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:
“What angels invented these splendid ornaments, these rich conveniences, this ocean of air above, this ocean of water beneath, this firmament of earth between? this zodiac of lights, this tent of dropping clouds, this striped coat of climates, this fourfold year?”
—Ralph Waldo Emerson (1803–1882)
“The point of the dragonfly’s terrible lip, the giant water bug, birdsong, or the beautiful dazzle and flash of sunlighted minnows, is not that it all fits together like clockwork--for it doesn’t ... but that it all flows so freely wild, like the creek, that it all surges in such a free, finged tangle. Freedom is the world’s water and weather, the world’s nourishment freely given, its soil and sap: and the creator loves pizzazz.”
—Annie Dillard (b. 1945)
