[vc_row][vc_column][vc_column_text]Guyots –   Guyots (pronounced “Ghe Oh’s”) are “an isolated (or group of) seamount (s) having a comparatively smooth flat top. Also called tablemount(s)” (IHO, 2008).  Harris et al. (2014) mapped 283 guyots covering a total area of 707,600 km2.  Guyots have an average area of 2,500 km2, more than twice the average area of seamounts.  Nearly 50% of guyot area and 42% of the number of guyots occur in the North Pacific Ocean, covering 342,070 km2 (see Table).  The largest three guyots are all in the North Pacific: the Kuko Guyot (estimated 24,600 km2), Suiko Guyot (estimated 20,220 km2) and the Pallada Guyot (estimated 13,680 km2).
