sea maps
Ocean navigation guides
Sea maps are charts showing maritime features—coastlines, depths, currents, hazards, and navigation routes.
The term is less technical than nautical chart or marine chart, often appearing in historical or literary contexts: Ancient sea maps depicted monsters at the ocean's edges.
Sea maps may also refer to any cartographic representation of ocean areas.
