John M. Edmond

John Marmion Edmond FRS (April 27, 1943 – April 10, 2001) was a professor of marine geochemistry and oceanography at the Massachusetts Institute of Technology, who did pioneering work on oceanic particulate matter, the oceanic carbon dioxide cycle, trace elements, and radioisotopes. He explored and analyzed water chemistry from environments as diverse as the mid-ocean ridge hydrothermal vents to the polar oceans to remote rivers and lakes in South America, Africa, Siberia, and Tibet. He and his students and colleagues in his lab measured more chemical elements at lower concentrations in water than had ever been done before. Provided by Wikipedia
