Abstract:
Raw physical oceanography data was acquired by a ship-based Seabird SBE911+ CTD-Rosette system (Sensor URN: vessel:polarstern:ctd_sbe9plus_485) onboard RV Polarstern during research cruise PS126 to the Fram Strait as part of the long-term monitoring program at AWI HAUSGARTEN. The installed sensor suite provided duplicates of seawater conductivity (SBE4), temperature (SBE3), pressure (SBE5), depth (calculated), salinity (calculated), dissolved oxygen (SBE43), as well as chl-a fluorescence (Wetlabs FLRTD) and turbidity (Wetlabs C-STAR transmissiometer) within the water column. All sensors performed generally fine, except during one cast where the secondary oxygen sensor had issues below 4000m. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.940754"!

Abstract:
During the RV MARIA S. MERIAN cruise to the Svalbard Archipelago and the Fram Strait during September - October 2020 the Ocean Floor Observation and Bathymetry System (OFOBS) was used to collect still and video images, as well as sidescan data, from various locations surveyed during the research cruise.
The OFOBS system consisted of a towed underwater camera system equipped with both a high-resolution photo-camera (iSiTEC, CANON EOS 5D Mark III) and a high-definition video-camera (iSiTEC, Sony FCB-H11) as well as an integrated sidescan sonar system. The cameras were mounted on a steel frame (140L x 92W x 135H cm), together with two strobe lights (iSiTEC UW-Blitz 250, TTL driven), three laser pointers spaced with a distance of 50 cm used to estimate the size of seafloor structures, four LED lights, and a USBL positioning system (Posidonia) to track the position of the OFOBS during deployments, with additional positioning information provided by the integrated INS and DVL systems.
In automatic mode, a seabed photo, depicting an area of approximately 4 m², with variations depending on the actual height above ground, was taken every ~15 seconds to obtain series of "TIMER" stills distributed at regular distances along each of the survey profiles. Profile lengths varied in length depending on duration of the cast, usually determined by sea state conditions at time of survey. At a ship speed of 0.5 kn, the average distance between seabed images was approximately 5 m. Ship speed was however greatly influenced by ice conditions. Additional "HOTKEY" photos were taken from interesting objects (organisms, seabed features, etc) when they appeared in the live video feed. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.928815"!

Abstract:
Raw physical oceanography data was acquired by a ship-based Seabird SBE911+ CTD-Rosette system onboard Maria S. MERIAN during research cruise MSM93 to the Fram Strait. The installed sensor suite provided duplicates of seawater conductivity (SBE4), temperature (SBE3), pressure (SBE5), depth (calculated), salinity (calculated), dissolved oxygen (SBE43), and Chl-a fluorescence (Wetlabs FLRTD) within the water column. Individual sensor pairs suffered from data quality issues throughout most of the campaign most likely resulting from pump-related problems, but in all affected profiles the duplicate sensor pair was still giving reliable data. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.941682"! ** The authors are grateful to the captain, crew and technical/scientific staff of the expedition MSM93 onboard the RV MARIA S. MERIAN. The work was funded by the Helmholtz infrastructure program “Frontiers in Arctic Marine Monitoring”, and the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung.

Abstract:
The discrete biogeochemical measurements from RV Maria S. Merian MSM77 sampled for organic matter, primary production and phytoplankton abundances. The parameters include POC, phytoplankton abundances and production. The samples were acquired within 0-100 m of the Greenland Sea between 78°N to 80°N and 3°E to 10°E. The data was collected daily on board MSM77 from 16th September 2018-4th October 2018. The water collection occurred using a CTD and laboratory methods varied by parameter. POC was analyzed using a EURO EA CHNS-O Elemental Analyzer, carbohydrates were analyzed using High performance anion exchange chromatography with pulsed amperometric detection, amino acids were analyzed using High Performance Liquid Chromatography (HPLC) ortho-phthaldialdehyde derivatization, rates of primary production (PP) were measured in situ using the 14C method and subsampled as total PP (PP-TOC), particulate PP (PP-POC), and dissolved PP (PP-DOC), cell abundances were measured using orange and red autofluorescence detected by flow cytometry. The purpose of data collection was to understand seasonal cycling of organic mater. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.942624"!
