Time series data of physical oceanography (seawater conductivity, temperature, pressure, salinity) and ocean current velocities were obtained from mooring AK3 in the eastern Arctic Ocean north of Severnaya Zemlya (81.962 °N, 94.543 °E, water depth 1453 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 processed current velocities and hydrographic data recorded with Seabird SBE37 microcats, RDI Acoustic Doppler Current profilers and Aanderaa point current meters. Details on data processing can be found in the file description and in Ruiz-Castillo et al. (2022). Instruments types and serial numbers can be found in the attached document.
