An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. The word abyss comes from the Greek word ἄβυσσος ( ábussos ), meaning "bottomless". [ 1 ] At depths of 4,000–6,000 m (13,000–20,000 ft), [ 2 ] this zone remains in perpetual darkness.
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.

To find it again, researchers from Utrecht University used geological information from a deep ocean basin off western Australia—the Argo Abyssal Plain—to uncover clues about what could have ...
For research purposes, the Madeira Abyssal Plain can be divided into three sub-basins. They are a southern sub-basin, which lies at a water depth of about 5,350 meters (17,550 ft), a central sub-basin which lies at a deeper water depth of about 5,440 meters (17,850 ft), and the northern sub-basin which lies at an intermediate water depth of about 5,420 meters (17,780 ft).
Because the continental rise lies below the continental slope and is formed from sediment deposition, it has a very gentle slope, usually ranging from 1:50 to 1:500. [1] As the continental rise extends seaward, the layers of sediment thin, and the rise merges with the abyssal plain, typically forming a slope of around 1:1000.

It was also known [when?] as the Argo Plain; another suggested [by whom?] name is the Argo Abyssal Plain. It was discovered by the U.S. research vessel "Argo" of the Scripps Institution of Oceanography in 1960. [1] It should be distinguished from an Australian sedimentary basin with the same name. [2] [3]
