Dataset description: q2_1m

Portion of the 1-meter (m) contours in quadrangle 2 of the Stellwagen Bank Survey Area offshore of Boston, Massachusetts based on bathymetry data collected by the U.S. Geological Survey from 1994-1996. This portion of the 1-meter (m) contours that are used in quadrangle 2 Stellwagen Bank geologic interpretation maps that aid in interpretation. The 1-m contours indicate the more hummocky relief of the seabed in areas dominated by gravel deposits and small boulder ridges. The 1-m contours accentuate low-relief topographic complexity in these areas.

Map	quadrangle2_interp_footprint	Footprint of interpretation of the seabed geologic substrates in quadrangle 2 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts based on data collected by the U.S. Geological Survey from 1993-2019. Also represents the footprint of the bathymetry and contour data contributing to the interpretation.
