New Jersey Department of Environmental Protection, New Jersey Geological SurveyThis DGS consists of bathymetric elevation contour lines at ten foot intervals off the New Jersey shore including parts of Delaware Bay, New York Bay, Raritan Bay and Sandy Hook Bay. The bathymetric-elevation contour lines range from -10 feet to -220 feet and extend 20 miles offshore. "Bathymetry" data represents the water depth relative to sea level. The shapefile was created from xyz ASCII grid data obtained from The National Ocean & Atmospheric Administration (NOAA), National Geophysical Data Center (NGDC), Coastal Relief Model Development Program. The data originated from a vast compilation of hydrographic soundings collected by the National Ocean Service (NOS) and various academic institutions.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/e2ffe122276c433dacefc31feb7d8b39_117engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicBathymetric Contours of New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2023-12-27
