Winter storms accelerate the demise of sea ice in the Atlantic sector of the Arctic Ocean
A large retreat of sea-ice in the stormy Atlantic Sector of the Arctic Ocean has become evident through a series of record minima for the winter maximum sea-ice extent since 2015. Results from the Norwegian young sea ICE (N-ICE2015) expedition, a five-month-long (Jan-Jun) drifting ice station in fir...
