• It is a large system of ocean currents in the Atlantic Ocean, part of the global Thermohaline Circulation (also called the “Global Conveyor Belt”).
  • AMOC transports warm, salty surface water northward and cold, deep water southward.

How does it work?

  • Warm surface water flows from the tropics to the North Atlantic (e.g., Gulf Stream).
  • In the North Atlantic, the water cools and sinks due to increasing density (from cooling and salinity).
  • The cold, dense water flows southward at deep ocean levels.
  • Eventually, it upwells in the Southern Ocean and elsewhere, completing the circulation loop.
