2021 Map of Squibnocket OE S

About this map

Nantucket Shoals dominate this maritime expanse, marking a significant navigational area south of Martha's Vineyard. This 2021 chart, produced by the U.S. Geological Survey, focuses almost entirely on the open waters of the Atlantic Ocean. The data provided by the National Hydrography Dataset and National Elevation Dataset delineates the underwater topography and hazard-prone shallows that have defined coastal transit in this region for centuries. As a modern survey of the Squibnocket offshore area, it captures the current state of the shifting seabed and maritime boundaries without the distraction of terrestrial settlements or landforms.
