Record #105502:

The ice topography over subglacial lakes / E.M. Shoemaker.

Title: The ice topography over subglacial lakes / E.M. Shoemaker.
Author(s): Shoemaker, E. M.
Date: 1990.
In: Cold Regions Science and Technology. (1990.), Vol. 18(3) (1990)
Abstract: Model developed which relates topography to length of bed transition regions bordering lake, where effect of presence of lake causes reduction in basal shear stress. Model is applied to four representative regions of ice sheet. If length of bed transition region is <1 km, slight to moderate depression is created in ice. If larger, flat area is created. Normally, it should be sufficiently large that ice surface is not expected to develop depression unless region is close to ice divide.
