Using rock and sediment samples from raised beach ridges and glacier moraines for dating to determine the extent of the ice sheet during the last glacial maximum
Entry ID: K043_1996_1998_NZ_2

Abstract: Raised beaches on the coast of McMurdo Sound have developed since the last glacial maximum approximately 20,000 year ago when the ice sheets were at their greatest extent. The weight of the overlying ice depressed the land which has slowly rebounded after the ice melted, forming a series of beach ridges. The beach ridges and associated rock platforms were dated using three different methods and ... View entire text
