About this map

The Atlantic Ocean dominates this maritime survey off the southern coast of Martha's Vineyard. This area is defined by the submerged hazards of Nantucket Shoals, a complex system of shifting sandbars and shallow waters that have influenced navigation in these coastal reaches for centuries. The map focus is almost entirely offshore, providing a look at the bathymetry and sea conditions south of the island in Dukes County. This specific perspective highlights the isolation of the shoals as they extend into the open sea, away from the settled harbors of the mainland and islands. The minimal terrestrial features reflect the nautical nature of this quadrangle, serving as a specialized record of the underwater topography in this part of the Massachusetts shoreline.
