title: Grain size data from ODP Site 162-985

description: Records of grain size data measured on the coarse fraction of sediment samples taken during Ocean Drilling Program Site 985 from the Norwegian Sea. For the studies of the coarse fraction the samples were freeze-dried using a FINN-AQUA (lyvotac GT2). Part of the freeze-dried sample was weighed and then washed on a 63-µm sieve and further separated into 63- to 125-, 125- to 500-, 500- to 1000-, and &gt;1000-µm fractions using an ATM-SONIC-Sifter. The 125- to 500-µm fraction was chosen for particle count procedure.

title: Airborne low-altitude snow depth on sea ice during aircraft flight P5_205_PAMARCMIP_2017_1704041501, Version 1

description: Airborne observations of snow depth on sea ice were made in March and April 2017 as part of the Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMIP) under the AWI IceBird campaign series. The data consist of six surveys spanning sea-ice covered areas in the Lincoln Sea, Central Arctic Ocean, as well as the Beaufort and Chukchi Seas. For each flight, the geolocated snow depth data from an airborne frequency-modulated continuous-wave ultrawideband radar using an algorithm based on signal peakiness are provided with a point spacing of approximately 4-5 meters. The trajectory data contain the full and unfiltered data record with quality flags. Longer sections of altitude-flagged data arise from calibrations of an EM sensor. Each snow depth value represents the average depth within the radar footprint that has a theoretical smooth surface cross-/along-track diameter of 2.6/1.0 m.

title: Airborne high-altitude snow depth on sea ice during aircraft flight P6_217_ICEBIRD_2019_1904101401, Version 1

description: Airborne observations of snow depth on sea ice were made in April 2019 during the winter campaign of the AWI IceBird campaign series. The data consist of five surveys, some with overlapping segments at low and high altitude, spanning sea-ice covered areas in the Lincoln Sea, Central Arctic Ocean, as well as the Beaufort Sea. For each flight, the geolocated snow depth data from an airborne frequency-modulated continuous-wave ultrawideband radar using an algorithm based on signal peakiness are provided with a point spacing of approximately 4-5 meters for low-altitude flights and 7-9 meters for high-altitude flights. The trajectory data contain the full and unfiltered data record with quality flags. Longer sections of altitude-flagged data in the low-altitude data arise from calibrations of an EM sensor. Each snow depth value represents the average depth within the radar footprint that has a theoretical smooth surface cross-/along-track diameter of 2.6/1.0 m at low altitude and 7.2/5.1 m at the high altitude.

description: Isotopic composition of the top-meter of the snowpack along a 115km traverse between B31 and D48, near Kohnen station, Droning-Maud Land, East-Antarctica. The upper 100cm snow was sampled with the dual-tube sampling technique (Dallmayr et al., 2020), or by mixed subsections of the top-120cm of 90m long trenches excavated by piston-bully. The isotopic analysis were realized by CRDS (Cavity-Ring-Down Spectroscopy, l2130-i, Picarro Inc.) at the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar-und Meeresforschung, in Bremerhaven and in Potsdam, Germany.

title: XRF data of different calcareous nannofossil at 7.5 keV

description: The data were generated at ESRF beamline ID21 with an incident energy at 7.5 keV. Coccolithus pelagicus, Discorhabdus striatus, Helicosphaera carteri and Watznaueria britannica were analyzed with 0.4 µm x 0.4 µm pixel size and 3 s time analysis per pixel. Calcidiscus leptoporus was analyzed with 0.2 µm x 0.2 µm pixel size and 1.5 s time analysis per pixel. Dicoaster falcatus was analyzed with 0.5 µm x 0.5 µm pixel size and 3 s time analysis per pixel. Data treatment is made using PyMCA. For each calcareous nannofossil, the raw data (.edf in .zip) and the pondered spectrum (.csv) are given. One fit file is given (.cfg). It may be applied to any sample but for further calculation, new fit file specifically adapted to the sample should be used. Those data were acquired through the project ES113 at ESRF. Coccolithus pelagicus is from North Atlantic sediment coretop GIK23066. Discorhabdus striatus is from Murtinheira section at Cabo Mondego, Portugal sample CM9. Watznaueria britannica is from Murtinheira section at Cabo Mondego, Portugal sample CM60. Sample position in the Murtinheira section at Cabo Mondego in Suchéras-Marx et al. (2012). Helicosphaera carteri and Calcidiscus leptoporus are from South Atlantic sediment coretop GeoB3721-4. Discoaster falcatus is from Wilson lake core, NJ, USA.

title: Living coccolith assemblages of surface sediment samples from the Pacific sector of the Southern Ocean

description: This study examined recent coccolith surface sediment assemblages across the Pacific sector of the Southern Ocean (from Punta Arenas, Chile toWellington, New Zealand). Twenty five stations located within 44.4°S to 65.4°S and 80.1°W to 174.5°E were selected in order to assess if and how the surface sediment assemblages reflect the present-day coccolithophore community and surface-water oceanographic conditions. The highest numbers of coccoliths in the surface sediments are reached near the East Pacific Rise and close to the Subtropical Front, at the New Zealand Margin (&gt;6x109 coccoliths/g of sediment). The dominant taxa are Emiliania huxleyi (including types A, B, B/C and C), Calcidiscus leptoporus, Gephyrocapsa spp. (including G. muellerae, G. oceanica and G. ericsonii), Umbellosphaera tenuis and Coccolithus braarudii. Despite the recognition of species morphotypes being hampered by carbonate dissolution at some locations, we observed that numbers generally decrease southward until almost a monospecific and sporadic record of E. huxleyi (types B/C and C) and C. leptoporus south of the Polar Front occurs. The recent coccolithophore distribution was compared to already published living coccolithophore distributions (i.e., water column samples collected at the same specific locations) showing a fairly similar pattern. Combining the numbers of cells/l and coccoliths/g of sediment, different coccolithophore assemblages were established coincidentwith areas bounded by the major surface oceanographic fronts, i.e. the Subantarctic Zone and the Polar Front Zone.

title: Airborne sea ice parameters during aircraft flight P6_217_ICEBIRD_2019_1904020901, Version 1

description: Airborne multi-instrument measurements of sea ice were made in April 2019 during the winter campaign of the AWI IceBird campaign series. The data consist of five surveys spanning sea-ice covered areas in the Lincoln Sea, Central Arctic Ocean, as well as the Beaufort Sea. For each flight, the geolocated total (ice+snow) thickness data from an airborne electromagnetic (EM) induction sensor are provided with a point spacing of approximately 5-6 meters. Larger gaps in the trajectories arise from high-altitude calibrations of the EM sensor. The data are combined with collocated and simultaneous snow depth measurements from an airborne frequency-modulated continuous-wave ultrawideband radar, snow freeboard measurements from an airborne near-infrared laser scanner, and surface temperature measurements from an airborne infrared radiation pyrometer. Each value represents the average within the approximately 40 m diameter footprint of the EM sensor, thus representing a smoothed representation. These values are then used to derive further sea ice parameters such as sea ice bulk density. The trajectory data contain the full and unfiltered data record with quality flags.
