The effect of a basal water layer on the equilibrium dimensions of an ice sheet is examined. A thick water layer can decrease the equilibrium thickness of an ice sheet such as covers Antarctica which contains no significant ablational areas by a factor of the order of 2. Similar large changes in the equilibrium dimensions occur for ice-age ice sheets which have extensive ablational areas. The extent of the ablation area of an ice-age ice sheet which may be covered with morainal debris also is calculated. Author
