Eastern Arctic Ice Extent Declined By 20% From 1920 To 1939

It has been noted that year by year, for the past two decades, the fringe of the Polar icepack has been creeping northward in the Barents Sea. As compared with the year 1900, the total ice surface of this body of water has decreased by twenty per cent. Various expeditions have discovered that warmth-loving species of fish have migrated in great shoals to waters farther north than they had ever been seen before. Recession of the Barents Sea ice fields have been verified in recent years by numerous vessels of the Soviet mercantile marine plying between Murmansk and Spitzbergen.
