Patton Seamount
Patton Seamount is a prominent seamount (underwater volcano) in the Cobb-Eickelberg Seamount chain in the Gulf of Alaska. Located east of Kodiak Island and reaching to within of the ocean surface, Patton is one of the largest seamounts in the Cobb-Eickelberg Seamount chain. It was originally created near the coast of Oregon by the Cobb hotspot 33 million years ago, and was moved to its present location by tectonic plate movement. Patton is one of the most well-understood seamounts, as a major expedition using ''DSV Alvin'' in 1999 and another in 2002 helped define the scope of the seamount's biological community. Like other large seamounts, Patton acts as an ecological hub for sea life. Dives have revealed that the volcano is heavily encrusted in sea life of various forms, including sea stars, corals, king crabs, demersal rockfish, and other species.
== Geology ==
Patton Seamount was created by the Cobb hotspot, and it lies in the Cobb-Eickelberg Seamount chain. The Cobb chain is unusual in that it is not one individual volcanic chain, but a mosaic of many, created by several hotspots that now lie along the western coast of North America. Patton Seamount lies near the northwestern edge of the chain, in the Gulf of Alaska, and is 33 million years of age, among the oldest in the group. The part of the chain that Patton Seamount lies in is known variably as either the "Gulf of Alaska Seamounts" or the "Patton Seamounts." The Gulf seamounts are the best-known and most heavily studied features in the chain.
Patton itself is over tall and wide at is base, and originally formed off the coast of Washington 33 million years ago. It has since been moved to its present Gulf location by the northwestern movement of the Pacific Plate.〔(【引用サイトリンク】url=http://www.mcbi.org/shining_sea/place_npacifc_gulf.htm )〕 Dives indicate that the structure of Patton Seamount is rough near the top, with many boulders, and consists of much broader, finer particulates near the ocean bottom.〔 Not much is known about Patton geologically, as expeditions have mostly focused on its biology.
