Our research projects are primarily focused on the application of stable isotopes to the study of paleoenvironments and the evolution of the earth system.

Greendland ice corePrincipal Investigator Eric Steig - We use water isotope (δD, δ18O, and Δ17O) data from ice cores to document past climate changes.

Greendland geology sample collectionPrincipal Investigator Becky Alexander - We measure changes in atmospheric chemistry using oxygen isotope (Δ17O) data from reactive nitrogen and sulfur compounds.

Greendland geology sample collectionPrincipal Investigator Roger Buick - We use carbon and oxygen isotope (δ13C, δ18O) data from carbonates and nitrogen and sulfur isotope (δ15N, δ34S) data from the oldest of rocks to investigate the environment of early biology.

Palouse Field TripPrincipal Investigator Kate Huntington - We measure earth surface and sub-surface paleotemperature using clumped isotope (Δ47) data from a variety of carbonate species.
