Guyots

 

(named after their discoverer, the American geographer and geologist A. Guyot, 1807-84), isolated, flat-topped, underwater volcanic mountains. They are found primarily in the Pacific Ocean in groups or as solitary peaks. There are also solitary guyots in the Atlantic and Indian oceans. Their peaks are located at depths of 200-2,000 m. It is thought that they were leveled by abrasion. Since abrasion is evident only up to depths on the order of 100-200 m, it is suggested that the majority of guyots underwent a subsidence together with the ocean floor that forms their base.

Sea caves, probably produced by wave erosion when the guyot drowned, are common, particularly at the bases of the pinnacles and ridges, strongly suggesting the summit itself is a product of wave truncation.
This area represents about 25% of the suitable habitat for both species on the guyot summit.
