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 ...
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.

After the Mediterranean Sea, the Caribbean Sea is the second-most-polluted sea. Pollution in the form of up to 300,000 tonnes of solid garbage dumped into the Caribbean Sea each year is progressively endangering marine ecosystems, wiping out species, and harming the livelihoods of local people, who rely primarily on tourism and fishing.
The relatively narrow trough trends east-northeast to west-southwest and has a maximum depth of 7,686 metres (25,217 ft). Within the trough is a slowly spreading north–south ridge which may be the result of an offset or gap of approximately 420 kilometres (260 mi) along the main fault trace.
Stewart and Jamieson also reported a maximum depth of 8,408 m (27,585 ft; 4,598 fathoms) [12] in 2019 and 8,378 m (27,487 ft; 4,581 fathoms) [13] in 2021.

The daughter of a diving instructor growing up in Mexico, Ms Rojas had already developed a passion for the ocean and underwater exploration when she saw an old black-and-white movie about Titanic.
The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 10,994 m (36,070 ft) below sea level. Oceanic trenches are a feature of the Earth's distinctive plate tectonics.
