A topographic map of the floor of the sea is known as what?

Underwater terrain is described by bathymetry, the measurement and depiction of depths below the ocean surface. A bathymetric map shows the sea floor’s relief using depth measurements, typically with contour lines and color shading to represent different depths. It functions as the counterpart to a land topographic map, which shows elevations on land. While nautical charts focus on navigation and may include depth information, their primary purpose isn’t to map the sea floor’s terrain. Hydrographic maps cover broader water-body measurements and features, whereas the specific depiction of sea-floor relief is best described as bathymetry. Therefore, the topographic map of the sea floor is a bathymetric map.
