Antarctic subglacial topography and ice‐sheet evolution
Abstract Although ice‐sheet flow and form in Antarctica is controlled to a large degree by topography, the continent's landscape evolution and therefore its influence on ice‐sheet development is poorly understood. The oscillation of ice sheets throughout the last 34 million years will have affe...
