Even more exciting, the researchers have multi-temporal data for 20,000 of the glaciers in the database -- meaning they have pictures of these 20,000 glaciers over the course of several years. Although the overall findings of the project were that glaciers are losing mass in general, the huge dataset also gives glaciologists an unprecedented ability to look at the smaller, more complex variations on a regional scale. Using the satellite data, they can try to see patterns in glacier behavior. "One thing that we are better able to address is the question of why there are variations in glacier responses," Kargel says. Glaciers behave differently at different elevations and in different climates. With a global picture, scientists like Kargel can figure out why those changes exist.
