Muir Seamount

Muir Seamount is an underwater volcanic mountain in the North Atlantic Ocean. It rises from the seafloor but does not form an island above the sea surface.

Muir Seamount is a submarine volcano, but its catalog description does not by itself establish that it is currently active. Activity status should be checked against a modern seamount or marine geology database.

Its steep volcanic terrain creates hard surfaces and varied habitats in the deep ocean. Such seamount environments can support ecosystems that differ from the surrounding abyssal seafloor.

It is a seamount, meaning a volcanic mountain rising from the ocean floor. Unlike a guyot, a seamount is not defined by having a flat, eroded summit.
