Modern Evolution of Seabed Conditios of Northern Baffin Bay and Adjacent Areas
The purpose of research work is to analyze indicators of geological, geographical and climatological processes of evolution of seabed conditions of Northern Baffin Bay and adjacent areas in the Last Glacial Maximum to Holocene. Baffin Bay is the northwestern extension and terminus of the North Atlan...
