Supraglacial Meltwater on the Greenland Ice Sheet
Remember to join us for the Miller Lecture with Laurence C. Smith on Friday, April 9 at 11:30 a.m. EDT
Larry is available for individual meetings today and Friday. Use this link to schedule.
About the talk
Meltwater runoff is now the leading process by which the Greenland Ice Sheet is transferring mass to the global ocean. Southwestern Greenland, in particular, experiences extensive melting each summer, creating a transient drainage pattern of supraglacial streams, rivers, lakes, and moulins on the ice sheet surface. This little-studied hydrological system, which is largely unrepresented in current climate/surface mass balance models, interacts with surface mass balance and ice motion in significant ways. This talk presents some recent observational discoveries about Greenland supraglacial hydrology, and their broader implications for modeling ice sheet meltwater runoff and short-term ice dynamics.
