Raw data of physical oceanography and current velocity from mooring AK2-1 in the Arctic Ocean in 2015-2018

Time series data of physical oceanography (seawater conductivity, temperature, pressure, salinity) and ocean current velocities were obtained from mooring AK2 in the eastern Arctic Ocean north of Severnaya Zemlya (81.903 °N, 94.482 °W, water depth 898 m) in 2015 - 2018. The mooring was deployed during Akademik Tryoshnikov expedition AT2015 as part of the NSF-funded NABOS (Nansen and Amundsen Basins Observational System) - program and recovered during AT2018, which was jointly organized between NABOS and the German BMBF-funded CATS (Changing Arctic Transpolar System)-project. The attached archive contains raw data files of Seabird SBE37 microcats, Seabird SBE26 bottom pressure recorders, RDI Acoustic Doppler Current profiler and Aanderaa point current meters. Auxiliary information such as sensor calibration sheets, mooring diagrams and schedule files are also provided, if applicable.
