    • found: Seamounts--hotspots of marine life, via International Council for the Exploration of the Sea website, May 23, 2005(Seamounts are undersea mountains (usually of volcanic origin) rising from the seafloor and peaking below sea level. Underwater mountains of heights above 1000 m are considered to be seamounts, those between 500-1000 m as knolls, and those below 500 m as hills. A seamount tall enough to break the sea surface is called an oceanic island, e.g., the islands of Hawaii, the Azores and Bermuda were all underwater seamounts at some point in the past.)

A seamount having a comparatively smooth flat top. Also called tablemount. See also Seamount.)
    • found: Glossary of geology, 1997(seamount: An elevation of the sea floor, 1000 m or higher, either flat-topped (called a guyot) or peaked (called a seapeak). Seamounts may be either discrete, arranged in a linear or random grouping, or connected at their bases and aligned along a ridge or rise.)
