The Bear Seamount, a guyot. A guyot, also known as a tablemount, is an isolated underwater volcanic mountain ( seamount ), with a flat top over 200 metres (660 feet) below the surface of the sea. The diameters of these flat summits can be more than 10 km (6.2 mi).
A guyot is an underwater mountain or seamount with a flat top. This geologic feature is also called a tablemount. In general, the guyot or tablemount is over 200 meters (660 feet) below the surface of the sea. The diameters of these flat underwater summits may be more than 10 km (6.2 mi).
History. The existence of flat-topped mountains below the surface of the ocean was established in 1965. Harry Hammond Hess used echo-sounding equipment to map the floor of the ocean. The research revealed that some undersea mountains had flat tops.
24 wrz 2024 · Arnold Henry Guyot was a Swiss-born American geologist, geographer, and educator whose extensive meteorological observations led to the founding of the U.S. Weather Bureau. The guyot, a flat-topped volcanic peak rising from the ocean floor, is named after him. He studied at the College of Neuchâtel.
Early life. Guyot was born on September 28, 1807, at Boudevilliers, near Neuchâtel, Switzerland. He was educated at Chaux-de-Fonds, then at the college of Neuchâtel. In 1825, he went to Germany and resided in Karlsruhe where he met Louis Agassiz, the beginning of a lifelong friendship.
A guyot is a flat topped seamount. Guyots show evidence of having been above the surface with gradual subsidence through stages from fringed reefed mountain, coral atoll, and finally a flat topped submerged mountain.
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.
