2014 Map of Machias Seal Island South

USGS Topo · Published 2014

About this map

Machias Seal Island occupies the northern margin of this maritime survey, marking a small but significant landmass in the waters of the Gulf of Maine. This 2014 chart focuses heavily on the open ocean and submerged terrain south of the island, including the area near Southeast Shoal. Because the map covers a portion of the coastline subject to international maritime boundary discussions between the United States and Canada, the absence of extensive terrestrial features highlights the area's isolation and its primary character as a navigational and ecological zone. The map provides a detailed coordinate grid for the waters extending south toward the open Atlantic, a region defined by its seafloor topography and its distance from the mainland of Washington County.
