WThe New England Seamounts is a chain of over twenty underwater extinct volcanic mountains known as seamounts. This chain is located off the coast of Massachusetts in the Atlantic Ocean and extends over 1,000 km from the edge of Georges Bank. Many of the peaks of these mountains rise over 4,000 m from the seabed. The New England Seamounts chain is the longest such chain in the North Atlantic and is home to a diverse range of deep sea fauna. Scientists have visited the chain on various occasions to survey the geologic makeup and biota of the region. The chain may be part of the Great Meteor hotspot track and was formed either by the movement of the North American Plate over the New England hotspot or passive melting due to lithospheric extension caused by tectonic changes in the Atlantic Ocean. The oldest volcanic activity that has been connected with the seamounts are kimberlites at Rankin Inlet just northwest of Hudson Bay in Canada, though their forming part of a hotspot track is disputed. Part of the seamount chain is protected by Northeast Canyons and Seamounts Marine National Monument.
WAmerican Scout Seamount appeared on charts of the North Atlantic Ocean published during the 1950s. It was located near 46°30′N 37°30′W with a depth of 37 meters. Investigations by the Woods Hole Oceanographic Institution research vessel Atlantis II in 1964 found no evidence that it existed.

WThe Corner Rise Seamounts are a chain of extinct submarine volcanoes in the northern Atlantic Ocean east of the New England Seamounts. The origin of the chain is disputed. According to one view, it formed as the North American Plate moved over the Great Meteor hotspot between 80 to 76 Ma. Another view is it arose from shallow melting due to reactivation of pre-existing zones of lithospheric weakness caused by intraplate stresses related to tectonic changes in the Atlantic Ocean. The chain constitutes the shallowest seamounts off New England, with some of its nineteen highest peaks only 800–900 m deep.
WThe Bear Seamount is a guyot or flat-topped underwater volcano in the Atlantic Ocean. It is the oldest of the New England Seamounts, which was active more than 100 million years ago. It was formed when the North American Plate moved over the New England hotspot. It is located inside the Northeast Canyons and Seamounts Marine National Monument, which was proclaimed by President of the United States Barack Obama to protect the seamount's biodiversity.

WCadamosto Seamount is a seamount in the Cape Verde islands, 25 kilometres (16 mi) southwest of Brava. It rises to a depth of 1,380 metres (4,530 ft) and partially overlaps with Brava. The seamount appears to be one of the recently active volcanic centres of the Cape Verde islands and has produced phonolite. The seamount has had intense volcanic eruptions in the late Pleistocene, and recent seismic activity indicates that volcanism is ongoing.
WThe Caloosahatchee Seamount is a seamount in the northern Atlantic Ocean. It is part of the Corner Rise Seamounts, which was active about 75 million years ago.

It formed through volcanism during the early Cenozoic in the Rockall Trough 60 million to 67 million years ago and afterwards sank below sea level. Presently, it is a flat-topped underwater mountain that rises to about 980 metres depth. "Coral gardens" that host a number of animals are found on its slopes.
WHenry Seamount is a seamount of Cretaceous age southeast of El Hierro in the Canary Islands. It is 660 metres (2,170 ft) high above the seafloor and covered with sediments. Despite its old age, it shows evidence of recent eruptions and of hydrothermal activity in the last 3,350 years. This activity may be either mediated by groundwater flow from El Hierro or by recent eruptions of Henry Seamount.

WTagoro is an submarine volcano located off the southern coast of the island of El Hierro, in the Atlantic Ocean. It is part of the Canary Islands Seamount Province.
WTropic Seamount is a Cretaceous seamount southwest of the Canary Islands, north of Cape Verde and west of the Western Sahara, one of a number of seamounts in this part of the Atlantic Ocean. It was probably formed by volcanic processes triggered by the proximity to the African continent. Tropic Seamount is located at a depth of 970 metres (3,180 ft) and has a summit platform with an area of 120 square kilometres (46 sq mi).
WVema Seamount is a seamount in the South Atlantic Ocean. Discovered in 1959 by a ship with the same name, it lies 1,600 kilometres (1,000 mi) from Tristan da Cunha and 1,000 kilometres (620 mi) northwest of Cape Town. The seamount has a flat top at a mean depth of 73 metres which was eroded into the seamount at a time when sea levels were lower; the shallowest point lies at 26 metres depth. The seamount was formed between 15-11 million years ago, possibly by a hotspot.
WVesteris Seamount, also known as Vesteris Bank, is a seamount in the Greenland Sea of the North Atlantic Ocean between Greenland and Norway. It lies north of Jan Mayen and rises from 41–43 million years old ocean crust. The reasons for the volcanic activity at Vesteris are unclear and may involve lithospheric processes.
WThe New England Seamounts is a chain of over twenty underwater extinct volcanic mountains known as seamounts. This chain is located off the coast of Massachusetts in the Atlantic Ocean and extends over 1,000 km from the edge of Georges Bank. Many of the peaks of these mountains rise over 4,000 m from the seabed. The New England Seamounts chain is the longest such chain in the North Atlantic and is home to a diverse range of deep sea fauna. Scientists have visited the chain on various occasions to survey the geologic makeup and biota of the region. The chain may be part of the Great Meteor hotspot track and was formed either by the movement of the North American Plate over the New England hotspot or passive melting due to lithospheric extension caused by tectonic changes in the Atlantic Ocean. The oldest volcanic activity that has been connected with the seamounts are kimberlites at Rankin Inlet just northwest of Hudson Bay in Canada, though their forming part of a hotspot track is disputed. Part of the seamount chain is protected by Northeast Canyons and Seamounts Marine National Monument.
