A seafloor map captured by NASA. Bathymetry ( / bəˈθɪmətri /; from Ancient Greek βαθύς (bathús) 'deep' and μέτρον (métron) 'measure') [ 1][ 2] is the study of underwater depth of ocean floors ( seabed topography ), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography.
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. Topographic maps display elevation above ...

It offers satellite imagery, aerial photography, street maps, 360° interactive panoramic views of streets (Street View), real-time traffic conditions, and route planning for traveling by foot, car, bike, air (in beta) and public transportation.
The Black Sea undersea river is a current of particularly saline water flowing through the Bosphorus Strait and along the seabed of the Black Sea. The discovery of the river, announced on 1 August 2010, was made by scientists at the University of Leeds, and is the first of its kind in the world. [ 1] The undersea river stems from salty water ...
Lighthouse Reef as seen from space. The Great Blue Hole is near the center of the photograph. The Great Blue Hole is a giant marine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km (43 mi) from the mainland and Belize City. The hole is circular in shape, 318 m (1,043 ft) across and 124 m (407 ...
The Great Barrier Reef is the world's largest coral reef system, [ 1][ 2] composed of over 2,900 individual reefs [ 3] and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). [ 4][ 5] The reef is located in the Coral Sea, off the coast of Queensland, Australia ...
Animation of circulation around ice shelves of Antarctica. An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. [ 1]
Salt. The Blue Hole is a diving location on the southeast Sinai, a few kilometres north of Dahab, Egypt on the coast of the Red Sea . The Blue Hole is a submarine sinkhole, with a maximum depth within the hole of just over 100 m (328 feet). There is a shallow opening to the sea around 6 m (20 feet) deep, known as "the saddle", and a 26 m (85 ...
