    en.wikipedia.org/wiki/Seamount

    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.

    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, 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.

    en.wikipedia.org/wiki/Knoll_(oceanography)

    In marine geology, a knoll is defined as a rounded underwater hill, not exceeding 1000 meters in height. [1] Any rounded underwater features exceeding that height are referred to as seamounts. [2] They are believed to cover around 16.3% of the world's seafloor. [3]

    To give a scale of their mission, there are an estimated 100,000 seamounts in the ocean, but only 350 of them have been sampled, and only about 100 sampled thoroughly. [3] [5] Although sampling all 100,000 seamounts is infeasible, major seamounts can be sampled in such a way. [4] [6] [7] CenSeam is a subdivision of the Census of Marine Life ...

    en.wikipedia.org/wiki/Axial_Seamount

    The base of Axial Seamount is a long, low-lying plateau, and the eastern part of the seamount is defined by a series of linear scarps. Axial Seamount has two major volcanic rifts extending approximately 50 km (31 mi) north and south of its main summit, as well as several much smaller, ill-defined ones aligned in a roughly similar pattern.
