Time-series data of physical oceanography, nutrient biogeochemistry, molecular biology, and carbon/particle export were obtained from mooring F4-S-3 in the Fram Strait in July 2018 - August 2019 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 PS114, and recovered during PS121. The attached archive contains raw data files of two Seabird SBE37 microcats (nominal depths: 23m, 50m; sampling interval 1h), one Wetlabs ECO PAR sensor (nominal depth: 23m; sampling interval 1h), one Wetlabs ECO Triplet fluorometer (nominal depth: 23m; sampling interval 2h), one Satlantic SUNA nitrate sensor (nominal depth: 23m; sampling interval 4h), one Sunburst SAMI-pCO2 sensor (nominal depth: 23m; sampling interval 1h) and one Sunburst SAMI-pH sensor (nominal depth: 23m; sampling interval 3h). The mooring also included a McLane RAS water sampler (nominal depth: 23m), a McLane PPS phytoplankton sampler (nominal depth: 25m) and two sediment traps (nominal depths: 204m, 613m). Auxiliary information such as sensor calibration sheets, mooring diagrams and schedule files are also provided, if applicable.

The file F4-S-3.zip includes all available sensor raw data from mooring F4-S-3. 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 PS114 and PS121 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 acknowledge. We acknowledge funding from the Helmholtz infrastructure program "Frontiers in Arctic Marine Monitoring", and the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung.
