The Bear Seamount (left), a guyot in the northern Atlantic Ocean. 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]
A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (), and thus is not an island, islet, or cliff-rock.Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
However, some ocean island basalt locations coincide with plate boundaries like Iceland, which sits on top of a mid-ocean ridge, and Samoa, which is located near a subduction zone. [ 2 ] In the ocean basins, ocean island basalts form seamounts , [ 3 ] and in some cases, enough material is erupted that the rock protrudes from the ocean and forms ...
The seamount is located just 2.3 degrees north of the bend. [2] Much of what we know about Koko comes from early dredgings and the Ocean Drilling Program's core samples, collected as part of Leg 197, at Site 1206, which aimed to supply information on the relatively obscure Emperor seamounts and study their relation to the Hawaiian chain.

Scientists thought that Lake Enigma was frozen from top to bottom. Then they discovered that water—and mysterious lifeforms—existed 11 meters below the surface.
