Like conical seamounts, the base and flanks of a guyot have ridges that may accommodate high-current dwelling filter-feeding corals and sponges, and canyons formed by flank failures that accommodate calmer-water fishes and invertebrates.
guyot, isolated submarine volcanic mountain with a flat summit more than 200 metres (660 feet) below sea level. Such flat tops may have diameters greater than 10 km (6 miles). (The term derives from the Swiss American geologist Arnold Henry Guyot.)
7 sty 2021 · The seamounts provide vital habitat for marine invertebrates like brittle stars and squat lobsters to live on and act as nurseries for deep-sea fish. The seamounts also influence the flow of deeper waters, which results in the upwelling of nutrient-rich waters towards the sea surface.
In marine geology, a guyot (/ ˈ ɡ iː. oʊ, ɡ iː ˈ oʊ /), [1] [2] also called a tablemount, is an isolated underwater volcanic mountain with a flat top more than 200 m (660 ft) below the surface of the sea. [3]
21 gru 2023 · Guyots are isolated underwater volcanic mountains. They are distinctive from other submarine mountains and underwater volcanoes (seamounts) because of their flat tops (some are measured up to six miles in diameter) as well as evidence that they were once above sea level.
Guyots and atolls. A guyot is a flat-topped submarine mountain, or seamount, that once emerged above sea level as a volcanic island, and then resubmerged when volcanic activity ceased. Erosion by wave activity during submergence creates the characteristic flat-topped profile of a guyot.
