Bathymetric Contours for the Gulf of Maine Sea Floor

A 2006 data set provides bathymetric contours for the Gulf of Maine and New England Shelf. The U.S. Geological Survey constructed it for geologic framework studies. It was reprojected into the NAD83 Massachusetts State Plane coordinate system by the Massachusetts Office of Coastal Zone Management.

Use Cases

• Modeling sea floor terrain and slope from bathymetric contour lines for habitat suitability studies.
• Integrating bathymetric contours with other geologic data layers for resource assessment frameworks.
• Providing a foundational geospatial layer for environmental impact studies in the Gulf of Maine project area.

Strengths

• Data originates from the authoritative U.S. Geological Survey sea floor geology studies.
• Contours are reprojected into a standardized coordinate system (NAD83 / Massachusetts State Plane Mainland Zone).

Limitations

• Data currency is limited, with a noted reprojection date in June 2006, indicating potential staleness.
• Specific spatial resolution, point density, and vertical accuracy of the source bathymetric data are not provided.
