Glaciers

As climate continues to warm, glaciers continue to lose volume at an increasingly rapid rate. Fodar is an excellent tool for the measurement of glacier change on annual, seasonal, and even daily time-scales and its orthos can be used for feature tracking to determine velocity fields.

Here is McCall Glacier in the eastern Brooks Range of Alaska in 2013. Mouse-over to see the changes that have occurred over 5 years, compared to a 2008 lidar DEM. Here light blue means no change and red means surface lowering.
