Subsea uplifts origin of the Rugozerskaya bay and the Great Salma channel (Kandalaksha Bay)

Abstract

The origin of the subsea uplifts of the Rugozerskaya bay and the Great Salma strait is discussed in this article. It was found that the present-day bottom surface of the investigation area imitates the post-glacial terrain. This was determined by accumulative glacial formations that were emulated with post-glacial sedimentation processes. All modern bottom uplifts are similar to the ancient post-glacial terrain. Most presentday bottom surface depressions are similar to post-glacial surface inequalities, but the configuration of modern closed kettles could be changed via glacial–marine sedimentation and other processes.
