<p>A method of sequestering carbon dioxide (CO 2 ) in an ocean comprising 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 a first fertilizer that comprises a missing nutrient, and measuring the amount of carbon dioxide that has been sequestered. The application of the first fertilizer is preferably in a spiral pattern which results in a patch of fertilizer. The concentration of the fertilizer preferably does not vary by more than about 50% within about two days of the local application. The concentration of the fertilizer at the center of the patch preferably does not decrease through diffusion by more than about 5% during a time period of about 20 days after the application of the patch of fertilizer. The method may further comprise applying additional fertilizers, and reporting the amount of carbon dioxide sequestered. The method preferably limits zooplankton and fish growth by applying each fertilizer in pulses. Each fertilizer releases each nutrient over time in the photic zone and in a form that does not precipitate.</p> |
