Glaciers tell stories of the Earth's history; they shape the Earth's surface as they move and form valleys and mountains. Glacial ice documents weather and life from many years past. Tidewater glaciers are those that terminate in the sea. The ice that calves off these glaciers provide important habitat to ice-dependent species, such as seals.

Monitoring Glacial Dynamics
Sensitive to seasonal variation in temperature and precipitation, glaciers are excellent indicators of regional and global climate.
Monitoring Central Alaska Glaciers
Glaciers are inextricably tied to climate and the hydrological cycle, providing base flow to major rivers in Central Alaska.
