marine charts
Ocean navigation guides
Marine charts are specialized maps designed for navigation on water, showing coastlines, water depths, underwater hazards, currents, and navigational aids like buoys and lighthouses.
Unlike land maps, they emphasize what lies beneath the surface and at the water's edge.
Mariners rely on them to plot safe courses and avoid running aground: The captain consulted the marine chart before entering the harbor.
