Divergent flow of the West Antarctic Ice Sheet on the outer contintental shelf of the Amundsen Sea during the late Quaternary
Summary Understanding the past glacial history of regions undergoing potential rapid deglaciation is essential in order to estimate the possible threat of sea level rise. Recently acquired data have given new images of mega-scale glacial lineations on the sea floor of the Amundsen Sea, which provide...
