摘要研究了基底水层对冰盖平衡尺度的影响。厚厚的水层可以减少冰盖的平衡厚度，例如南极洲（没有明显的消融区）。类似的平衡尺寸的巨大变化发生在冰河时代的冰盖（具有广泛的消融区域）。还计算了可能被冰碛物覆盖的冰河时代冰盖消融区的范围。
Abstract 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 ablation areas). The extent of the ablation area of an ice-age ice sheet which may be covered with morainal debris is also calculated.
