Greenland ice sheet hydrology: A review

VW Chu - Progress in Physical Geography, 2014 - journals.sagepub.com
Understanding Greenland ice sheet (GrIS) hydrology is essential for evaluating response of
ice dynamics to a warming climate and future contributions to global sea level rise. Recently …

Seasonal evolution of subglacial drainage and acceleration in a Greenland outlet glacier

I Bartholomew, P Nienow, D Mair, A Hubbard… - Nature …, 2010 - nature.com
