Laboratory scope
The laboratory applies stable and rare isotopes to biogeochemical questions spanning atmospheric oxidation, global carbon cycling, environmental geochemistry, hydrology, paleoclimate, and planetary atmospheres.
A central direction uses the triple oxygen isotopic composition of atmospheric CO₂ as an independent constraint on carbon-cycle processes. Related work examines ozone-mediated oxidation, particulate pollution, geological archives, water–rock interaction, hydrological microphysics, and planetary photochemistry.
