The global meridional overturning circulation (GMOC), also known as the ocean conveyor belt, is a large-scale ocean circulation system that connects the Arctic, Atlantic, Indian, and Pacific Oceans via the Southern Ocean.[1]

Abyssal ocean circulation

The abyssal ocean circulation is a key component of the global meridional overturning circulation, cycling heat, carbon, oxygen and nutrients throughout the world ocean. Though melting of ice around Antarctica is projected to cause a rapid slowdown of the major global deep ocean current by 2050 - subsequent could alter the world’s climate for centuries and accelerate sea level rise.[2]
