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.
IBCSO is a joint project by the International Hydrographic Organization, the Scientific Committee on Antarctic Research, the General Bathymetric Chart of the Oceans and the Seabed 2030 Project. The project aims to identify and pool all Bathymetry data in the Southern Ocean and use that data to produce gridded bathymetric maps of the seafloor.
World ocean bathymetry. Physical oceanography is the study of physical conditions and physical processes within the ocean , especially the motions and physical properties of ocean waters. Physical oceanography is one of several sub-domains into which oceanography is divided.
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.
Marine geology or geological oceanography is the study of the history and structure of the ocean floor. ... EM300 bathymetry of the three submarine volcanoes in the ...
This ocean depth spans from the edge of the continental shelf down to the top of the abyssal zone, and along continental slope depths. [2] [4] The bathymetry of the bathypelagic zone consists of limited areas where the seafloor is in this depth range along the deepest parts of the continental margins, as well as seamounts and mid-ocean ridges.
