GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...
Bathymetric charts showcase depth using a series of lines and points at equal intervals, called depth contours or isobaths (a type of contour line). A closed shape with increasingly smaller shapes inside of it can indicate an ocean trench or a seamount, or underwater mountain, depending on whether the depths increase or decrease going inward. [2]
Some symbols describe the sea bed with information such as its depth, materials as well as possible navigational hazards such as shipwrecks. Other symbols show the position and characteristics of navigational aids such as buoys , lights , lighthouses , coastal and land features and structures that are useful for position fixing .
OpenSeaMap measures water depths by crowdsourcing. Sailors, motor boaters, divers, and fishermen can collect water depths between 0 and 100 m with sounder tools and GPS. Divers work with a dive computer. Coastal water, lakes and rivers are surveyed. Result will be an elevation model and derived depth lines.

Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern/Antarctic; the last two listed are sometimes consolidated into the first three.
