Sea ice concentrations in the northern Barents Sea and the area north of Svalbard at Nansen Legacy stations during 2017-2021

The data set contains daily sea ice concentrations for each of the 42 Nansen Legacy stations for the period 2017-2021 derived from AMSR-2 and AMSR-E sea ice concentrations products. The data set is complemented with local sea ice concentration from visual bridge-based observations of the state of sea ice pack conducted following ASSIST Ice Watch protocol during some of the Nansen Legacy cruises to the study area.
