Ocean fertilization or ocean nourishment is a type of geoengineering based on the purposeful introduction of nutrients to the upper ocean to increase marine food production and to remove carbon dioxide from the atmosphere. A number of techniques, including fertilization by iron, urea and phosphorus have been proposed. Another possible objective of ocean fertilization is to produce more sulfate aerosol in the atmosphere and so increase the amount of sunlight being reflected by clouds, cooling the Earth. There has been commercial interest in using these techniques to reduce carbon dioxide concentrations.

Famous quotes containing the words ocean and/or nourishment:
“your old fashioned tirade—
loving, rapid, merciless—
breaks like the Atlantic Ocean on my head.”
—Robert Lowell (1917–1977)
“Our ancestors were savages. The story of Romulus and Remus being suckled by a wolf is not a meaningless fable. The founders of every state which has risen to eminence have drawn their nourishment and vigor from a similar wild source. It was because the children of the Empire were not suckled by the wolf that they were conquered and displaced by the children of the northern forests who were.”
—Henry David Thoreau (1817–1862)
