Remote sensing of supraglacial streams yields insight on meltwater dynamics of the Greenland Ice Sheet
In July 2012, Dr. Carl Legleiter and PhD student Brandon Overstreet conducted an intensive field investigation on the surface of the Greenland Ice Sheet, along with colleagues from UCLA, JPL, Rutgers, and CUNY. Our group's main contribution was measurements of depth and reflectance in supraglacial lakes and streams, which allowed us to map bathymetry from WorldView-2 satellite images. This capability enabled modeling of the ice sheet's meltwater dynamics and a paper based on this study has just been published in the prestigious journal Proceedings of the National Academy of Sciences. Here's a link to a NASA press release on the study and another link to the paper itself. Below is a photo of Legleiter and Overstreet in Greenland.
