Physical oceanography (CTD/Rosette) during the Akademik Tryoshnikov cruise Transarktika-2019 Leg 1 in 2019, Arctic Ocean

A standard Sea-Bird Electronics SBE911+ CTD system with a temperature and conductivity sensor was used to measure temperature, conductivity, and pressure at 180 stations during the Russian-international expedition Transarktika-2019 Leg 1 in the Barents Sea in March-May 2019 aboard the research vessel Akademik Tryoshnikov. We followed the manufacturer's recommendation to calculate salinity using Seabird processing software. The salinity is reported as Practical Salinity (PSU). Data were averaged at depth ranges of 1 m. Data are provided by the Antarctic and Arctic Research Institute (AARI) and reprocessed at the Helmholtz Centre for Polar and Marine Research, Alfred Wegener Institute. The Transarktika-2019 expedition was made possible by funding from the Russian Federal Service for Hydrometeorology and Environmental Monitoring (Roshydromet). The scientific research was also supported by RFBR grants No. 18-05-60048 and 18-05-60083.
