this biospheric organic carbon source to the Patagonian fjords
Raw physical properties measured on sediment core GeoB19961-3

Physical properties of whole-round sediment cores are acquired as a first step of sediment core description, prior to slicing of sediment cores into two halves. Here, we present raw physical-properties data of core GeoB19961-3 acquired with a Geotek MSCL-S system on the unsplit core, retrieved during RV Maria S.

Bulk organic geochemistry (TOC, TN, d13C, d15N) of sediment grain-size fractions from rivers in Chilean Patagonia
No full textThis dataset presents bulk organic geochemical data (TOC, TN, d13C, d15N) obtained by EA-IRMS analysis on sediment grain-size fractions from 6 rivers in Chilean Patagonia (n=75). The samples were separated in 10 to 12 grain-size fractions below 1000 µm to assess the influence of grain-size on river sediment geochemistry. Separation was made following the phi scale, using dry sieving for the particles coarser than 32 µm and an Atterberg sedimentation column for the <32 µm fractions. A sub-sample was also dry-sieved at 90 µm
Body measurements of Merlangius merlangus during Alkor cruise AL614
No full textThis data set includes single fish whiting data collected during the RV ALKOR cruise AL614 cruise conducted in June 2024 (6th to 15th of June) in the Western Baltic Sea by the University of Hamburg. The cruise was part of the 5-year MARSYS teaching cruise program of the University of Hamburg GFP20-1_047. The cruises are designed to train students in sampling methods targeting the different compartments of a marine ecosystem. All single fish measurements were made directly on board. Full wet weights of whitings were measured. Subsequently, whitings were gutted and liver weights, gonad weights and sexes, gutted wet weights (i.e., gutted wet mass), gonad stages and liver nematode infestations were recorded
Oceanographic data of Time Series Station Spiekeroog for 2023
No full textThe Time Series Station Spiekeroog (TSS) was setup in 2002, in the tidal inlet between the East Frisian Islands of Langeoog and Spiekeroog in the Southern German Bight, at position 53°45′01.0″ N, 007°40′16.3″ E. The aim was to ensure the continuous measurement of physical, biological, chemical and meteorological parameters, even under extreme weather conditions such as storms, ice, and storm surges. The TSS was financed as part of the Deutsche Forschungsgemeinschaft (DFG) research unit BioGeoChemistry of Tidal Flats and the Ministry for Science and Culture of the Land of Lower Saxony (MWK).
Here, sea level, water temperature and conductivity were measured in the year 2023. All raw data were revised and corrected for steps as range, outliers and stationarity checks. Water temperature and conductivity were measured in five different depths (4 m, 5.5 m, 7.5 m, 9.5 m, 11.5 m below MSL). Due to marine biofouling at the sensors and accompanying drift of instruments, the measured water temperature and conductivity data were corrected via linear regression by using reference data. As the water column in this region is well mixed and the water depth of the measurements varies with the tide, data from all five depths were averaged and referenced to a water depth of 4 m. Absolute salinity was derived from conductivity, temperature and pressure data according to TEOS 10. Data were smoothed and a quality flag was assigned for water temperature and salinity. The quality flags refer to the standard for data quality control of SeaDataNet https://www.seadatanet.org/ (0 = raw data, 1 = good data, 2 = probably good data, 3 = questionable data). A detailed description of the Time Series Station Spiekeroog, its structure and instrumentation can be found in Zielinski et al. (2022) and in Reuter et al. (2009)

Line scan images of IODP Hole 386-M0082C
No full textCollection of line scan images from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The offshore phase of this expedition took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. Images were obtained during the onshore phase of the expedition, which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu. After longitudinal splitting high-resolution (100 pixels/cm) images of each core sections archive half was captured using the Tri-Sensor Core Logger (TSCL; NS Design). The camera provides a 16-bit red-green-blue color (48-bit) TIFF file, which were converted to JPG files for publication purposes. The RGB data derived from each image for each section are published under titles "Color data (RGB) of IODP Hole 386-M0082C".
