Bathymetric Contours for New York Bight and Gulf of Maine

June 26, 2006 bathymetric shapefile contains 10-meter depth contours for the continental shelf and 100-meter contours beyond the 200-meter shelf edge. The data was derived from NOAA National Geophysical Data Center Coastal Relief Models and reprojected by the Massachusetts Office of Coastal Zone Management. The dataset covers the New York Bight and Gulf of Maine regions.

Use Cases

• Modeling seafloor terrain using 10 m and 100 m contour intervals for hydrodynamic simulations.
• Analyzing continental shelf extent and slope using the 200 m shelf edge contour line.
• Integrating bathymetric contours with other marine datasets using the NAD83 / Massachusetts State Plane coordinate system.

Strengths

• Contains high-resolution 10-meter contour intervals for detailed shelf analysis.
• Includes contours extending 100 meters beyond the 200-meter shelf edge for broader context.
• Data was reprojected into a standardized coordinate system (NAD83 / Massachusetts State Plane) for consistency.

Limitations

• Specific row count, file size, and total geographic area covered are unknown.
• Data was processed in 2006 and may not reflect recent seafloor changes or surveys.
• Original data source details and potential limitations from the NOAA NGDC models are not described.
