  • Time-series data of physical oceanography, ocean current velocity, nutrient biogeochemistry, molecular biology, and carbon/particle export were obtained from mooring CAO2-01 in the Amundsen Basin of the central Arctic Ocean in August 2023 – September 2024. The mooring was deployed during RV POLARSTERN expedition PS138 and recovered during PS144. The attached archive contains raw data files of 5 Seabird SBE37 MicroCATs (nominal depths: 26m, 200m, 267m, 3796, 4291; sampling interval 30min or 1h), one upward-looking RDI Workhorse 300 kHz ADCP (nominal depth: 46m; sampling interval 30min), two AADI RCM11 current meter (nominal depths: 215m, 3796m; sampling interval 1h), one Wetlabs ECO PAR sensor (nominal depth: 26m; sampling interval 1h), one Wetlabs ECO Triplet fluorometer (nominal depth: 26m; sampling interval 2h), two Satlantic SUNA nitrate sensors (nominal depths: 26m, 267m; sampling interval 4h), two Sunburst SAMI-pCO2 sensors (nominal depths: 26m, 267m; sampling interval 1h) and two Sunburst SAMI-pH sensors (nominal depths: 26m, 267m; sampling interval 3h). The Sunburst SAMI-pH sensor SN193 had a power issue and did not collect any data. The mooring also included two McLane RAS water samplers (nominal depths: 26m, 267m), an ASL AZFP Acoustic Zooplankton Fish Profiler (nominal depth: 155m), a bio-optical trap (nominal depth: 870m), and two sediment traps (nominal depths: 214m, 3795m). Auxiliary information, such as sensor calibration sheets, mooring diagrams, and schedule files, is also provided, if applicable.
