What is the AMOC?

The AMOC or Atlantic Meridional Overturning Circulation is a large-scale circulation pattern in the ocean. It is responsible for northward transport of heat equivalent to 1 million power plants.

AMOC variability and climate

Fluctuations in the AMOC are responsible for changing the distribution of heat, carbon and other properties within the ocean, with knock-on effects for atmospheric circulation and climate.

Observing the AMOC

The AMOC was traditionally observed using hydrographic sections from ships. One expedition lasted up to 6 weeks and produced a single estimate. Now we use moored observations to make continuous observations.
