The Nippon Foundation-GEBCO Seabed 2030 Project, which aims to motivate a number of collaborators to create a full map of the ocean floor, was launched in 2016. [5] There are four Seabed 2030 centres, which coordinate mapping activities in different regions, gather and compile the bathymetric information, and partner with existing mapping ...
A seafloor map captured by NASA. 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 ...
The Great Blue Hole, located near Ambergris Caye, Belize Dean's Blue Hole, Long Island, Bahamas Watling's Blue Hole, San Salvador Island, Bahamas. A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock (limestone or coral reef).
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 meters (9,800 ft) and 6,000 meters (20,000 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains are among the flattest, smoothest and least explored regions on Earth.

An ocean-bottom seismometer (OBS) is a seismometer that is designed to record the earth's motion under oceans and lakes from man-made sources and natural sources.. Sensors at the sea floor are used to observe acoustic and seismic events.

At the spreading center on a mid-ocean ridge, the depth of the seafloor is approximately 2,600 meters (8,500 ft). [2] [3] On the ridge flanks, the depth of the seafloor (or the height of a location on a mid-ocean ridge above a base-level) is correlated with its age (age of the lithosphere where depth is measured).
