An isolated, tall mountain on the seafloor that may extend more than 1 km from base to peak.
an isolated underwater mountain of volcanic origin, rising more than 1,000 m above the ocean floor and usually 1,000 to 2,000 m below the ocean surface.
Conical mountain rising 1000 m or more above the sea floor.
An elevation of the seafloor, 1000 m or higher, either flat-topped (called a guyot) or peaked (called a seapeak).
underwater mountain with a round, pointed or irregular top
A conical underwater mountain formed by a volcano and rising 1000 meters or more from the sea floor.
An undersea mountain rising a minimum of 1000 meters from the ocean floor.
a large, isolated and underwater elevation characteristically conical in form.
a not-quite island, an underwater mountain without enough oomph to make it to sea level
an underwater volcano that plateaus below the surface of the sea
a volcano that rises from the seabed but does not emerge above the surface of the water
Isolated, submarine volcano
an isolated, steep-sided, peak on the seafloor usually caused by volcanic activity. Generally, seamounts rise at least 1000m, though biologists often include shorter submarine peaks.
an isolated mountain situated on the sea floor.
A submarine volcano.
A mountain on the sea floor that has at least 1000 meters of local relief. Most seamounts are shield volcanoes. (See also Guyot.)
An isolated submarine mountain.
a submarine mountain rising 1,000 meters or more above the sea floor.
An undersea mountain rising over 1000 meters above the surrounding seafloor.
A peak rising from the seafloor that does not break the surface.
A seamount is an underwater mountain that rises at least 1000 meters above the sea floor. Some seamounts rise above the water's surface. Most seamounts are volcanic in orgin; only a few are non-volcanic (caused by uplifting). Seiche (saysh): a series of standing waves (sloshing action) of an enclosed body or partially enclosed body of water caused by earthquake shaking. Seiche action can affect harbors, bays, lakes, rivers, and canals.
an elevation rising generally more than 1,000 meters and of limited extent across the summit SMU
An isolated volcanic peak that rises at least 3280 feet (1000 m) from the seafloor.
an extinct, underwater volcano that rises more than 1 km above the seafloor but whose peak is below the sea surface.
An individual peak extending over 1000 m above the ocean floor.
a submarine mountain rising above the deep sea floor
Peaks of undersea mounds which can extend several hundred metres above the sea bottom, often capped with corals (known as carbonate mounds).
Isolated undersea mountain (usually a volcano) with the summit lying well below the ocean surface.
An extinct volcano which has been eroded by ocean waves, resulting in a flat-topped feature just beneath the surface of the ocean.
a tall, cone-shaped hill or mountain arising from the sea bottom with its summit beneath the surface of the sea, and often having a flat top, as a guyot does. [AHDOS
A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island. These are typically formed from extinct volcanos, that rise abruptly and are usually found rising from a seafloor of 1,000 4,000 metres depth. They are defined by oceanographers as independent features that rise to at least 1,000 metres above the seafloor.
