Cape Denison lies at the edge of the vast East Antarctic Ice Sheet with an ice volume equivalent to 53 metres of sea level rise. In spite of a century of work, there is a paucity of data on how the ice sheet has changed in the past, limiting our ability to compare current trends, or constrain ice-sheet and climate models. Further north, the landscape of the subantarctic islands suggest that the islands had been deeply incised by glaciers. But to glaciate these islands would need massively different conditions to today’s warm and wet maritime climate. How and when is largely unknown.
