Raw physical oceanography and ocean current velocity data from mooring F4-20 in the Fram Strait, June 2021 – July 2022

Time-series data of physical oceanography, ocean current velocities and ocean acoustics were obtained from mooring F4-20 in the Fram Strait from June 2021 to July 2022 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 PS126 and recovered during PS131. The attached archive contains raw data files of seven Seabird SBE37 MicroCATs (nominal depths: 76m, 153m, 253m, 402m, 502m, 727m, 1204m; sampling interval 15m/1h), four Seabird SBE56 temperature loggers (nominal depths: 53m, 103m, 203m, 323m; sampling interval 60s), one RDI Workhorse 300kHz ADCP (nominal depth: 53m; sampling interval 60s), one RDI Longranger ADCP (nominal depth: 382m; sampling interval 1h) and two AADI RCM11 current meter (nominal depths: 726m, 1205m; sampling interval 1h). The mooring also included an ASL Acoustic Zooplankton Fish Profiler (nominal depth: 103m, data archived elsewhere) and a Develogic Sonovault (nominal depth: 805m, data archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable. The SBE37 at 253m had power issues and stopped recording after ~5 months.
