Our oceans move vast amounts of water, heat, chemicals and microscopic life around the planet - with one ocean current particularity crucial to life on earth.

The Atlantic Meridional Overturning Circulation, or AMOC, is vital in regulating the temperature of the earth.

Scientists measure it using scientific instruments deployed in different latitudes across the north and south Atlantic Ocean.

But studies have suggested it will slow down or even collapse, which could have a catastrophic effect on our climate, and lead to more extreme weather.
