2024 Map of Rockport OE S

About this map

Salt Island and the neighboring Salt Island Ledge stand as the primary coastal markers on this maritime-focused survey of the waters off Essex County. The map is almost entirely dominated by the Atlantic Ocean, illustrating the bathymetric and navigational context of the Cape Ann region. The presence of Gloucester Bank highlights the submarine topography that has historically supported the region's fishing industry and maritime economy. Because the sheet focuses on the open water and immediate offshore features, it serves as a precise record of the shoreline's edge and the hazards or landmarks known to local mariners in the early twenty-first century.
