Along with University of Wyoming colleagues Bryan Shuman, Brandon McElroy, David Williams, and Andrew Parsekian, Dr. Legleiter received a grant from the Wyoming Center for Excellence in Hydrogeophsics (WyCEHG) to conduct research in the nearby Snowy Range. The project, titled Tracking Water Balance, Snowmelt, and Surface-Groundwater Interactions in Sub-Alpine Lakes, will involve acquiring WorldView-2 satellite images and using these data to map lake bathymetry and substrate composition. A smaller, related grant from the Roy G. Shlemon Center for Quaternary Studies will support this project as well. These awards will allow us to add a new graduate student to our research group, focused on lakes in the Snowy Range. Here's a map showing four of the lakes to be targeted, with field measurements of depth from a pilot study on Brooklyn Lake.
Research on meltwater dynamics of Greenland Ice Sheet published in Proceedings of the National Academy of Sciences
Our research group contributed to a study on the meltwater dynamics of the Greenland Ice Sheet. Dr. Legleiter and Ph.D. student are co-authors on the paper by Smith et al. published in the January 27, 2015 issue of the prestigious journal PNAS. In fact, our work was featured on the cover, with the photo shown below.
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.
In preparation for making instructional videos we had to find software that will allow us to record the desktop with sound. The free video player VLC has some nice features which accomplish this task. Below is a quick video walking through the steps.
