Description Minimum (Interglacial, top) and maximum (Glacial, bottom) extension of the Antarctic ice sheet during the Quaternary climatic cycles. Shaded blue indicate hight steps of 500 m; in the upper graph, turquoise marginal areas are shelf ice, red areas are exposed continent not covered by ice, lines are flow lines (thin) and ice divides (thick). The glacial ice sheet mostly extends due to sea level lowering (see Huybrechts 2002). More ice is grounded on the marginal shelf and the ice sheet thickens due to increasing back pressure.
