Continental shelf seabottom gravity survey: Cape Hatteras, North Carolina - Cape May, New Jersey

One hundred seventy three sea-floor gravity stations spaced over an area of approximately 4800 nm 2 were occupied on the continental shelf between Cape Hatteras, North Carolina and Cape May, New Jersey through the cooperative efforts of the U.S. Department of Commerce, Environmental Science Services Administration and the U.S. Department of Defense, Naval Oceanographic Office. A sea-surface gravity equipment test range covering an area of approximately 500 nm near the Chesapeake Bay entrance was established as part of a larger continental shelf gravity program in the area of the offshore extension of the Transcontinental Geophysical Survey. Sea-floor gravity stations were occupied at 1.5 to 5 nm intervals in the test range area and at 10 nm intervals elsewhere. This report summarizes the operation and presents tabulated gravity data outside the test range. A free-air anomaly contour map of the combined areas as well as adjacent land gravity data is presented.
