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 ...
Seismic record analysis can reveal a glacier’s past | Geophysical Institute
The team analyzed 20 years of Columbia Glacier’s seismic activity to learn what these signals can reveal about changes in the glacier and the conditions that drive them. The glacier has been retreating since the early 1980s after approximately 200 years of stability. The findings were published March 22 in Geophysical Research Letters.
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 Alaska-Canada Boundary | Geophysical Institute
The Alaska-Canada boundary was originally established in February 1825 by Russia (then owner of Alaska) and Great Britain (then owner of Canada).
Alaska climate report: February marked by cold and dynamic weather ...
At the same time, a ridge of high pressure built northward over British Columbia and the Alaska Panhandle, setting up a pattern that steered warmer air from the south into much of mainland Alaska. As a result, temperatures climbed above average across much of mainland Alaska early in the month, although the Arctic Coast remained cold.
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.
The Shuttle Red Aurora | Geophysical Institute
Records taken at Fairbanks indicate that this unusual aurora actually began the night before the launching of the shuttle Columbia. An unusually large magnetic storm, the type of event that causes extensive red auroras, showed its signature at Fairbanks at about 3:00 am local time, Saturday morning, April 11.
Ranking Rivers | Geophysical Institute
For comparison, that's right ahead of the Columbia in area drained and right after it in discharge. (The Columbia River also needs Canada to gain its rank; its source is in British Columbia.) Two Yukon tributaries also make the list. The Porcupine ranks 20th in drainage area, and the Tanana is number 16 for average discharge.
Alaska's Size in Perspective | Geophysical Institute
Alaska is more than twice the size of the largest of the lower 48 states, and the amount of Alaska underlain by permafrost is equal to the size of three Californias. Ten states are smaller than the area covered by glaciers in Alaska. If glaciers of the adjacent Yukon Territory and British Columbia that connect to Alaska's ice fields (often referred to as the Alaska-Yukon glaciers) are added ...
