Results of regional scale sea ice and snow thickness surveys during Nansen Legacy/Synoptic Arctic Survey Joint Cruise 2 (JC2-2) in August – September 2021 using helicopter-borne electromagnetic induction sounding instrument (EM-bird)
The Nansen Legacy/Synoptic Arctic Survey Joint Cruise 2 (JC2-2) was part of the seasonal investigation of the northern Barents Sea and adjacent Arctic Basin. The multidisciplinary cruise was conducted in Aug 24 – Sep 25 of 2021 onboard R/V Kronprins Haakon, and focused on studying the physical, chemical and biological conditions in ocean, atmosphere and sea ice. While in sea ice, we conducted ten regional scale sea ice helicopter-borne surveys of ice conditions using a helicopter-borne electromagnetic instrument (HEM) EM-bird. This dataset presents processed EM-bird data on total snow and sea-ice thickness along the flight tracks.
