NASA Explorers: Flying Alaskan Glaciers

Flying low over some of the most dramatic landscapes on the planet, a cadre of scientists and pilots have been measuring changes in Alaskan glaciers as part of NASA’s Operation IceBridge for almost a decade. The team has seen significant change in ice extent and thickness over that time. Data from the mission was used in a 2015 study that put numbers on the loss of Alaskan glaciers: 75 billion tons of ice every year from 1994 to 2013. Last summer, Chris Larsen and Martin Truffer, both of the University of Alaska Fairbanks, flew with University of Arizona s Jack Holt and University of Texas student Michael Christoffersen.
