From Wikipedia - Reading time: 4 min
John Holland Martin (February 27, 1935 – June 18, 1993), was an American oceanographer, known for his research work at the Moss Landing Marine Laboratories.
Life and career
[edit]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. He is also known for the Martin curve, a power law which is widely used by oceanographers to describe the export to the ocean floor of particulate organic carbon (POC).[2]
John Martin died from prostate cancer at the age of 58.
Quotes
