International Workshop on Tracer Applications of Noble Gas Radionuclides, June 21-22, 2012, Argonne National Laboratory, Photo: Daniel Schwen

This workshop was organized in response to the recent technical advance in Atom Trap Trace Analysis (ATTA), an analytical method for measuring isotopes 81Kr, 85Kr and 39Ar.  The primary aim of the workshop was to discuss applications of ATTA to compelling scientific problems in the earth sciences. Topics discussed included the use of the noble gas radionuclides as tracers of groundwater, glaciers, oceans, as well as volcanic and geothermal processes.

The workshop agenda and pdf files of the presentation slides are available here. A whitepaper on "Tracer Applications of Noble Gas Radionuclides in the Geosciences" resulting from the workshop can be downloaded here.

The workshop was supported by Argonne National Laboratory, the National Science Foundation, and the University of Illinois at Chicago.
