BOWIE SEAMOUNT




Bowie Seamount is a large submarine volcano in the northeastern Pacific Ocean, located 180 km (110 mi) west of Haida Gwaii, British Columbia, Canada.
The seamount is named after William Bowie of the Coast & Geodetic Survey.


The volcano has a flat-topped summit (thus making it a guyot) rising about 3,000 m (10,000 ft) above the seabed, to 24 m (79 ft) below sea level. The seamount 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.
