Central Atlantic Ocean floor

E95729

ocean floor region submarine physiographic province

The Central Atlantic Ocean floor is a vast underwater region characterized by mid-ocean ridges, fracture zones, and sediment-covered abyssal plains formed by seafloor spreading between the Americas and Africa-Europe.

How this entity was disambiguated

This entity first appeared as the object of triple T798670 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Central Atlantic Ocean floor
Context triple: [African Plate, includesRegion, Central Atlantic Ocean floor]

A. North Atlantic area
The North Atlantic area is the broad transatlantic region encompassing the northern parts of the Atlantic Ocean and surrounding countries in Europe and North America that form the geographic focus of NATO’s collective security.
B. South Atlantic mid-ocean ridge system
The South Atlantic mid-ocean ridge system is a major underwater mountain chain where tectonic plates diverge in the South Atlantic Ocean, creating new oceanic crust and hosting features such as the Bouvet Triple Junction.
C. North Atlantic Deep Water
North Atlantic Deep Water is a cold, dense water mass formed in the high-latitude North Atlantic that sinks and flows southward, driving a major component of the global ocean circulation and climate system.
D. Northern Pacific Ocean
The Northern Pacific Ocean is the northernmost part of the Pacific Ocean, encompassing vast subarctic and temperate waters that include marginal seas such as the Bering Sea and support rich marine ecosystems and major shipping routes.
E. South Atlantic subtropical gyre
The South Atlantic subtropical gyre is a large, clockwise-rotating system of ocean currents in the South Atlantic Ocean that plays a key role in global heat transport and climate regulation.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
