title: Unfiltered snow surface height above sea level on station PS81/506_GPS1

description: Terrestrial laser scanning (TLS) was used to determine the snow surface height above sea level for an approximately 50x50m patch. The reference to sea level was obtained using registration targets drilled through the ice with a measured distance between the target and the water level in the drill holes.
description: Coordinates:============X and Y coordinates are relative to a GPS base station installed on each floe. Coordinates were determined using post-processing kinematic GPS (PPK-GPS), and corrected for floe ration and drift. Coordinates of measurements inside the laser scanning area were particularly carefully processed to collocate measurements as accurately as possible (within a few cm). The vertical height above sea level in the TLS data was determined by using reflectors on poles. Upon installation of these reflector poles, the ice was drilled through and the height of the reflector above sea level was determined. For details, see Wever et al. (2021).On the floe scale walk, magnaprobe coordinates have been equally processed as in the laser scanning area. However, for the GEM-2 instrument, the position of the magnaprobe was taken for the corresponding time stamp in the GEM-2 data. Since the GEM-2 instrument was following the Magnaprobe surveyor with a few m distance, this leads to less precise positioning. However, the GEM-2 instrument also has a footprint of similar order of magnitude (see Hunkeler et al., 2015).Coordinate reference points:============================All coordinates are relative to GPS base station 1, in a local coordinate system where X and Y coordinates align with easting and northing, respectively, from the respective UTM Zone at a specific point in time. The respective coordinates of GPS base station 1 for this dataset are:For PS81/506: Location of GPS base station 1, July 12 2013, 2000 UTC:WGS84 : latitude=-67.19689 longitude=-23.15692UTM Zone 27S : northing=2545052 easting=406729

title: Beryllium-7 concentrations in seawater during the MOSAiC expedition

description: Pumps were used to collect seawater within the upper 60 m of the ocean for Be-7analysis. Unfiltered seawater was drawn through a pvc hose to the surface where it was passed through iron-oxide impregnated acrylic fiber filters, which adsorb the Be-7. A flow meter attached in-line to the filter compartment recorded the amount of seawater passed through each filter. To maximize Be-7 collection, two or three fibers filtering approximately 600- 700 L of seawater apiece were collected from each depth and later combined. For the mixed layer samples, water was collected from the ship's seawater intake (~8m) into barrels from which the water was passed through the iron-oxide filters as described above. The fibers were dried and shipped to Florida International University. There, the fibers were ashed, placed in a Marinelli beaker and analyzed with a high purity germanium (HPGe) gamma detector. Be-7 has a readily identifiable gamma peak at 478 keV. The detector is calibrated by adding a commercially prepared mixed solution of known gamma activities to an ashed fiber and counting it in the Marinelli geometry.

title: Benthic foraminifera oxygen index of ODP Site 145-883

description: Here we present dissolved oxygen estimates from benthic foraminiferal assemblage data in discrete samples from ODP site 883. Benthic faunal assemblage data from Dowsett and Ishman (1995) were used to calculate dissolved oxygen using the enhanced benthic foraminiferal oxygen index of Kranner et al. (2022). Species and genera were classified as oxic, suboxic, or hypoxic indicators based on the Kranner et al. (2022) classification scheme. Where species counted by Dowsett and Ishman (1995) were not classified by Kranner et al. (2022) but other members of the same genera were, the classification of those catalogued species was used. Where genera counted by Dowsett and Ishman (1992) were not classified by Kranner et al. (2022) (e.g., Globoscassidulina subglobosa and Laticarinina pauperata), the classifications assigned by Kaiho et al. (1994) were used.

title: Annotated record of the detailed examination of Mn deposits from INDUSOM cruise stations (R/V Marion Dufresne)

description: The cores and dredges described at this site were taken on the INDUSOM cruise from 17 to 30 April 1985 by the Muséum National d'Histoire Naturelle from the R/V Marion Dufresne. A total of 22 cores were recovered and are available at MNHN for sampling and study.
description: From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

title: A one-year-long aerobic incubation experiment assessing CO₂ and CH₄ production in thermokarst terrain on the Barrow Peninsula, Arctic Alaska

description: During an expedition in April 2022, four sediment cores were taken from thermokarst terrain on the Barrow Peninsula (Alaska). In the subsequent laboratory experiment, wet sediment samples (15 g) were incubated for 382 days under aerobic conditions at 10 °C. Along the undisturbed tundra upland core, one sample was taken from the active layer and two samples from the permafrost domain. Since a short core from the talik was retrieved from West Twin Lake, one sample was chosen from this core. The East Twin Lake core was characterized by unfrozen cryotic conditions (cryopeg), from which three samples were selected along the core. From the drained lake basin core, two samples were taken from the active layer and one from the permafrost domain. Each of the ten incubation samples was divided into three replicates, resulting in a total of 30 samples. At day 0 of the experiment, all vials were flushed with synthetic air (20 % O2, 80 % N2). CO2 and CH4 concentrations were measured three times per week during the first two weeks, two times per week from week 3 to 7, one time per week from week 8 to 15, and at regular two-week intervals thereafter until day 382 (week 56). Measurements were conducted with a gas chromatograph (7890A, Agilent Technologies, USA). If CO2 concentrations exceeded 10,000 ppm, the vial's headspace was immediately flushed with synthetic air for three minutes and re-measured afterwards. Raw data were processed following Baysinger and Dolle (2025).

title: Porewater chemistry from sediment core CDISK4-2 from the North Pacific CDisK-IV expedition

description: Samples were collected at six oceanographic stations during cruise CDisK-IV on board RV Kilo Moana from Hawaii to Alaska in August 2017 using an 8-barrel multi-corer. Sediment porewaters were extracted in a cold room, using Rhizon samplers inserted into pre-drilled holes in the core liner, from two cores with undisturbed sediment-water interfaces, from each multi-corer cast. Pre-treatment of the Rhizon samplers and the sampling protocol was different for each of the two cores. Rhizons inserted to core number 1 from each cast were new from the box, and the samples were used for nutrient and major element analyses. A 20 ml syringe was filled from each Rhizon, inserted dry, and the extracted water was filtered again via a 0.45 µm filter. Rhizons inserted to core number 2 were acid-cleaned with 0.001 N HNO3 for at least 24 hours, rinsed with de-ionised water (Milli-Q, Millipore) and kept in de-ionised water until use. The first 1 mL extracted was discarded, and the next 2 mL were stored in acid cleaned polypropylene (PP) vials. These samples, destined for analyses of trace and major elements, were acidified with HNO3 to final acid concentration of 0.035 M.
