Abstract: The effect of a basalwater 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. (See SIP 20716).
