Latest Supraglacial lake Stories
Prevailing models from the melting of the Greenland ice sheet have made the calculation that the ice sheet sits atop hard bedrock. A new study from a team of British and American scientists has thrown out that assumption, however.
Lakes often form on top of a glacier and drain onto the bedrock below, lubricating a glacier's movements as a result. A new study from an international group of researchers has found the way these lakes drain can affect the velocity, extent and direction of a glacier's progress.
Scientists reported on Friday that Greenland's icesheet shed a record amount of melted snow and ice in 2010.
Scientists have uncovered a plumbing system for the Greenland ice sheet, where meltwater can penetrate thick, cold ice and accelerate some of the large-scale summer movements of the ice sheet.
