Helicopter-borne sea-ice thickness measurements from the 2014 IRO2 /ESA SMOSice campaign cruise in the Barents Sea region

Helicopter-borne electromagnetic induction sounding (HEM) sea ice thickness measurements made in the Barents Sea region in March 2014. A total of 8 separate flights were conducted during this campaign. The thickness produced by this sensor is ‘total thickness’, that is ice + snow, but is normally referred to as ‘sea-ice thickness’. This work was supported by the European Space Agency SMOSice project (ESA contract 4000110477/14/NL/FF/lf). We would like to thank the crews of Airlift helicopter and RV Lance for their assistance with the collection of this dataset.
