Initiated in 2008, the CSMP has collected bathymetry (underwater topography) and backscatter data (providing insight into the geologic makeup of the seafloor) that are being turned into habitat and geologic base maps for all of California's State Waters (mean high water line out to three nautical miles). In other words, bathymetry is the underwater equivalent to hypsometry or topography. They show the shape and slope of the ocean bottom surface. Made of waterproof, tear resistant plastic. Bathymetric maps look a lot like topographic maps, which use lines to show the shape and elevation of land features. It’s largely thanks to satellite altimetry over the ocean surface, which is subtly shaped by the topography below, that we have the seafloor maps we’re accustomed to seeing in textbooks.

Under the South Pacific lies the lost underwater continent of Zealandia, which new maps reveal in greater detail than ever seen. roads and trails, railroads, boundaries, and other cultural features (black). Underwater topography, also known as bathymetry, is the study of topography of the deep floors under oceans, seas, and lakes. The surface of the ocean is a good approximation to the marine geoid. Shifts in the seafloor can trigger tsunamis, as shown by this year’s disaster in Japan, and the 2004 wave that swept Sumatra. De très nombreux exemples de phrases traduites contenant "underwater topography" – Dictionnaire français-anglais et moteur de recherche de traductions françaises.

Bathymetric maps (a more general term where navigational safety is not a concern) may also use a Digital Terrain Model and artificial illumination techniques to illustrate the depths being portrayed. Most areas of the oceans are uncharted because ships could map only a small fraction of the seafloor. Examples of symbols that have changed include built-up areas, roads, intermittent drainage, and some lettering styles. geophysical data for the Continental Shelf and slope.
