Anton Dohrn Seamount
The Anton Dohrn Seamount is a guyot in the Rockall Trough in the northeast Atlantic. It is high and is topped with pinnacles, one of which reaches a depth of . Away from the flat top upon which the pinnacles rest, the slopes fall off steeply into the Rockall Trough and a moat in the sediment that surrounds the seamount. It appears to be a volcano formed by basaltic lava and tuff. It formed during the Cretaceous and Paleogene and was proposed to be a source for bentonite layers across the British Isles. After the Cretaceous, subsidence and erosion lowered its top until it sank below sea level. The seamount was discovered in 1958. Anton Dohrn Seamount hosts a diverse ecosystem characterized by reefs formed by cold water corals, sponges and xenophyophorans, which themselves host a number of animals. It has been affected by human fishing operations, however. Name and research history Anton Dohrn Seamount is also known as Anton Dohrn Kuppe, a name used by German charts, and ...

North Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
