Oceans Act of 2008: Offshore Management Planning Area

This GIS layer shows the extent of the Massachusetts coastal ocean governed by the Massachusetts Oceans Act of 2008. The polygon layer was created by merging three arc layers: the Submerged Lands Act line administered by the Minerals Management Service, the presumed Massachusetts lateral boundaries, and the Nearshore Ocean Management Planning Area Boundary created by the Massachusetts Office of Coastal Zone Management (CZM). The area closed by these three lines was converted into a polygon by CZM July 18, 2008.
