Glaciology and climate

As perhaps the most dynamic of all naturally-deposited porous media, the changing structure of snow reflects changes in weather and the environment. A wealth of satellite imagery exists over the vast expanses of the Antarctic and Greenland ice sheets, yet there is an incomplete understanding of what variations in the images means. From snow and ice cores collected from traverses across the Antarctic Ice Sheet and from several locations on the Greenland Ice Sheet, we are developing the physical basis by which satellite imagery can be used to make high-resolution maps of snow accumulation over vast and remote areas of the ice sheets.
