Seasonal changes in ice sheet motion due to melt water lubrication

IJ Hewitt - Earth and Planetary Science Letters, 2013 - Elsevier
A numerical model is used to calculate how the motion of an idealized ice-sheet margin is
affected by the subglacial drainage of melt water from its surface. The model describes the …
