Vessel mounted Acoustic Doppler Current Profiler data collected in the Barents Sea and adjacent Arctic Ocean by the Norwegian research icebreaker R/V Kronprins Haakon, during 7 individual surveys conducted for the Nansen Legacy project.

Post-processed vessel mounted 150kHz Acoustic Doppler Current Profile (VM-ADCP) data, collected during 7 individual surveys in the Barents Sea and Arctic Ocean, conducted as part of the Nansen Legacy project. The VM-ADCP data were processed with the CODAS processing software package (Hummon, 2016), using 5 min temporal bins and 5 m depth bins Key variables are Velocity East, Velocity North and Velocity Up. The dates and locations of each individual cruise are as follows: Joint cruise 1-2/2018707; 2018-08-06 to 2018-08-23; Northwestern Barents Sea, Nansen Basin.
