Bottom topography of the Kara sea

Abstract

The development of the Kara Sea bottom topography is connected with eustatic Neogene-Quaternary fluctuations of the sea level. With regard to morphological and genetic .aspects the bottom topography is represented by surfaces of dissection and by surf aces of complete and incomplete planation formed both under subaerial, subaqual conditions and under «mixed» conditions of the present-day coastal zone. Besides genetically homogeneous surfaces there exist submarine valleys of different genesis and forms of coastal morphosculpture. Submarine valleys were changed to a different degree by wave abrasion-accumulative processes. Their mouths, reflecting the epochs of maximum regressions, are strictly related to certain bathimetric levels.
