Record #130237:

Did subglacial sediment deformation contribute to the rapid deglaciation of the Laurentide ice sheet? / Peter U. Clark, Richard B. Alley.

Title: Did subglacial sediment deformation contribute to the rapid deglaciation of the Laurentide ice sheet? / Peter U. Clark, Richard B. Alley.
Author(s): Clark, Peter U.
Alley, Richard B.
Date: 1994.
In: Eos : transactions, American Geophysical Union. (1994.), Vol. 75(44, supplement) (1994)
Abstract: Abstract. Suggests additional mechanism to solar radiation to explain rapid deglaciation of northern-hemisphere ice sheets every 100 ka. Geological evidence indicates that unstable (surging) behaviour of Laurentide ice sheet over areas of deforming sediment contributed to last deglaciation. Effect of surging over soft beds was to draw-down (thin) ice mass upglacier, and to redistribute this mass downglacier as thin ice carapace now susceptible to rapid melting (high surface area/volume ratio)
