Modern and Relict Evidence of Iceberg Scouring at the Bottom of the Barents and Kara Seas

The article systematizes and summarizes published data on the parameters and distribution areas of modern and relict iceberg scours (or plough marks), as well as on the maximum possible sizes and drift areas of modern icebergs in the Barents and Kara seas. According to open-source bathymetric data, for the first time, analysis of the “throughput” of the waters in front of modern glaciers has been carried out. Based on summarized and established facts, areas of the most likely distribution of modern iceberg effects on the bottom are determined by expert assessment. This study is relevant both from a fundamental viewpoint and for determining the current depth limits of iceberg scouring at the bottom of the Barents and Kara seas, which is important for ensuring the geoecological safety of all kinds of activity on the sea shelf.
