Abstract

Results of high-resolution research of recent bottom sediments from south, central and north Chukchi Sea reveal striking data on environmental changes during the last decades. The composition of surface sediments from the Arctic Sea gives evidence of the decrease of ice cover and an increase of biogenic elements, caused by higher bioproductivity.
