I too would be interested to see a cost and environmental analysis of the benefits and drawbacks of this kind of set up. I imagine that using carbon dioxide available in the ocean would be more energy (and perhaps cost) efficient than CO2 treatment in a greenhouse. But I also imagine that there would be substantial costs (and carbon expenditures) related to maintenance and harvesting of these plots. I wonder if those two balance out?
I would also be concerned about the environmental impact on the sea floor ecosystem.
