Time-series data of ocean current velocities and carbon/particle export were obtained from mooring F4-W-3 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 one AADI RCM11 current meter (nominal depth: 143m; sampling interval 1h) and a profiling underwater winch (nominal depth: 114m). The mooring also included one BioOptical Platform (nominal depth: 420m; data archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams and schedule files are also provided, if applicable. The winch had issues and did not record valid data, but the available files are included here for completeness.

The file F4-W-3.zip includes all available sensor raw data from mooring F4-W-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 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.
