ocean mapping
Surveying underwater terrain
Ocean mapping is the systematic surveying and charting of the seafloor and underwater features.
It encompasses measuring depth (bathymetry), identifying underwater terrain like trenches and seamounts, and documenting geological and biological characteristics.
Modern ocean mapping relies on sonar, satellites, and remote-operated vehicles: Less than a quarter of the ocean floor has been mapped in detail.
The data supports navigation, resource exploration, and marine conservation.
