Editing Guyot (section)

==Characteristics==
The steepness gradient of most guyots is about 20 degrees.  To technically be considered a guyot or tablemount, they must stand at least {{convert|900|m|ft|abbr=on}} tall.<ref name="McGrawGuyot">{{Cite journal | url=http://www.accessscience.com/content/seamount-and-guyot/611100 | title=Seamount and guyot | journal=Access Science | access-date=2 February 2016| doi=10.1036/1097-8542.611100| url-access=subscription }}</ref>  One guyot in particular, the [[Great Meteor Seamount|Great Meteor Tablemount]] in the Northeast Atlantic Ocean, stands at more than {{convert|4000|m|ft|abbr=on}} high, with a diameter of {{convert|110|km|mi|abbr=on}}.<ref name="2aXWF">{{cite web|url=http://www.britannica.com/eb/topic-243463/Great-Meteor-Tablemount|title=Great Meteor Tablemount (volcanic mountain, Atlantic Ocean) – Britannica Online Encyclopedia<!-- Bot generated title -->|website=britannica.com|access-date=15 January 2019}}</ref>  However, there are many undersea mounts that can range from just less than {{convert|90|m|ft|abbr=on}} to around {{convert|900|m|ft|abbr=on}}.<ref name="McGrawGuyot" />  Very large oceanic volcanic constructions, hundreds of kilometres across, are called [[oceanic plateau]]s.<ref name="V63VR">{{cite web|url=http://www.answers.com/topic/seamount-and-guyot?cat=technology|title=Answers - The Most Trusted Place for Answering Life's Questions|website=Answers.com|access-date=15 January 2019}}</ref> Guyots have a mean area of {{convert|3,313|sqkm|sqmi|abbr=on}}, which is much larger than typical seamounts, which have a mean area of {{convert|790|sqkm|sqmi|abbr=on}}.<ref name="QsHHK">{{Cite journal | doi=10.1016/j.margeo.2014.01.011|title = Geomorphology of the oceans| journal=Marine Geology| volume=352| pages=4–24|year = 2014|last1 = Harris|first1 = P.T.| last2=Macmillan-Lawler| first2=M.| last3=Rupp| first3=J.| last4=Baker| first4=E.K.|bibcode = 2014MGeol.352....4H}}</ref>

There are 283 known guyots in the world's oceans, with the North Pacific having 119, the South Pacific 77, the South Atlantic 43, the [[Indian Ocean]] 28, the North Atlantic eight, the [[Southern Ocean]] six, and the [[Mediterranean Sea]] two; there are none known in the Arctic Ocean, though one is found along the [[Fram Strait]] off northeastern [[Greenland]].{{Citation needed|date=July 2022}} Guyots are also associated with specific lifeforms and varying amounts of [[organic matter]].  Local increases in [[chlorophyll a]], enhanced [[carbon]] incorporation rates and changes in [[phytoplankton]] [[species composition]] are associated with guyots and other [[seamount]]s.
