DGS06-1 Bathymetric Elevation Contours Offshore of New Jersey (Ten-Foot Interval)

(13.5MB)

This 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.   

This data is not to be used for navigation. Although this data are of high quality and useful for planning and modeling purposes, they do not necessarily reflect current conditions, nor do they depict data which are on a nautical chart. For navigation please refer to the NOS nautical chart series.

The bathymetry data are prepared for distribution as an ESRI shapefile.  The shapefile is combined with FGDC compliant metadata, layer file and associated database files in a compressed 'zip' file for delivery over the Internet.
