Bathymetry (/ b ə ˈ θ ɪ m ə t r i /; 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.
The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.
The most recent version is also incorporated into the annual release of the General Bathymetric Chart of the Oceans grid. The first version of IBCSO was published in 2013, [4] covering the Southern Ocean south of 60°S. More than 4,200 million ocean soundings of diverse types and quality were incorporated.
Satellite-derived bathymetry (SDB) is the calculation of shallow water depth from active or passive satellite imaging sensors. The technology requires a sensor (hardware) and relevant algorithms (software) to derive bathymetric measurements from the data recorded by the sensor.

Bathymetry of the Kerguelen Plateau Location of the plateau – the white spot is Kerguelen Island. The Kerguelen Plateau (/ ˈ k ɜːr ɡ əl ən /, / k ər ˈ ɡ eɪ l ən /), [1] also known as the Kerguelen–Heard Plateau, [2] is an oceanic plateau and large igneous province (LIP) located on the Antarctic Plate, in the southern Indian Ocean.
