Rate of late Quaternary ice‐cap thinning on King George Island, South Shetland Islands, West Antarctica defined by cosmogenic 36 Cl surface exposure dating
Glacial landforms on the Barton and Weaver peninsulas of King George Island in the South Shetland Islands, West Antarctica were mapped and dated using terrestrial cosmogenic 36 Cl methods to provide the first quantitative terrestrial record for late Quaternary deglaciation in the South Shetland Isla...
