Life

Canfield earned a Bachelor of Science degree in chemistry from Miami University in 1979 . He then studied at Yale University , where he received a Master of Philosophy (1984) and Ph.D. (1988) in geochemistry . Since 1982 he has held various positions as a research assistant at Yale University before he worked for NASA from 1988 to 1991 . During this time I also went abroad to Denmark . From January 1992 to May 1995, Canfield was an Assistant Professor at the Georgia Institute of Technology .

Canfield Ocean

Oxygen content over the history of the earth

According to Canfield, the band ores of the Precambrian were not formed by oxidation ( Great Oxygen Disaster ), but by reaction with sulfides . The Canfield Ocean was an anoxic ocean that existed between the Archean and Ediacarian and led to mass extinction .
