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.
History. Guyots were first recognized in 1945 by Harry Hammond Hess, who collected data using echo-sounding equipment on a ship he commanded during World War II. [4] . His data showed that some undersea mountains had flat tops. Hess called these undersea mountains "guyots", after the 19th-century geographer Arnold Henry Guyot. [5] .
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.
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.
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.
Background. Guyots: Intriguing Flat-topped Seamounts that Host a Diversity of Habitats for Deepwater Animals. By Christopher Kelley, Hawaii Undersea Research Laboratory – University of Hawaii. Scott France, University of Louisiana at Lafayette. Large bamboo coral colonies on a guyot ridge.
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.
