High-precision stable isotope geochemistry: Recovery of the geochemical memory of large-scale Earth system processes (e.g., microbial control of the global S cycle; anthropogenic manipulation of atmospheric OH abundances)
Earth system processes leave behind a geochemical 'memory' of their operation. In order to constrain the presence and vigor of these processes in the recent and ancient past, Professor Wing's research exploits the persistence of this memory in solid Earth archives and the unique ability of stable isotope measurements to recover it. Recent topics of study are varied and extend from the atmospheric trace gases that control the habitability of the planet to the deep crustal fluids involved in metamorphism and mountain building. Upcoming research will use high-precision measurements of total oxygen (16O, 17O, 18O) and sulfur (32S, 33S, 34S, 36S) stable isotope abundances to investigate microbial biogeochemistry under an anoxic Archean atmosphere, to constrain mass fluxes in the Phanerozoic geologic sulfur cycle, and to track processes that control the pollution-cleansing oxidants (OH, O3) in the modern atmosphere.
