16 cze 2024 · A guyot, or seamount, is an undersea mountain. A sonar image of a guyot, or seamount, in the Arctic. Using a multibeam echo sounder, NOAA scientists can map and produce a visualization from the data collected of the bottom of the ocean.

This thick covering hosts a different suite of animals than are found on the steeper, hard flanks of the guyot: sediment-dwelling shrimps, isopods, crabs, sea stars, brittle stars, sea cucumbers, sea pens, worms of various kinds, and even a few species of sponges.
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.) In the Pacific Ocean, where guyots are most.
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.
Life on Resolution Guyot included algae – both green and red algae and species forming microbial mats –, bivalves including rudists, bryozoans, corals, echinoderms, echinoids, foraminifera, gastropods, ostracods, oysters, serpulid worms, sponges and stromatoliths. Fossils of animals have been found in the drill cores.
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.
