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 ...
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April – 4 May 2019). The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor.
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions.It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on the definition, to Antarctica) in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
Continental shelves appear mostly by a depth of 140 meters, mid-ocean ridges by 3000 meters, and oceanic trenches at depths beyond 6000 meters. 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 ...
Initially, the effort's name was the Pacific Ocean Ornithological Project; however, it was changed once someone noted the natural acronym "POOP". [57] First isolated in 1964 the tick -borne virus was discovered in Ornithodoros capensis ticks, found in a nest of common noddy ( Anous stolidus ) at Sand Island, Johnston Atoll.
Satellite imagery released on Monday has provided visual evidence of new findings that the global ocean is hotter than ever. The average global ocean temperature is now 21.1 degrees Celsius ...
False color map of ocean depth in the Atlantic basin (from Atlantic Ocean) Image 46 "Terres Australes" [sic] label without any charted landmass (from Southern Ocean ) Image 47 The Antarctic Circumpolar Current (ACC) is the strongest current system in the world oceans, linking the Atlantic, Indian and Pacific basins.
TOPEX/Poseidon was the first space mission that allowed scientists to map ocean topography with sufficient accuracy to study the large-scale current systems of the world's ocean. Although this image was constructed from only 10 days of TOPEX/Poseidon data (October 3 to October 12, 1992), it reveals most of the current systems that have been ...
