A method of sequestering carbon dioxide (CO2) in an ocean comprises testing an area of the surface of a deep open ocean in order to determine both the nutrients that are missing and the diffusion coefficient, applying to the area in a spiral pattern a first fertilizer that comprises a missing nutrient, and measuring the amount of carbon dioxide that has been sequestered. The fertilizer preferably comprises an iron chelate that prevents the iron from precipitating to any significant extent. The preferred chelates include lignin, and particularly lignin acid sulfonate. The method may further comprise applying additional fertilizers, and reporting the amount of carbon dioxide sequestered. The method preferably includes applying a fertilizer in pulses. Each fertilizer releases each nutrient over time in the photic zone and in a form that does not precipitate.
