Glacial lake hazards

As climate warms, glaciers are receding and exposing overdeepenings that can fill with water to create hazardous lakes. I am working on several projects looking at glacier lake evolution in time and space. I am working on projects in Yukon, BC, and the Himalaya. My colleagues and I are using Google Earth Engine to harness Big Data in order to understand glacial lake evolution across the entire Himalayan region, for example.

A silty glacier-dammed lake of the Brady Glacier, Glacier Bay National Park, Alaska. These glacial lakes can become hazardous if they burst their icy banks and cause floods downstream. The Brady Glacier is the largest glacier in the Park, measuring 40 miles (25 km) long.
