Using stable isotopes to understand Earth systems

  • 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 fly drones over the Greenland Ice Sheet to measure isotopes of water vapor, and to better understand water fluxes from the cryosphere.
  • 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
  • Laser-based cavity ring-down spectrometers.
