Northern Alaska Coastal Erosion

Coastal erosion has more than doubled in Alaska – up to 45 feet per year – in a 5-year period between 2002 and 2007 along a 40-mile stretch of the Beaufort Sea.

The U.S. Geological Survey-led study reveals that average annual erosion rates along this part of the Beaufort Sea climbed from historical levels of about 20 feet per year between the mid-1950s and late-1970s, to 28 feet per year between the late-1970s and early 2000s, to a rate of 45 feet per year between 2002 and 2007. The study was published in the current issue of Geophysical Research Letters, a publication of the American Geophysical Union.
