Born in Old Lyme, Connecticut, he is known for his research on the role of iron as a phytoplankton micronutrient, and its significance for so-called "High-Nutrient, Low Chlorophyll" regions of the oceans. [1] He further advocated the use of iron fertilization to enhance oceanic primary production and act as a sink for fossil fuel carbon dioxide.
In 1988, John Martin confirmed the hypothesis that iron limits phytoplankton blooms and growth rates in the North Pacific. His work was extrapolated to other HNLC regions through evidence which linked low surface iron concentration with low chlorophyll. [6]
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.
The Vertical Transport and Exchange of Ocean Particulate program (VERTEX) was initiated by Moss Landing Marine Labs in 1981 by Dr. John Martin. [4] This project resulted in the development of the Iron Iron fertilization theory (then known as the Iron Hypothesis) which stated iron was a limiting factor in ocean water phytoplankton production and ...
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.
120 tons of iron compound were deposited in the migration routes of pink and sockeye salmon in the Pacific ocean West of Haida Gwaii over a period of 30 days. [1] The project resulted in a 35,000 km 2 (14,000 sq mi) plankton bloom that lasted for several months and was confirmed by NASA satellite imagery. [ 2 ]

In the summer of 2012, an iron fertilization experiment deposited 100 tons of finely-ground iron oxides into a Haida eddy in an effort to increase salmon returns through an attempt to increase primary production. This resulted in the highest chlorophyll concentrations measured within an eddy, and the most intense phytoplankton bloom in the last ...
