Station M is a long-term study site on the abyssal plain, about 220 kilometers (140 miles) off the Central California coast and 4,000 meters (13,100) feet below the ocean surface. This zone covers all from tidal pools and continental shelves to abyssal depths. The plain is generally 13,000 to 20,000 ft (4,000 to 6,000 m), extending seaward from the base of a continental slope or from the seaward edge of an oceanic trench to the midocean ridge. Squid, octopi, echinoids, worms, mollusks and fish all live in the abyssal zone and survive by feeding on organic matter that floats down from higher zones. Instead, tiny microbes, known as cormophytes, act as producers in this zone by resorting to the process of chemosynthesis and oxidizing hydrogen sulfide coming from vents in the ocean floor.

The abyssal sediment in waters below 4,000 m in equatorial regions is mainly formed from the calcareous shells of foraminiferous zooplankton and phytoplankton, known as coccolithophores. abyssal plain trench. Giant Squid (Architeuthis dux) Yes, animals can live in the abyssal plain. The intertidal zone is an extreme ecosystem because it constantly experiences drastic changes. Squid, octopi, echinoids, worms, mollusks and fish all live in the abyssal zone and survive by feeding on organic matter that floats down from higher zones. abyssal plain. Because food is scarce, they have large gaps, so they can eat any food possible. The abyssal zone has temperatures ranging from 2-3 °C (35-37 °F). Abyssal Plain. ✦ As there is no sunlight to support the process of photosynthesis, the Abyssal Zone is devoid of plants.

The abyssal zone is saturated with nutrients, such as nitrogen, phosphorous and silica, of decayed organic matter from the waters above. The abyssal sea floor at 4,000 meters of depth and shallower regions is composed of calcareous shells of zooplankton and phytoplankton. -The usual temperature in the Abyssal Plain is 0 to -4 degrees Celsius but it can get up to 464 degrees Celsius near hydrothermal vents. Abyssal plains – Abyssal plains are defined by the IHO (2008) as “An extensive, flat, gently sloping or nearly level region at abyssal depths.” Sediment deposited adjacent to the continents forms the continental rise. Abundance and diversity decrease with increased water depth and distance from the shoreline, a result of dwindling food availability, increased pressure, and decreasing water temperatures. however organic matter is not abundant at the botttom of a abyssal plain.

An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). The level under that is the Abyssopelagic/Abyss Zone, which has close to freezing temps, no light whatsoever, and very high pressure. Abyssal plain is a submerged plain on the profound sea depths, generally found at profundities somewhere around 3000 and 6000 m. Lying for the most part between the foot of a mainland rise and a mid-sea edge, deep fields cover more than half of the Earth's surface. Base image: Google Earth.
