Time-series data of physical oceanography and ocean current velocities were obtained from mooring IdF3-2 close to Île-de-France in the Greenland Sea from August 2022 to October 2025. The mooring was deployed during RV POLARSTERN expedition PS131 (ATWAICE) and recovered during PS150 (EGCSources). The attached archive contains raw data files of 3 Seabird SBE37 MicroCATs (nominal depths: 150m, 280m, 350m; sampling interval 10min), 4 SeaBird SBE56 temperature loggers (nominal depths: 180m, 210m, 240m, 320m; sampling interval 60s), and one upward-looking RDI 150 kHz Quartermaster ADCP (nominal depth: 348m; sampling interval 1h). Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable. The ADCP ran out of power on 02 February 2025. The 4 SBE56 had a time offset of -24h for unknown reasons. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.993837"! ** The file IdF3-2.zip contains all available sensor raw data from the mooring IdF3-2. The structure of the unzipped folders is mooring->sensor/sampler type->serial number->instrument files. All instruments were synchronized to UTC before deployment, and the time 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 PS150 aboard 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 financial support from the Helmholtz infrastructure program Frontiers in Arctic Marine Monitoring (FRAM), and the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar und Meeresforschung.
