Exploring permafrost coastal erosion in the Arctic

The remote town of Barrow, Alaska, home to more than 4,000 people, touts picturesque views of the Arctic Ocean as well as an unparalleled connection to the Alaskan wild, but underneath its stunning beauty lies a major global crisis — permafrost coastal erosion — causing Barrow to gradually slip into the sea.

USGS models: Florence likely to cause short- and long-term beach erosion

Hurricane Florence, a dangerous Category 4 hurricane, is very likely to cause beach erosion along about three-quarters of the North Carolina coast as it makes landfall, and to overwash about 15 percent of that state’s dunes, with less extensive erosion in nearby states, say coastal change experts at the U.S. Geological Survey
