GEOSCIENCES RESEARCH DIV.
- Quantification of abrupt temperature changes using measurements of nitrogen and argon isotopes in ice cores
- Mechanisms of millennial-scale climate oscillations and climate bifurcations
- Pleistocene global carbon cycle variations deduced from oxygen and noble gas measurements in ice cores
- Reconstructing changes in atmospheric noble gas composition over the past million years from air trapped in glacial ice
- Radiocarbon of methane in late glacial-age ice as a test of the sedimentary methane clathrate degassing hypothesis.
- Isotopic fractionation of air in polar firn (snow) due to gravitational settling and thermal diffusion, with implications for gas age-ice age differences and leads and lags of climate versus greenhouse gases in ice core records
