Ocean Shoal

Published by opendata.maryland.gov | State of Maryland | Catalog Last Checked: June 23, 2026 at 07:22 PM | Dataset Last Updated: June 17, 2026
These are shoal boundaries off the coast of Maryland created by the Maryland Geological Survey (MGS). No formal metadata was received, but MGS describes the data as generalized polygon outlines, mostly qualitative assessments of where the thickness of the sand body pinches out to less than 1 meter thickness over the underlying revinement surface. In some cases it is the 60 foot contour, where there is no seismic data.
