Alterations of the heaviest ice conditions along Sabetta-Bering Strait route
Abstract AARI has unique archive of ice charts, which were made by recognition of satellite images, their composition and vectorization. The paper is considered methodology and preliminary results of computer processing of vector ice charts from the archive. The archive covers the period since 1997....
