ScienceDaily (Feb. 23, 2011) — An assessment of coastal change over the past 150 years has found 68 percent of beaches in the New England and Mid-Atlantic region are eroding, according to a U.S. Geological Survey report. Scientists studied more than 650 miles of the New England and Mid-Atlantic coasts and found the average rate of coastal change -- taking into account beaches that are both eroding and prograding -- was negative 1.6 feet per year. Of those beaches eroding, the most extreme case exceeded 60 feet per year.
