Douglas Rumble III

Douglas Rumble III uses the stable isotopes of oxygen and sulfur to explore the evolution of Earth's atmosphere by analyzing ancient rocks and to understand the origin of the Solar System through study of meteorites. He obtained a Ph.D in geological sciences from Harvard University in 1969, and a BA in geology from Columbia University in 1964.

He has been a staff scientist in petrology and geochemistry at the Geophysical Laboratory since 1973. He served as a program director in the Division of Earth Sciences, National Science Foundation, 1985 to 1987. He is a past-President of both the Geological Society of Washington and the Mineralogical Society of America. He is a Fellow of the Geochemical Society, the Geological Society of America, and the Mineralogical Society of America.

Rumble’s current research is centered on the three stable isotopes of oxygen and the four stable isotopes of sulfur. Oxygen isotopes are used to distinguish processes that occurred in the solar nebula from those taking place in planetary bodies after their condensation from the nebula. On Earth, the anomalous fractionation of oxygen isotopes during the formation of ozone from oxygen by ultraviolet photolysis leaves an indelible record of atmospheric chemistry. The four stable isotopes of sulfur provide insights into the evolution of Earth’s atmosphere in the form of anomalous fractionations recorded in sulfur-bearing minerals from rocks as old as 3.8 billion years.
