- Abstract:
-
This shapefile represents major canyons of the Mid-Atlantic Coast. Approximate boundaries were heads-up digitized over a raster bathymetry layer. Canyon names come from NOAA charts and other various sources. These boundaries were created primarily for cartographic purposes and in no way represent ecological boundaries. Updated in March, 2020 to more closely match Lautenberg Deep Sea Coral Protection Area where appropriate, add additional canyons, and also to better match high resolution NCEI multibeam bathymetry.
- Purpose: Created primarily for cartographic and planning purposes.

-
Canyon names were gleaned from NOAA charts and other maps in various reports.
- Completeness_Report:
-
This is a representation of most canyons considered to be "major canyons" by a number of different sources. However there are many smaller canyons that are not included and ultimately what is included here is based on somewhat subjective criteria.
