Raw physical oceanography, bio-optical and biogeochemical data from mooring Y4-1 on the Yermak Plateau, Arctic Ocean, July 2022 – June 2023

Time-series data of physical & biological oceanography, nutrient biogeochemistry, molecular biology and carbon/particle export were obtained from mooring Y4-1 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 three Seabird SBE37 MicroCATs (nominal depths: 18m, 37m, 246m, sampling interval 1h), one upward-looking Teledyne RDI 300 kHz Workhorse ADCP (nominal depth: 45m; sampling interval 1h), one Wetlabs ECO PAR sensor (nominal depth: 18m; sampling interval 1h), one Wetlabs ECO Triplet fluorometer (nominal depth: 18m; sampling interval 2h), two Satlantic SUNA nitrate sensors (nominal depths: 18m, 246m; sampling interval 4h), two Sunburst SAMI-pCO2 sensors (nominal depths: 18m, 246m; sampling interval 1h), and two Sunburst SAMI-pH sensor (nominal depths: 18m, 246m; sampling interval 3h). The mooring also included two McLane RAS water samplers (nominal depths: 18m, 246m; raw data not available), and two sediment traps (nominal depths: 191m, 582m; raw data not available). Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable.
