An Oceanic Problem: the Atlantic Overturning Current is ...
Diagrams of the Global Conveyor Belt (GCB) are two dimensional and therefore simplified and do not, for example, include all of the intermediate water masses or surface water currents. However, the key of the Global Conveyor Belt concept is that it explains the general systems of heat transport as well as bottom water aging and nutrient supply in the oceans.

Why the Atlantic Ocean's 'conveyor belt' is key to global ...
Global warming could, via a shutdown of the thermohaline circulation, trigger cooling in the North Atlantic, Europe, and North America. This would particularly affect areas such as the British Isles, France and the Nordic countries, which are warmed by the North Atlantic drift. Major consequences, apart from regional cooling, could also include an increase in major floods and storms, a ...

Atlantic 'conveyor belt' not slowing, NASA study finds ...
This circulation is sometimes compared to a conveyor belt that pulls warm surface sea water north via the Atlantic, because sea is needed to replace the sea that has sunk. The global capacity of this system is thought to be about 16-20 Sv, where Sv is a unit of ocean current flow, 1 Sv = 1 million m 3 /s (million cubic metres per second).

A global conveyor belt This Atlantic current is also called the Atlantic Meridional Overturning Circulation, or AMOC. It works like a colossal conveyor belt. It carries warm water along the Atlantic Ocean surface, moving from south to north. Near Greenland, the current makes a U-turn. Then the cold water sinks and flows south again.

The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These two regions don't mix except in certain special areas. The ocean currents, the movement of the ocean in the surface layer, are driven mostly by the wind. In certain areas near the polar oceans, the colder surface water also gets saltier due to evaporation or sea ice formation.

The Atlantic conveyor is a vast ocean current with 16 times more volume than all of the rivers of the earth combined. In the map below you can see that it is part of a global ocean circulation. Both the Atlantic Conveyor (light and dark blue arrows) and the Gulf Stream (red and green arrows) carry warm tropical waters to the north.

The surface ocean current brings new water to this region from the South Atlantic via the Gulf Stream and the water returns to the South Atlantic via the North Atlantic Deep Water current. The continual influx of warm water into the North Atlantic polar ocean keeps the regions around Iceland and southern Greenland mostly free of sea ice year round.

The current travels around the edge of Antarctica, where the water cools and sinks again, as it does in the North Atlantic. Thus, the conveyor belt gets "recharged." As it moves around Antarctica, two sections split off the conveyor and turn northward. One section moves into the Indian Ocean, the other into the Pacific Ocean.
