Holocene glacial and climatic variations on Spitsbergen, Svalbard
Holocene glacial and climatic variations have been inferred from investigations of sediment cores from the proglacial lake Linnévatnet, western Spitsbergen. A low content of glacially derived coal, absence of regular laminations and a slow sedimentation rate in the lower part of the lacustrine sedim...
