This digital publication may also be available via the web at pubs.usgs.gov Online_Linkage: https://pubs.usgs.gov/of/2003/of03-001/ Description: Abstract: This bathymetric shapefile contains 10 m contours for the continental shelf and 100 m beyond the 200 m 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. Purpose: This data overlay is intended to provide a highly detailed bathymetric contour interval for the NY 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.

The CRM image was then subsetted to create a bathymetry image with values between 11-200 meters and contoured at 10m. The created contours were then thinned by 50% (VECSEL).

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. Added a landing page link as the first link in the identification section. The source information was incomplete and had to be modified to meet the standard. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. Added the online link to the data in the distribution section. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
