Time-series data of ocean acoustics were obtained from mooring F4-OZA-2 in the Fram Strait from July 2020 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 MARIA S. MERIAN expedition MSM93 and recovered during RV POLARSTERN expedition PS131. The mooring included an ASL Acoustic Zooplankton Fish Profiler (nominal depth: 167m; data archived elsewhere), an MTE Aural M2 underwater recorder (nominal depth: 300m; data archived elsewhere) and a Develogic Sonovault (nominal depth: 836m; data archived elsewhere). The attached .zip file only contains the mooring diagrams and folder structure.

The file F4-OZA-2.zip includes all available sensor raw data from mooring F4-OZA-2. 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 MSM93 onboard RV Maria S. Merian 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.
