  • We study the carbon cycle by measuring stable isotopes of greenhouse gases from a global air sampling network.

  • We study climates of the past by measuring stable isotopes of water in ice cores from Greenland and Antarctica.

  • We measure methane on a local scale to study the sustainability of oil and gas extraction in the Rocky Mountain West.

  • We continually improve our methods with new, automated techniques for measuring environmental stable isotopes.

  • We provide analytical services to scientists and institutions around the world.

We excel at measurements of

  • δ13C and δ18O in ambient or pure carbon dioxide

  • δ13C of atmospheric methane and local sources of elevated methane

  • water from ice cores as well as environmental waters

Our instrumentation includes dual-inlet and continuous-flow isotope-ratio mass spectrometers, as well as multiple laser-based cavity ring-down spectrometers.
