Late Weichselian and Holocene Relative Sea-level History of Bröggerhalvöya, Spitsbergen
Abstract Radiocarbon-dated whalebones from raised beaches record a relative sea-level history for Bröggerhalvöya, western Spitsbergen that suggest a two-step deglaciation on Svalbard at the end of the late Weichselian glaciation. The late Weichselian marine limit was reached at about 13,000 yr B.P....
