Deep-water coral Paragorgia arborea and a Coryphaenoides fish at a depth of 1,255 m (4,117 ft) on the Davidson Seamount. The habitat of deep-water corals, also known as cold-water corals, extends to deeper, darker parts of the oceans than tropical corals, ranging from near the surface to the abyss, beyond 2,000 metres (6,600 ft) where water temperatures may be as cold as 4 °C (39 °F).
Paragorgia arborea is a species of coral in the family Paragorgiidae, commonly known as the bubblegum coral because of its bulbous branch tips. It mainly grows in depths between 200 and 1,300 metres (700 and 4,300 ft) at temperatures between 3 and 8 °C (37 and 46 °F).
Madrepora oculata, also called zigzag coral, is a stony coral that is found worldwide outside of the polar regions, growing in deep water at depths of 50 to at least 1500 meters. [2] It was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae . [ 3 ]
The coral mounds extend across much of the Blake Plateau, an area between the North American continental shelf and the deep ocean basin along the southeastern U.S. up to North Carolina.
Scientists have mapped the largest coral reef deep in the ocean, stretching hundreds of miles off the U.S. Atlantic coast. While researchers have known since the 1960s that some coral were present ...
Studies have indicated that a seamount functions as an "oasis of life," with a higher species count and more biodiversity than the surrounding seafloor. [4] Although previous analysis has stressed the exceptionalism of the seamount habitat, recent biological analysis, much of it centered on Davidson Seamount, has indicated that this does not necessarily translate into a higher endemic percentage.
The Miami Terrace and other areas of deep sea coral can be damaged by certain kinds of fishing gear such as bottom trawling or dredging. [8] Areas on the Miami Terrace and a series of biogeographically similar areas were approved in 2004 for protection from these activities through the South Atlantic Fishery Management Council but were never finalized.
On a recent expedition, a group of ocean researchers discovered 85 miles of deep-sea coral reef off the coast of the southeastern US.
