Surface Ocean Fertilization
the absence of diatoms, a relatively small amount of carbon was sequestered, because other phytoplankton are vulnerable to predation by zooplankton and do not sink rapidly upon death. However, deep water the Use of Herbal Medications concentrations of dissolved CO2 could be returned to the atmosphere.

"Ocean fertilization: time to move on". Retrieved b Fountain, Henry. "Efficiency of carbon sequestration by added reactive nitrogen in ocean fertilisation". "The Global, Complex Phenomena of Harmful Algal Blooms Oceanography". 41 Side effects edit According to Gnadesikan and Marinou, 2008, Beyond biological impacts, evidences suggests that plankton blooms can affect the physical properties of surface waters simply by absorbing light and heat from the sun. Precautionary principle edit Main article: Precautionary principle The precautionary principle (PP) states that if an action or policy has a suspected risk of causing harm, in the absence of scientific consensus, the burden of proof that it is not harmful falls on those who would.

Ocean fertilization, untested geoengineering technique designed to increase the uptake of carbon dioxide (CO2) from the air by phytoplankton, microscopic plants that reside at or near the surface of the ocean.
