Manning Guyot

Manning Guyot is a flat-topped seamount in the Pacific Ocean. A guyot is an underwater volcanic mountain whose summit has been worn or otherwise flattened below sea level.

Its flat summit is linked to an ancient shallow-water or near-sea-level stage, when erosion and coral growth shaped the top before the seamount subsided. It is now deep beneath the Pacific surface.

The rocky seamount provides habitat for deep-sea marine life. Its hard surfaces create places for organisms to attach and for communities to gather in an otherwise soft-sediment ocean environment.

The seamount was named after oceanographic surveying vessels. Its name identifies a mapped Pacific seafloor feature rather than an island above the water.
