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:
“Oh, a capital ship for an ocean trip,
Was the Walloping Window Blind;
No gale that blew dismayed her crew
Or troubled the captain’s mind.”
—Charles Edward Carryl (1841–1920)
“While you are nurturing your newborn, you need someone to nurture you, whether it is with healthful drinks while you’re nursing, or with words of recognition and encouragement as you talk about your feelings. In this state of continual giving to your infant—whether it is nourishment or care or love—you are easily drained, and you need to be replenished from sources outside yourself so that you will have reserves to draw from.”
—Sally Placksin (20th century)
