Raw physical oceanography, bio-optical and biogeochemical data from mooring F4-S-5 in the Fram Strait, June 2021 – July 2022

Time-series data of physical & biological oceanography, nutrient biogeochemistry, molecular biology and carbon/particle export were obtained from mooring F4-S-5 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 four Seabird SBE37 MicroCATs (nominal depths: 17m, 22m, 46m, 241m; sampling interval 1h), one SBE56 temperature logger (nominal depth: 36m, sampling interval 60s), one Wetlabs ECO PAR sensor (nominal depth: 22m; sampling interval 1h), one Wetlabs ECO Triplet fluorometer (nominal depth: 22m; sampling interval 2h), two Satlantics SUNA nitrate sensors (nominal depths: 22m, 241m; sampling interval 4h), two Sunburst SAMI-pCO2 sensors (nominal depths: 22m, 241m; sampling interval 1h) and two Sunburst SAMI-pH sensors (nominal depths: 22m, 241m; sampling interval 3h). The mooring also included two McLane RAS water samplers (nominal depths: 22m, 241m; data archived elsewhere), two sediment traps (nominal depths: 194m, 603m; data archived elsewhere), and four PE samplers (nominal depths: 64m, 248m, 503m, 1112m; data archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable. The pH sensor at 22 m and both SUNAs had issues and did not record any data.
