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:
“The frost was on the village roofs as white as ocean foam;
The good red fires were burning bright in every ‘longshore home;
The windows sparkled clear, and the chimneys volleyed out;
And I vow we sniffed the victuals as the vessel went about.”
—Robert Louis Stevenson (1850–1894)
“We can see that the baby is as much an instrument of nourishment for us as we are for him.”
—Polly Berrien Berends (20th century)
