Abstract:
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.

Comment:
The file F4-20.zip includes all available sensor raw data from mooring F4-20. The structure of the unzipped folders is mooring->sensor/sampler type->serial number->instrument files. All instruments were synched to UTC before deployment, and the offset after the recovery is supplied in the respective instrument folder, if available. The archive also contains the sensor calibration sheets/files and relevant sampler schedule files, if available. Finally, mooring schematics are also attached as pdfs in the root folder.
The authors are grateful to the captains, crews and technical/scientific staff of the expeditions PS126 and PS131 onboard RV Polarstern. Many individuals have contributed to the conception of the research, the preparation of the instruments, the deployment and recoveries, as well as to the retrieval of the data, which we greatly appreciate. We acknowledge funding from the Helmholtz infrastructure program "Frontiers in Arctic Marine Monitoring", and the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung.
