ocean map
Mariner's navigation tool
An ocean map is a chart depicting seas, their depths, currents, and features.
Unlike land maps that show terrain and borders, ocean maps emphasize bathymetry (underwater topography), shipping lanes, and navigational hazards.
They range from ancient portolan charts used by sailors to modern digital maps showing real-time conditions: The ocean map revealed a submarine canyon we hadn't expected.
