Raw physical oceanography and profiling winch data from mooring Y2-1 on the Yermak Plateau, Arctic Ocean, July 2022 – June 2023

Time-series data of physical oceanography and ocean current velocities were obtained from mooring Y2-1 on the Yermak Plateau from July 2022 to June 2023 as part of the ATlantic WAter pathways to the ICE (ATWAICE) project. The mooring was deployed during RV POLARSTERN expedition PS131 (ATWAICE) and partially recovered during PS137 (ALOIS). After releasing and recovering the upper mooring segment containing the profiling winch system, sea ice conditions became unfavorable to recover the rest of the mooring. The lower part was then recovered during RV POLARSTERN PS143-2 in 2024. The attached archive contains raw data files of one Seabird SBE37 MicroCAT (nominal depth: 128m; sampling interval 1h), and one AWI profiling winch equipped with a SeaBird CTD, a chl-a fluorometer, a dissolved oxygen sensor, and a CO2 sensor (nominal depth: 127m; sampling interval 4 days). The mooring also included a Develogic Sono.Vault passive acoustic recorder (nominal depth: 308m; data archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable.
