Past glaciation and sea levels on Bjørnøya, Svalbard

Bjørnøya has a very thin cover of unconsolidated Quaternary sediments. Glacial erratics of local origin are spread throughout the lowland areas, and glacial striae indicate glacial movement which was centred middle of the island. No traces of the Barents Sea ice sheet have been observed on Bjørnøya,...

Description
Summary:Bjørnøya has a very thin cover of unconsolidated Quaternary sediments. Glacial erratics of local origin are spread throughout the lowland areas, and glacial striae indicate glacial movement which was centred middle of the island. No traces of the Barents Sea ice sheet have been observed on Bjørnøya, nor has there been any postglacial emergence of the island. Lake cores date the deglaciation of the lowlands to ca 10,000 BP, and peat deposits on high mountains show that these were deglaciated before 8700 bp.
