Are they not a plant life that will soak up CO and thus increase the O2 level in the ocean? Actually, if the phytoplankton fail to sink to the ocean then it can result in zooplankton blooms (krill) that consume the phytoplankton, and exhale CO2, which would acidify the waters near the surface. Which is why proponents prefer to fertilize areas where relatively heavy Diatoms proliferate when fertilized. An additional aspect of this is when ocean Salps, which come to the surface at night to feed on phytoplankton and then return to deeper water during the day, could be used to cull the blooms and drag their carbon load to the depths.

Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants. As more algae and plants grow, others die. This dead organic matter becomes food for bacteria that decomposes it. With more food available, the bacteria increase in number and use up the dissolved oxygen in the water. When the dissolved oxygen content decreases, many fish and aquatic insects cannot survive. This results in a dead area. en.wikipedia.org
