My research addresses the cycling of heat, fresh water, and carbon by the oceans, the dynamics and consequences of abrupt climate change, and the use of 14C as a tracer in the carbon cycle. I also direct the CU-INSTAAR Laboratory for AMS Radiocarbon Preparation and Research (NSRL). In addition to supporting the activities of my own research group, the lab provides analytical services to members of the CU community and to outside users. A major activity in the lab is the processing of air samples from the NOAA Global Greenhouse Gas Reference Network as a means of detecting recently added fossil fuel derived CO2 in the atmosphere.
