Scott Luthcke of NASA's Goddard Space Flight Center, Greenbelt, Md, and coauthors, used GRACE data and found that the annual ice mass lost from glaciers in the Gulf of Alaska has been 84 gigatons annually, about five times the average annual flow of the Colorado River through the Grand Canyon, and equal to the entire amount of water in the Chesapeake Bay. See http://www.nasa.gov/topics/earth/features/glacier_tech.html for details.
