Abstract:

Spit-bars, representing stages in the historical development of a prograding shoreline, were mapped at Horseshoe Cove, Sandy Hook, New Jersey. both photogrammetric and field surveying methods were used. An offshore bar, genetically related to the foreshore spip-bars and extending westward into Sandy Hook Bay, was mapped by transit and theodolite. Mechanical analysis of the relatively fine sand of the offshore bar showed all samples to be well sorted but with an arithmetic mean diameter increasing shoreward. Eleven sets of vertical aerial photographs covering the period 1947 through 1961 and radial and transverse profiles taken during the 1959, 1960, and 1961 summer field seasons were analyzed. Retrogradation of the northwest-facing shoreline progressed at an average rate of 11.5 feet per year. From instrument station S-1 through E progradation occurred at an average rate of 9.0 feet per year. The shoreline between S-7 and F is a fulcrum zone where only minor changes in shoreline position occurred over the period of study. Author
