The Seamounts Portal

Denson Seamount
A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island. These are typically formed from extinct volcanoes, that rise abruptly and are usually found rising from a seafloor of 1,000–4,000 meters depth. They are defined by oceanographers as independent features that rise to at least 1,000 meters above the seafloor. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. An estimated 30,000 seamounts occur across the globe, with only a few having been studied. However, some seamounts are also unusual. For example, while the summits of seamounts are normally hundreds of meters below sea level, the Bowie Seamount rises from a depth of about 3,000 meters to within 24 meters of the sea surface.

About this project

You can help!

WikiProject Seamounts

We are a small (tiny!) WikiProject dedicated to improving Wikipedia's coverage of Seamount sand other underwater volcanic anomities- and we need your help! There are lots of articles in our criterea in need of expansion or creation. You can help by joining! You can also help us sort out all of the Seamount pics on Commons here and here. We work on:

  • All articles about seamounts, mid-ocean ridges, and other oceanic mountain structures.
  • Also articles about many types of seamounts (guyots, submarine volcanoes, submerged continental fragments) are within the scope.
  • Articles about some oceanic species are included within the project's scope because of their association with seamounts.
  • Articles about some marine protected areas which have been set aside primarily because of their seamounts.
  • Articles about people, places, or other entities notable for their association with a seamount.

Please feel free to join the project and expand its scope in any necessary directions.

Bowie Seamount
Bowie Seamount map.jpg

Bowie Seamount is a large submarine volcano in the northeastern Pacific Ocean, located 180 km (112 mi) west of the Queen Charlotte Islands, British Columbia, Canada. The volcano has a flat-topped summit (thus making it a guyot) rising about 3,000 m (9,843 ft) above the seabed, to 24 m (79 ft) below sea level. It lies at the southern end of a long underwater volcanic mountain range called the Pratt-Welker or Kodiak-Bowie Seamount chain, stretching from the Aleutian Trench in the north almost to the Queen Charlotte Islands in the south.

Bowie Seamount lies on the Pacific Plate, a large segment of the Earth's surface which moves in a northwestern direction under the Pacific Ocean. Its northern and eastern flanks are surrounded by neighboring submarine volcanoes; Hodgkins Seamount on its northern flank and Graham Seamount on its eastern flank.

To do

Tasks clipboard

Assess articles in scope of the project.

  • Add seamount categories to articles.
  • Add {{Infobox Seamount}}, {{WikiProject Seamounts}}, and other seamount-related fields to pages within our scope.
  • Expand seamount articles which are stubs, esp. by adding photos and references.
