Webb9 aug. 2024 · The AMOC is a large system of ocean currents. It is the Atlantic branch of the ocean conveyor belt or Thermohaline circulation (THC), and distributes heat and nutrients throughout the world’s ocean basins. AMOC carries warm surface waters from the tropics towards the Northern Hemisphere, where it cools and sinks.
