Time-series data of physical oceanography and carbon/particle export were obtained from mooring F4-W-4 in the Fram Strait from, July 2022 – June 2023 as part of the Helmholtz infrastructure program Frontiers in Arctic Marine Monitoring (FRAM) legacy and the long-term monitoring program at AWI HAUSGARTEN. The mooring was deployed during RV POLARSTERN expedition PS131, and recovered during PS136. For this mooring, only the metadata is available here. The profiling winch (nominal depth: 132m) did not record any valid data due to technical issues. The mooring also included one BioOptical Platform (nominal depth: 427m; data archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams and schedule files are also provided, if applicable.

The file F4-W-4.zip includes all available sensor raw data from mooring F4-W-4. 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 PS131 and PS136 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.
