Atlantic Ocean waters dominate this maritime chart, providing a high-resolution look at the submerged topography and coastal outcrops southeast of the Rockport peninsula. While mostly comprised of open sea, the survey captures the hazardous navigational features of the Cape Ann shoreline, specifically the rocky projection of Salt Island and the neighboring Salt Island Ledge. Further offshore, the mapping identifies the significant seafloor rise of Gloucester Bank, an area historically tied to the region's deep-sea fishing heritage. This 2012 record serves as a precise digital capture of these bathymetric and coastal landmarks before shifting coastal dynamics or rising sea levels alter the profile of the North Shore's outer islands.
