Found at 1874 meters depth on the slopes of the Davidson Seamount. [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 Davidson Seamount is located 120 km southwest of Monterey, California. [7][8][9] However, it is believed that they provide a refuge for rare species that have difficulty surviving elsewhere. This underwater goliath lies 75 miles west of San Simeon, Ragged Point and Gorda, stretching 26 miles long and 8 miles wide. Rising up 2,280 meters from the seafloor, the Davidson Seamount, an underwater mountain, is an unlikely “oasis in the deep.” ... grows to over three meters in height … In 2008, Monterey Bay National Marine Sanctuary was expanded to protect it. Davidson Seamount is a seamount (underwater volcano) located off the coast of Central California, 80 mi (129 km) southwest of Monterey and 75 mi (121 km) west of San Simeon.Being 26 mi (42 km) long and 8 mi (13 km) wide, it is one of the largest seamounts in the world. Although these species also grow elsewhere, they are generally sparsely distributed and far smaller and younger than the coral growth on Davidson. [5], Davidson Seamount is part of a group of seamounts off the continental margin, including Guide, Pioneer, Gumdrop, and Rodriguez seamounts, all located roughly between 37.5° and 34.0° degrees of latitude. Grenadier fish (Coryphaenoides sp.) The seamount is an inactive volcano roughly as tall as the Sierra Mountains (2,300 m) and as wide as Monterey Bay (40km), yet its summit is far below the ocean surface (1,300 m).

Fly-trap anemone (Family: Hormathiidae) on the slope of the Davidson Seamount at 1,874 m. Number of Corals Identified at Designation. The Davidson Seamount is one of the largest in U.S. waters. Jim, the marine ecologist, studies life on the rocks that David pulls up from the deep. [4], Davidson Seamount is among the best biologically described seamounts worldwide. A seamount is a large geologic landform that rises from the ocean floor but that does not reach to the water's surface (), and thus is not an island, islet or cliff-rock.Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height. Related Links Yet its summit is still more than 4,000 feet below the sea surface. in front of bubblegum coral (Paragorgia arborea) on the crest of Davidson Seamount, at 1,255 m (4,117 ft) deep. Discovered during the mapping of California's coast in 1933, Davidson Seamount is named after geographer George Davidson of the U.S. National Geodetic Survey. An underwater mountain, it was the first undersea feature to be characterized as a “seamount,” in 1938. Davidson is interesting to volcanologists because of its unique geology, and to biologists for its unique ecology. The team included scientists, educators, and resource managers, with the goal of documenting species, taking geologic samples, and describing the ocean environment. [8], The seamount is populated by a large variety of deep-sea corals, most of which in turn provide a habitat for other species. The underwater mountain rises 8,000 feet above the ocean floor, relatively the same height … The seamounts are likely to be a source of larvae that maintains the population of the species in nearby, sub-optimal areas, known as "sinks."
