title: Physical oceanography at CTD station GeoB24304-1 during RV SONNE cruise SO278 in 2020 at the Mediterranean Ridge

description: The main objective of the RV SONNE cruise SO278, which took place between 12.10.2020 to 01.12.2020 was to investigate the interactions between the seabed and ocean water in Greek waters, whereby the plate tectonic constellation of a broad collision zone represents a special tectonic drive. In total, six CTDs were deployed, mainly to sample the methane content in the water column. Oceanographic data as well as water samples were collected at the Olimpi mud volcano field (flare position, Milano MV, Napoli MV), United Nations Rise (Dublin MV), in the fault zone at the northern part of the Mediterranean Ridge and at the site of a subrosional brine pit close to the Nadir brine lakes. Detailed information about the temperature, conductivity and oxygen of the water column have been carried out with a Seabird CTD/Rosette with additional SBE 43 oxygen sensor and a fluorometer. The Rosette contains 24 Niskin bottles with a volume of 10 l.

title: Physico-chemical parameters and accession numbers from the Lilliput hydrothermal field, southern Mid-Atlantic Ridge (9°S)

description: Hydrothermal vent fluids were sampled with a pumped flow-through system with PFA sampling bottles (Kiel Pumping System KIPS) by the ROV QUEST. Fuid chemical parameters were determined immediately after sample recovery. Ph was measured at 20°C in unfiltered sample aliquots. Sulfide concentrations were measured colorimetrcally following the methylene blue method. Fe(II) and Fe(III) was measured colorimetrically with the phenantroline assay. Total Fe was measured by reducing all Fe(III) to Fe(II) with ascorbic acid. Fe(III) was calculated from the diffrence between Fe(II) and total Fe. Light dissolved hydrocharbons were analysed on board applying a purge and trap technique. Dissolved hydrogen was mesured onboard by a GC equipped with a PDD. Stable carbon isotope signatures of methane were analysed using coupled gas chromatography-combustion-isotope ration mass spectrometry. The abundance of bacterial and archaeal taxa was investigated by sequencing of the 16S rRNA gene. The diversity of the cbbL, cbbM and aclb was investigated by sequencing of the genes.
description: Sequence data have been submitted to DDBJ/EMBL/GenBank databases under accession numbers, see data table.

title: Radiosonde measurements in 2020-08 during MOSAiC Leg PS122/4 and PS122/5 (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: Physical oceanography (CTD) during METEOR cruise M148

description: Seabird 911plus systems equipped with dual temperature-conductivity-oxygen sensors were employed. All 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 and Winkler titration , 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 PS117

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 PS117 (Cape Town – 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: U-Series isotopes analytical results (U & Th) on core PS2757-6 (MUC)

description: Core PS2757-6 was retrieved with a multicorer (MUC) on the Lomonosov Ridge next to the Russian continental shelf during the Polarstern expedition ARK-XI/1 in 1995. This expedition had the principal aim to study material fluxes and ecological connections between the Arctic Deep Basins and the adjacent Siberian shelf seas, the northern Laptev Sea and the northeastern Kara Sea. In 2018 and 2019, this core had samples analyzed by MC-ICPMS at the Geotop-UQAM laboratories for uranium-series isotopes with the aim to establish radiochronological age constraints for the coring location.
