Symposium

From Sources to Scapes: Contributions of Light Stable Isotopes to Environmental Sciences

Over the past 30 years, measuring small variations in the distribution of rare stable isotopes has led to numerous breakthroughs in environmental sciences – from paleoclimatology to ecosystem ecology to biogeochemistry. Since 1997, the University of California, Davis, Stable Isotope Facility has aided researchers from around the world with the measurement of these small variations. In honor of the retirement of the facility’s founder, Dr. David Harris, the UC Davis Stable Isotope Facility hosted a symposium in December 2010, to explore the present and future of stable isotope research in natural sciences.

A reception and open house was held on Thursday evening, December 16, 2010, during which participants toured the Stable Isotope Facility laboratories. On Friday, the symposium opened with a series of invited presentations followed by an accompanying poster session. Keith Hobson (Environment Canada) discussed the application of isoscapes to animal migration in his keynote speech, entitled Using Stable Isotopes to Track Origins at Multiple Scales. The remaining five invited talks were from long-standing SIF partners – each focusing on the application of stable isotopes to environmental sciences. The symposium concluded with a banquet on Friday evening to honor the contributions Dave has made to the facility and stable isotope research.
