What is a Seamount?

Fact Sheet. Seamounts rise high off the seafloor, much like mountains do on land, though most are remnants of extinct volcanoes. To be classified as a seamount, the feature must rise at least 1,000 meters (3,300 feet) above the surrounding seafloor. Satellite data indicate seamounts are located throughout every ocean basin, yet the majority remain unexplored. Use this resources to help students learn about the morphology, distribution, and importance of exploring seamounts. Download the PDF for the full version of this Fact Sheet.
