Ocean fertilization or ocean nourishment is a type of technology for carbon dioxide removal from the ocean based on the purposeful introduction of plant nutrients to the upper ocean to increase marine food production and to remove carbon dioxide from the atmosphere.
Ocean iron fertilization is an example of a geoengineering technique that involves intentional introduction of iron-rich deposits into oceans, and is aimed to enhance biological productivity of organisms in ocean waters in order to increase carbon dioxide (CO 2) uptake from the atmosphere, possibly resulting in mitigating its global warming effects.
Since past iron fertilization experiments have resulted in large phytoplankton blooms, some have suggested that large-scale ocean fertilization experiments should be conducted to draw down inorganic anthropogenic carbon dioxide in the form of particulate organic carbon. Fertilization would stimulate biological productivity, leading to a ...
LOHAFEX was an ocean iron fertilization experiment jointly planned by the Council of Scientific and Industrial Research (CSIR) in India and the Helmholtz Association in Germany. The purpose of the experiment was to see if the iron would cause an algal bloom and trap carbon dioxide from the atmosphere.

Iron fertilization is the intentional introduction of iron-containing compounds (like iron sulfate) to iron-poor areas of the ocean surface to stimulate phytoplankton production. This is intended to enhance biological productivity and/or accelerate carbon dioxide (CO 2 ) sequestration from the atmosphere.
Full article: Iron Fertilization. Iron fertilization is a facet of geoengineering, which purposefully manipulates the Earth's climate system, typically in aspects of the carbon cycle or radiative forcing. Of current geoengineering interest is the possibility of accelerating the biological pump to increase export of carbon from the surface ocean.
Born in Old Lyme, Connecticut, he is known for his research on the role of iron as a phytoplankton micronutrient, and its significance for so-called "High-Nutrient, Low Chlorophyll" regions of the oceans. [1] He further advocated the use of iron fertilization to enhance oceanic primary production and act as a sink for fossil fuel carbon dioxide.
