description Great Meteor Guyot Overview
Rising from the floor of the northeast Atlantic south of the Azores, Great Meteor Guyot is a volcanic seamount with a broad, flattened summit. The term guyot, also called a tablemount, describes this flat-topped form. Its geological record includes Miocene-age deposits, although the formation's history cannot be reduced to a single period. It belongs to the southern Azores seamount chain rather than the Canary region.
Its large underwater platform makes it an important subject for marine geology and oceanography. Research examines how the seamount formed and how its shape affects surrounding water movement and marine habitats. As one of the Atlantic's large seamounts, it provides a useful setting for studying connections between volcanic structures and ocean processes. Its main relevance is scientific, particularly for work on volcanism and the physical environment of the deep ocean.
help Great Meteor Guyot FAQ
Where is the Great Meteor Guyot located in the ocean?
The Great Meteor Guyot is located in the North Atlantic Ocean, south of the Azores islands and the Canary region. It sits isolated on the ocean floor, completely submerged beneath thousands of feet of water.
How large is the Great Meteor Guyot?
It is one of the largest single seamounts in the entire Atlantic Ocean, featuring a massive base diameter of over 100 kilometers. Its flat summit plateau alone covers an area of roughly 1,500 square kilometers.
How did the Great Meteor Guyot get its flat top?
The guyot was originally an active volcano that built up above the ocean surface during the Miocene era. Over millions of years, the top of the volcano was eroded flat by wave action and weathering before the sea floor cooled and sank it back underwater.
Can scientists study the Great Meteor Guyot directly?
Because it lies roughly 3,000 meters below the ocean surface, scientists cannot study it directly without submersibles. Instead, oceanographers rely heavily on deep-sea dredging, seismic profiling, and remotely operated vehicles (ROVs) to analyze its geological makeup.
