Late-and postglacial environments in the northern Barents Sea west of Franz Josef Land
A lithological and micropaleontological study of three sediment cores from the western Franz Josef Land area, two of them AMS l4C dated, provides new data on the environmental evolution of the northern Barents Sea during and after the last deglaciation. Glacimarine conditions commenced in the deep F...
