Fire Island, NY

By Andrew Cooper

Fire Island, NY is a barrier island that runs east to west on the southern coast of Long Island in New York. Like much of the coast in the area, the island has been heavily modified in an effort to slow the natural erosion and landward migration of the barrier island.

These efforts to slow the natural erosion involve massive fabric tubes filled with sand called geotubes (photo with truck). These tubes are a temporary effort to protect houses that are in danger of being damaged by seasonal storms. The tubes can not be moved when filled with sand, eventually degrade and fall apart over time, and pose threats to wildlife in the water and on land. Another measure used to slow erosion are groins made of concrete and placed in the water (photo with truck). These structures cause accelerated erosion in areas right next to them, often making the situation worse.

This beach is also being nourished in the additional photos. A large ship pumps sand from the ocean bottom to the beach. There, the water runs off and the sand is spread out on the beach by heavy equipment. This disrupts plant and animal life on the beach and makes is a very unpleasant place for a walk! The sand often does not match the composition of the sand that is naturally deposited on the beach as evidenced by different colors and grain size.

Fire Island, New York is an excellent example of a developed barrier island that is experiencing natural erosion. This makes Fire Island Beachcare’s Beach of the Month for July 2009.

Sandbagging at the Shore: North Carolina’s Coastal Sand Bags and Political Sandbaggers; By William Neal, Orrin Pilkey & Norma Longo

April 1st, 2017

The wonder of modern English is how social use of language expands and changes the meaning of words. Sand bag is a bag filled with sand used for temporary construction—quickly made, easily transported, and easily removed. Typically, sandbagging is the emplacement of sand bags to construct a temporary protective wall or barrier, such as a dike or dam to hold back flood waters , or protection on the battlefield. But the term ‘sandbagging’ has taken on an array of other meanings…

Changing Beaches, Changing Uses, Mystery Structures: Rosy Mound Park, Lake Michigan, U.S.A; By William Neal, Peter Wampler & Brock Hesselsweet

June 1st, 2016

One of the general rules of beaches is that “no beach stays the same” neither over long reaches or very short stretches nor for very long time intervals. This rule is as true for fresh-water beaches as those of the salty seas. Rosy Mound Natural Area about 2 km south of Grand Haven, Michigan, on the eastern shore of Lake Michigan is a good example.
