W.D. Leeds Robin Bell J. A. Grow D. R. Hutchinson 1986 <p>The U.S. Geological Survey (USGS) has collected marine gravity data along the U.S. Atlantic continental margin during the last decade. This map of the Long Island platform combines the data used to make the preliminary free-air gravity anomaly map of the Atlantic continental margin (Grow and others, 1976) with the new gravity values collected aboard the RV <i>Gilliss</i> in 1979 and the RV <i>Gyre</i> in 1981.</p> <p>Carl Bowin provided the USNS <i>Kealthley</i> data from the Woods Hole Oceanographic Institution gravity data-base. We thank Bab Bowles (USGS) for his advice on editing the navigation and gravity data.</p> application/pdf 10.3133/mf1807 en U.S. Geological Survey Free-air gravity anomaly map of the Long Island Platform reports
