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.
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.
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 ...
A cyclonic eddy centered on 48 deg S, 16 deg E was selected for fertilization. The experiment began on India's Republic Day (26 January 2009). 10 tonnes (9.8 long tons; 11 short tons) of ferrous sulfate dissolved in seawater was spread over an area of 300 square kilometres (120 sq mi), and the patch created was monitored for 38 days to investigate the effects of iron addition on marine ...
With the help of vitro fertilization (IVF), we fulfilled our dream and brought two healthy children into the world. More than 8 million babies have been born this way since the first such birth in ...
The "five ways" proposed are geoengineering techniques: space lenses in orbit, to diffract sunlight away from the earth; cloud seeding with seawater to increase albedo; sulfur launched into the stratosphere to increase albedo; ocean fertilization with iron or urea (nitrogen fertilizer) artificial trees (see carbon capture and sequestration)
