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 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 ...
Using the remotely operated vehicle SuBastian, researchers exposed parts of the subseafloor and uncovered a surprise: caves connected to the vents teeming with giant tube worms, some reaching up ...
The first quarter-mile of the cave was known to local ranch-hands by the early 1900s. It was known by the name Mayfield Cave, after the landowner, Stanley Mayfield. [4] In 1955, Stanley gave permission to four cavers from Dallas, who discovered a further seven miles, including what are now considered the most scenic areas.
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 ...
Light from a remotely operated vehicle reveals a “huge” crowd of sea urchins, gathered in the dark roughly 1,350 feet below the surface, all wearing “hats,” made of debris, on the tops of ...
Seafloor massive sulfide sample collected from the Magic Mountain hydrothermal field, British Columbia, Canada. Seafloor massive sulfide deposits or SMS deposits, are modern equivalents of ancient volcanogenic massive sulfide ore deposits or VMS deposits. The term has been coined by mineral explorers to differentiate the modern deposit from the ...
Deepsea Challenger (DCV 1) was a 7.3-metre (24 ft) deep-diving submersible designed to reach the bottom of the Challenger Deep, the deepest-known point on Earth.On 26 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal in the second crewed dive reaching the Challenger Deep.
