Raw physical oceanography and ocean current velocity data from mooring Y5-1 on the Yermak Plateau, Arctic Ocean, July 2022 – June 2023

Time-series data of physical oceanography and ocean current velocities were obtained from mooring Y5-1 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 recovered during PS137 (ALOIS). The attached archive contains raw data files of five Seabird SBE37 MicroCATs (nominal depths: 17m, 37m, 68m, 98m, 243m; sampling interval 10min/1h), nine Seabird SBE56 temperature loggers (nominal depths: 22m, 27m, 47m, 58m, 78m, 148m, 193m, 405m, 471m; sampling interval 30s), one upward-looking Teledyne RDI 300 kHz Workhorse ADCP (nominal depth: 47m; sampling interval 1h), one upward-looking Teledyne RDI 75 kHz Longranger ADCP (nominal depth: 293m; sampling interval 1h), and one RBRDuo wave16 recorder in 4Hz burst mode (nominal depth: 17m; sampling interval 30min). The mooring also included four sets of fouling plates and larvae samplers in collaboration with the Woods Hole Oceanographic Institution, as well as two Develogic Sono.Vault and SVHTI passive and active acoustic recorders (nominal depths: 301m, 303m; data archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable.
