This data set contains a digitized polygon of the jetty that is present on North End of Assateague Island National Seashore. The hurricane of late August 1933 is notable for turning the Assateague peninsula into an island. Although the inlet is a boon for Ocean City, it has been devastating to north Assateague Island. Prior to the inlet, Assateague received a continual littoral supply of sand from Fenwick Island (the town of Ocean City is on Fenwick Island). Immediately following jetty installation, the rate of recession jumped to 30 to 40 feet per year as the flow of sand was interrupted. Currents into and out of the inlet caused some of the sand to move into the coastal bay during flood tides, depositing most around the oceanside of the inlet during ebb tides, creating the ebb and flood shoals. The shoreline adjacent to the south jetty receded approximately 400 feet from 1935 to 1980. The construction of breakwaters along the north face of the island in the inlet has helped to slow the erosion, and the subsequent sand tightening of the jetties and breakwaters has actually stabilized the first mile of the island. However, the area of critical erosion caused by jetties continues to move southerly along the Island shoreline. In the years since the hurricane, the U.S. Army Corps of Engineers has maintained the jetty of boulders that protects the Ocean City inlet.
The purpose of this data set is to show the location of the South Jetty in the Ocean City Inlet for maps and resource management.
