The Role of Ocean Eddies in Redistributing Heat and Nutrients
Quick fact
Some ocean eddies are so large they can be seen from space, and they can transport heat equivalent to the power output of millions of power plants, influencing weather patterns thousands of kilometers away.
Why this is interesting
You've seen the ocean's surface — calm or stormy — but hidden below are giant swirling 'storms' of water that help regulate our climate. What if these spiraling currents are the ocean's own conveyor belts for heat and life?
