Actually I had read the entire article, but the part you posted was even more bizarre in that it referred to decreasing ocean out gassing of CO2. I can only assume that what they did was measure a decrease in out gassing for a short period of time. That does not say much for actual sequestering. What needs to be shown is that you can take CO2 out of the air, not prevent more CO2 from entering. There appears to me to be another significant problem, which is that the plankton take dissolved CO2 in the ocean water, not CO2 from the surface atmosphere. Thus the uptake rate will be limited to the natural atmosphere/water absorption rate of CO2. It could be that rather than 1000's of tons in small areas, you need to seed much larger areas in steadystate conditions. It is one thing to rapidly delete existing dissolved CO2 in a given volume of water, but rather a different thing to be rate limited on the diffusion of CO2 from the atmosphere itself. The key will be testing on a size and time scale that allows them to actually show and measure sequestering. I hope somebody does it.
