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]
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.
27 maj 2019 · Seamounts or underwater volcanic mountains that have a flat top of over 660 feet below the sea surface is referred to as a guyot. The diameter of the flat to may exceed 6.2 miles. Although guyots are common in the Pacific Ocean, they are found in all the world's oceans apart from the Arctic Ocean.
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 · Compared to the peaked shape of seamounts, guyots have a flat top like a table. All guyots will have been a seamount in the past, but not all seamounts will become guyots. Schematic showcasing the difference between a seamount and a guyot Alysha Johnson.
21 gru 2023 · How Were They Formed? Hess speculated that guyots were once volcanic islands that were “beheaded" by wave action or rising oceans. Since then, many researchers have theorized that the flat top was created by wave erosion.
When these flat-topped seamounts eventually sink back down to deep water, they are called guyots. Of all of the seamounts in the Pacific, guyots have the most varied geology and therefore the most varied habitats for animals to live. The base and flanks of a guyot are similar to those found on a conical seamount.
