title: Thorium and Uranium in sediment core PS1533-3

description: This dataset merges information from five sources and adds newly calculated data. Original radionuclide data and sand content are taken from Frank and Eisenhauer 1996. The age scale and stable isotopes were taken from Spielhagen et al. 2004, with AGE [ka BP] being based on calibrated 14C ages and "Age dated [ka]" being a radiocarbon age with 402 years reservoir correction. From these data, 230Thex recalculated (230Th-234U), authigenic uranium (assuming 238U/232Th of 0.6), ingrowth of 230Th from authgenic uranium (using the Spielhagen et al. 2004 ages) and 230Thex noauth (corrected for ingrowth from authigenic uranium but not decay) were calculated.

title: Whale sightings during POLARSTERN cruise PS112 (ANT-XXXIII/3)

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 PS112 (Punta Arenas - Punta Arenas) 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: Date/Time is given in UTC. Certainty of identification: definite if observer clearly identified the species. The number of individuals is binned according to the options given in the data acquisition software: 1, 2, 3, less equal 5, less equal 10, greater than 10, greater than 20. More precise values may exist, due to observer comments.

title: Stable isotopes measured on N. pachyderma and C. neoteretis of sediment core PS93/025

description: Measured stable isotopes of N. pachyderma & C. neoteretis (without vital effect correction).The sampled sediment record PS93/025, consisting of the Giant box core (GKG) PS93/025-1 (80.481°N, 8.487°W, 291.3 m water depth) and the Kastenlot core (KAL) PS93/025-2 (80.482°N, 8.490°W, 290.2 m water depth), was obtained during the expedition PS93.1 (2015) (Stein, 2016) of RV Polarstern on the outermost NE Greenland shelf in the western Fram Strait.The presented data covers the last ca. 10.6 ka.For stable oxygen and carbon isotope analyses, ca. 30 specimens of N. pachyderma and the benthic foraminifer species Cassidulina neoteretis from the 100–250 μm fraction were used. The measurement interval is 1 cm for both species between 264 and 93 cm, whereas it shifts to ca. 2 cm for the benthic species and 5 cm for the planktic species between 93 cm and 0.5 cm, due to low numbers of specimens. All analyses were carried out on a MAT 253 mass spectrometer system and a KIEL IV Carbonate Preparation Device at the GEOMAR Stable Isotope Laboratory with a long-term analytical accuracy of &lt;0.06‰ for δ18O and &lt;0.03‰ for δ13C. Results are expressed in the δ notation referring to the PDB (Pee Dee Belemnite) standard while using NBS 19.Aim of the study was to reconstruct the climatic and paleoceanographic variability offshore Northeast Greenland during the last ca. 10ka with multidecadal resolution.

title: Benthic and planktic foraminiferal records of sediment core PS93/025

description: Benthic and planktic foraminiferal fluxes, planktic foraminiferal fragmentation and proportions of N. pachyderma & T. quinqueloba. The sampled sediment record PS93/025, consisting of the Giant box core (GKG) PS93/025-1 (80.481°N, 8.487°W, 291.3 m water depth) and the Kastenlot core (KAL) PS93/025-2 (80.482°N, 8.490°W, 290.2 m water depth), was obtained during the expedition PS93.1 (2015) (Stein, 2016) of RV Polarstern on the outermost NE Greenland shelf in the western Fram Strait. The presented data covers the last ca. 10.6 ka. In representative splits of the 100-250 µm size fraction, planktic and benthic foraminifers were determined and counted. Benthic and planktic foraminiferal fluxes (individuals/cm2*ka) were calculated to serve as a semiquantitative proxy for bioproductivity. Fragmentation of planktic foraminifers was calculated by counting fragments which were no more determinable to species level. Thereby, the equation from Pfuhl and Shackleton (2004) was used which includes a fragment-divisor of 3. The percentage share of the subpolar planktic foraminifer species Turborotalita quinqueloba and the polar planktic species Neogloboquadrina pachyderma was calculated as a proxy for the advection of warmer water masses (e.g. Volkmann, 2000). Aim of the study was to reconstruct the climatic and paleoceanographic variability offshore Northeast Greenland during the last ca. 10ka with multidecadal resolution.

title: Hyperspectral downward irradiance observed during cruise M148/2 aboard METEOR

description: Automated continuous above-water hyperspectral calibrated radiometric quantities were observed in the international waters of the Atlantic Ocean during the scientific field campaign M148/2 aboard RV METEOR. The cruise began on 02 July 2018 from Walvis Bay, Namibia and was completed on 20 July 2018 in Las Palmas de Gran Canaria, Spain. A radiometer setup, with two TriOS RAMSES-ACC hyperspectral cosine irradiance meters to measure incoming solar irradiance, four TriOS RAMSES-ARC hyperspectral radiance meters to measure total upward sea surface leaving radiance Lsfc at 45° nadir and sky-leaving radiance Lsky at 45° zenith angle, was installed using a custom-made frame at the bow of RV METEOR. The frame was attached to the bow of the ship with the radiance meters having a 90° azimuthal angle separating them. Quality control involved retaining the Lsfc observations with lowest values (Garaba et al., 2012; Garaba et al., 2015). Data logging was automated using TriOS MSDA XE version 8.9.2 software and further processing was done using Mathworks Matlab 2016a and R software. Processed data was interpolated to 1 nm spectral resolution using PCHIP function in Matlab between 320 and 950 nm. Raw data is available on request.

title: Ice rafted debris flux and composition of sediment core PS93/025

description: IRD flux and the corresponding petrographic grain composition. The sampled sediment record PS93/025, consisting of the Giant box core (GKG) PS93/025-1 (80.481°N, 8.487°W, 291.3 m water depth) and the Kastenlot core (KAL) PS93/025-2 (80.482°N, 8.490°W, 290.2 m water depth), was obtained during the expedition PS93.1 (2015) (Stein, 2016) of RV Polarstern on the outermost NE Greenland shelf in the western Fram Strait. The presented data covers the last ca. 10.6 ka. Ice-rafted debris counts were performed on the &gt;150 μm fraction at steps of 5 cm. The results are expressed as flux rates (grains/cm2*ka). Additionally, the corresponding petrographic grain composition was analyzed to determine the source area(s) of these lithic particles by using the following groups: (a) clastic sedimentary rocks (e.g. siltstones); (b) metamorphic rocks (e.g. quartzites), volcanic rocks (e.g. basalt), olivine grains, volcanic glass shards, mica; (c) crystalline rocks, quartz and feldspar; (d) limestones and dolomites. Rounded grains were specified following St John et al. (2015) to identify the influence of sea-ice sediments. In this study, grains with subrounded and rounded shape were counted and grouped as "rounded." Aim of the study was to reconstruct the climatic and paleoceanographic variability offshore Northeast Greenland during the last ca. 10ka with multidecadal resolution.
