Implementing a cartographic repository of the postglacial Antarctic paleo-shorelines
An improved understanding of the chronology of Antarctic ice sheet deglaciation since the Last Glacial Maximum-LGM represents a fundamental tool to better define the origin of past and future meltwater influx in the global oceans (Whitehouse et al., 2012). Relict shorelines and other evidence of pas...
