Raw physical oceanography, ocean current velocity and bio-optical data from mooring HG-IV-SWIPS-2019 (HG-IV-W-4) in the Fram Strait, August 2019 - June 2021

Time-series data of physical oceanography, ocean current velocities and bio-optical seawater properties were obtained from mooring HG-IV-SWIPS-2019 (alternative name: HG-IV-W-4) in the Fram Strait in August 2019 - June 2021 as part of the Helmholtz infrastructure program Frontiers in Arctic Marine Monitoring (FRAM) and the long-term monitoring program at AWI HAUSGARTEN. The mooring was deployed during RV POLARSTERN expedition PS121, and recovered during PS126. The attached archive contains raw data files of an integrated profiling SBE52plus system (nominal depth: 125m) and a single AADI Seaguard current meter (nominal depth: 154m; sampling interval: 1h). Due to technical issues with the SWIPS winch, the associated sensors only delivered useful profiling data during the first 2 months, albeit at a higher frequency than originally planned. Auxiliary information such as sensor calibration sheets, mooring diagrams and schedule files are also provided, if applicable.
