Ocean fertilization by pyrogenic aerosol iron

Abstract Aerosols supply bioaccessible iron to marine biota which could affect climate through biogeochemical feedbacks. This paper review progresses in research on pyrogenic aerosol iron. Observations and laboratory experiments indicate that the iron solubility of pyrogenic aerosol can be considera...
