Ocean mining for nutrient rich waters.....

Ocean pumps could counter global warming - environment - 26 September 2007 - New Scientist

The idea is to tether millions of vertical pipes across the oceans to pump nutrient-rich deep water to the surface. These waters would fertilise the growth of algae, which in turn fix carbon dioxide. The pipes, reaching to depths of 200 metres, would have flap valves at the bottom operated by the energy of waves, which would push deep water up the pipe.

And another good one.
HowStuffWorks "Why do some scientists want to scatter tubes throughout the open ocean?"

The vertical tubes wouldn't require any outside energy input, and would instead rely on the natural energy of wave motion to force water up their 656-foot (200-meter) length. A flap or valve at the bottom of each tube would keep the flow of water one-way. The idea is to place the tubes, which would probably be between 10 and 33 feet (3 and 10 meters) wide, approximately 1.2 miles (2 kilometers) apart and secure them using underwater tethers and surface buoys.

I think I saw that episode. Didn't the tube collapse before they could see if it did any good?
