Peculiarities of the Structure and Properties of Ice Ridges in the Eastern Barents Sea Based on the 2003 Expedition Data

摘要

Based on the field research carried out in May 2003 in the easterm part of the Barents Sea, we examined the ensemble of characteristics of 2-year-old ice hummocks, as well as the main features distinguishing them from the annual hummocks of the Barents Sea and other areas of the Arctic regions. Second-year ice floes, on which the ice testing work was carried out, have been found in the immediate proximity of the Shtokman gas condensate deposit. Their occurrence in this area is considered an abnormal phenomenon, caused by the Barents Sea's receiving residual and 2-year-old ice from the northeastern Kara Sea in the winter of 2002-03.
