This line shapefile contains bathymetric contours at 10-meter intervals for the continental shelf and 100 meter intervals beyond the 200 meter shelf edge. The contours have been derived from the National Oceanic and Atmospheric Administration (NOAA), National Geophysical Data Center (NGDC), Coastal Relief Models volume 1 and 2. This data overlay is intended to provide a highly detailed bathymetric contour interval for the New York Bight and Gulf of Maine area. The bathymetric shapefile contains 10 m contours for the continental shelf and 100 m intervals beyond the 200m shelf edge. These contours will be used by the Sand and Gravel assessment project to aid in the interpretation and creation of a geologic map of the sedimentary character of the seafloor for the area. DepthContours10m was derived from USGS and clipped to the northeast region (Top: 48, Bottom: 37, Left: -74, Right:-65). Data values have not been altered from original dataset. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.
