title: Snow height on sea ice and sea ice drift from autonomous measurements from buoy 2018S72, deployed during AKADEMIK TRYOSHNIKOV cruise TRANSDRIFT XXIV / TICE

description: Snow height was measured by the Snow Depth Buoy 2018S72, an autonomous platform, drifting on Arctic sea ice, deployed during AKADEMIK TRYOSHNIKOV cruise TRANSDRIFT XXIV (TICE). The resulting time series describes the evolution of snow depth as a function of place and time between 13 September 2018 and 14 May 2020 in sample intervals of 1 hour. The Snow Depth Buoy consists of four independent sonar measurements representing the area (approx. 10 m**2) around the buoy. The buoy was installed on multi year ice. In addition to snow depth, geographic position (GPS), barometric pressure, air temperature, and an internal ice temperature were measured. Negative values of snow height occur if surface ablation continues into the sea ice. Thus, these measurements describe the position of the sea ice surface relative to the original snow-ice interface. Differences between single sensors indicate small-scale variability of the snow pack around the buoy. The data set has been processed, including the removal of obvious inconsistencies (missing values). Records without any snow depth may still be used for sea ice drift analyses.

title: Radiosonde measurements in 2020-06 during MOSAiC Leg PS122/3 and PS122/4 (level 2 data)

description: This is a Level 2 dataset of radiosondes launched during the MOSAiC expedition. The balloon-borne radiosondes measured temperature, pressure, relative humidity and wind from board R/V Polarstern to about 30 km height, commonly four times daily during the entire expedition period. The objective of Level 2 is to provide the user community with a usable data product before the final processed product is completed. Quality control for appropriate physical ranges has been applied. However, it should be noted that potential inconsistencies in the physical data in particular in the lowermost part of the profiles are not corrected. This regards e.g. GPS altitude close to the surface and wind direction at latitudes &gt;89° N.

title: CARD-FISH cell counts of taxonomic bacterial groups from different microbiomes in Fram Strait used to evalute primer sets

description: Samples in this dataset were collected at the long-term ecological research (LTER) site HAUSGARTEN in Fram Strait, and the central Arctic Ocean. On board, the samples were fixed with formalin in a final concentration of 2% for 10 – 12 hours, then filtered onto 0.2 µm polycarbonate Nucleopore Track-Etched filters, and stored at -20°C for further analysis. Cell abundances of the groups Alteromonas, Bacteroidia, Polaribacter, Gammaproteobacteria and the SAR11 clade were asses using CAtalyzed reporter deposition Fluorescence In Situ Hybridization (CARD-FISH) following the protocol established by (Pernthaler et al., 2002). The filters were evaluated microscopically under an automated microscope (Zeder et al., 2011). Cell enumeration was performed with the software Automated Cell Measuring and Enumeration Tool (ACMETool3, 2018-11-09; Zeder et al., 2011). Cells were counted as objects according to manually defined parameters separately for the DAPI and FISH channels.

title: Physical oceanography (CTD) during SONNE cruise SO234/2

description: Seabird 911plus systems equipped with dual temperature-conductivity-oxygen sensors were employed. The systems had a 24-bottle water sampling rosette with 10 l Niskin bottles. Water sampling, processing, and calibration followed GO-SHIP recommendations (Swift, 2010; McTaggart et al., 2010; Uchida et al., 2010) and included the recommended steps Data Conversion, Sensor Time-Alignment, Creation of Bottle Files, Outlier Removal, Pressure Sensor Filtering, Conductivity Cell Thermal Mass Correction, Ship Roll Correction and Deck Offset Correction by Loop Editing, as well as Derivation of Calculated Properties. After these steps, conductivity and oxygen readings were calibrated against values determined with salinometry (see section 4.1.4) and Winkler titration (see section 4.2.1), respectively. Finally, the downcast data was averaged over 1 dbar wide intervals. An independent upcast calibration was used to obtain calibrated CTDO values coincident with the discrete water samples.

title: Whale sightings during POLARSTERN cruise PS119

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 PS119 (Punta Arenas – Port Stanley) 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.
