Great Meteor Seamount
|Great Meteor Seamount|
Great Meteor Seamount at the southern edge of the Atlantis-Meteor Seamount Complex
|Summit depth||270 m|
|Location||North Atlantic Ocean, 1000 km south of the Azores|
|Volcanic arc/chain||Seewarte Seamounts|
The Great Meteor Seamount is a large guyot (tablemount) located south of the Azores in the Atlantic Ocean. It is the New England hotspot's most recent eruptive center and is one of the most completely investigated seamounts in the world. This guyot rises up from a depth of almost 4,800 meters to about 270 meters below the surface of the Atlantic. The summit measures 50 km x 28 km (1465 km²). On the southwest side it is flanked by the smaller Little Meteor Seamount and the still smaller Closs Seamount.
The New England hotspot formed the White Mountains 124 to 100 million years ago when the North American continent was directly overhead. As the continent drifted to the west, the hotspot gradually moved offshore. On a southeasterly course, the hotspot formed Bear Seamount, the oldest in the chain, about 100 to 103 million years ago. Over the course of millions of years, it continued creating the rest of the seamounts, eventually culminating in the Nashville Seamount about 83 million years ago. As the Atlantic Ocean continued to spread, the hotspot eventually "traveled" further east, forming the Great Meteor Seamount where it is found today.
