A tool to evaluate accessibility due to sea-ice cover: a case study of the Weddell Sea, Antarctica
Abstract Sea ice is the major constraint on human activities in the Southern Ocean. Depending on a vessel's ice class, human mobility may be restricted or even prevented altogether by sea-ice conditions. This may imply limited access to research or monitoring stations, preferred fishing grounds...

Abstract Sea ice is the major constraint on human activities in the Southern Ocean.
