John M. Edmond

John Marmion Edmond (born April 27, 1943 in Glasgow , † April 10, 2001 in Boston ) was a British-American geochemist and oceanographer .

Edmond studied at the University of Glasgow , where he graduated with a bachelor's degree in 1965. In 1970 he received his PhD from the University of California, San Diego and the Scripps Institute of Oceanography . He was a professor at the Massachusetts Institute of Technology .

He dealt with the quantitative analysis of processes in ocean chemistry. Using chemical water analysis from different parts of the world, he investigated what influences the transfer of chemical elements into and out of the oceans. For his research, he analyzed rare metals, trace elements and radioisotopes in water samples from black smokers in the deep sea (for example on the mid-ocean ridges or in the Gulf of California ) to the water of remote lakes and rivers in Tibet, Siberia, the Antarctic and the Arctic, the Lakes in the East African Rift and the rivers enriched by salt domes in the Andes . With this research, Edmund pioneered the element and isotope systematics for geochemical processes. He also contributed to paleoceanography and the reconstruction of the carbon dioxide cycle in the oceans in the earth's past.

In 1999 he received the Urey Award and he received the Macelwane Medal of the American Geophysical Union , of which he was a fellow. Edmond was a Fellow of the Royal Society .
