Fieberling Tablemount

Fieberling Tablemount is a flat-topped submarine volcano, also called a guyot, in the Pacific Ocean. Its level summit records erosion or wave planation when the volcano was closer to sea level before it subsided beneath the ocean.

A guyot typically forms when an island volcano grows above sea level, is worn down to a relatively flat surface, and later sinks as the oceanic crust cools and subsides. The flat top is therefore evidence of a different geological history from a sharp volcanic peak.

It is generally discussed as an extinct or inactive submarine volcanic feature rather than a currently erupting volcano. Its importance is geological and ecological, because seamounts create hard surfaces and varied habitats in the deep ocean.

Seamounts can concentrate currents and provide surfaces for corals, sponges, fish, and other marine organisms. The exact community around Fieberling Tablemount depends on depth, water flow, and local conditions, so it should not be treated as a shallow-water reef.
