Columbia Glacier Retreating - Geophysical Institute Columbia Glacier, located about 40 kilometers (25 miles) west of Valdez near the epicenter of the great 1964 earthquake, is rapidly losing its battle for survival It is the last of Alaska's 52 tidewater glaciers to begin its epic retreat from the sea Granted, Alaska still has plenty of glaciers left, but the tidewater glaciers--those that empty directly into the sea--are on a drastic decline
The Columbia Glacier | Geophysical Institute The Columbia Glacier is one of Alaska's better known tidewater glaciers, both from the standpoint of tourist attraction and the model it provides for scientific investigation In 1973 it became the object of close scientific scrutiny In Alaska, some 50 to 60 glaciers calve into the sea, but exhibit such diversified behavior that they have baffled glaciologists for decades For instance, some
The majesty and mystery of Alaska yellow cedar | Geophysical Institute These trees, which can live longer than 1,000 years, grow on the rainy coast from the Oregon California border through British Columbia and as far north as Prince William Sound The giants have in many areas died in large numbers, puzzling scientists who later came up with a non-intuitive theory of what killed them
The Shuttle Red Aurora | Geophysical Institute By glowing red on Sunday night, April 12, 1981, the heavens over the United States displayed their pleasure with the successful flight of the shuttle Columbia Perhaps because Columbia was up that night, more Americans than usual looked up at the sky and saw the red aurora that covered much of the nation, even as far south as Texas
Alaska Glaciers Show Dramatic Melting - Geophysical Institute Columbia Glacier in Prince William Sound and Bering Glacier in the St Elias Mountains are two glaciers losing ice at an alarming rate: during the past decade, Columbia has shrunk by an average of about 21 feet per year along the length of the glacier; Bering has lost more than 9 feet per year
Alaska glaciers help drive rise in sea level Predictions for an increased rate of smaller glaciers turning into ocean are conservative, Radic and Hock wrote, because they do not account for the water in icebergs from glaciers that calve into the sea—like Columbia, Hubbard, and hundreds of others in Alaska
The Unknown Legacy of Alaskas Atomic Tests | Geophysical Institute The big daddy came in 1971 Project Cannikin was a 5-megaton explosion that inspired the formation of the group Greenpeace, a group of environmentalists from British Columbia who joined together to oppose the test But Greenpeace and many others-including Alaska senator Mike Gravel and Congressman Nick Begich-were not able to prevent Cannikin
