VITA
Kenneth A. McGee graduated from the University of Missouri in 1970 and 1973
with degrees in Geology and an emphasis on low temperature aqueous geochemistry.
He joined the staff of the Experimental Geochemistry and Mineralogy Branch of
the USGS in Washington, D.C. in 1972. His early work with the USGS included
research on brucite solubility, silicic acid complexing, the solubility of
methane in sodium chloride brines, and the aqueous transport of iron and
uranium. In the late 1970's, he joined a project focused on volcanic gas
emissions. This led to research projects in Hawaii, Iceland, Long Valley, and
Mount St. Helens utilizing electrochemical sensors for measuring volcanic
degassing. In 1984 he moved to the Cascades Volcano Observatory where he served
as Deputy Scientist-in-Charge for five years. In 1989 he went back into
research involving magmatic volatiles. His current work involves research into
the relationships between gas emissions from volcanoes and the processes
operating in volcanic terrains using data from intermittent fumarole sampling,
continuous in-situ geochemical monitoring, and airborne plume measurements. He
is also interested in volcanic exhalations to the atmosphere and the impact on
Earth's climate. He is a member of the American Geophysical Union.
