Options for enhancing the storage of carbon dioxide in the oceans:A review
The various proposed options for enhancing CO2 storage are often ingenious but rarely feasible. Fertilizing the central gyres would require enormous amounts of N and P fertilizer. Addition of iron to the Southern Ocean has been rejected as inefficient. The deep sea disposal of 50–100% of fossil fuel...

The various proposed options for enhancing CO2 storage are often ingenious but rarely feasible. Fertilizing the central gyres would require enormous amounts of N and P fertilizer. Addition of iron to the Southern Ocean has been rejected as inefficient.

Ocean disposal applies only to point sources representing ~30% of fossil fuel emissions; relocation of these plants to maritime regions may not be economical either.
