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.

Deployment of new pressure sensors at 26ºN

Two new sensors have been deployed at 26°N in the Atlantic to measure ocean bottom pressure. Ocean pressure has been measured for decades, but typically suffers from ‘drift’ in the measurement – meaning that the measured value becomes more inaccurate over time.
