We are honored to cite Thure E. Cerling and James R. Ehleringer for empowering generations of students with a rich and interdisciplinary understanding of stable isotope techniques and their applications. Stable isotope data span the Earth system and provide unique and quantitative windows to biological and geochemical processes. As -world--renowned scientists, Cerling and Ehleringer pioneered isotope studies and made them invaluable to biogeochemistry, ecology and paleoecology, forensics, and the climate sciences. Yet even as these fields expanded rapidly in the 1990s, Cerling and Ehleringer recognized that stable isotope biogeoscience was not open to all. Students at many smaller or foreign universities lacked access to expertise, training, and analytical resources. They also recognized that students from different disciplines had much to learn from each other. Therefore, they brought students together with top isotope scientists from many fields for an intensive course on isotope theory, analysis, and interdisciplinary applications. They created networks of collaborations and friendships among scientifically, culturally, and internationally diverse young scientists, who have gone on to become leaders in a wide range of the geophysical sciences.
Thure Cerling and Jim Ehleringer are the intellectual, inspirational, and organizational forces behind a -hands--on, intensive, -2-week summer course offered annually since 1996. “Stable Isotope Biogeochemistry and Ecology” (affectionately known as IsoCamp) has trained more than 750 students from over 250 institutions in 37 countries across a multitude of scientific disciplines. The 2 weeks of IsoCamp include morning lectures from leading scholars on foundation principles, theory and process, and applications of stable isotope analyses. Students spend each afternoon in the field or in the isotope laboratory, where they are exposed to real-life problems, make their own isotope measurements, and participate in team-based projects. IsoCamp gives students both the fundamental knowledge needed to understand isotopic variations and the confidence to present interpretations of the results to their peers. Students advance rapidly from tentative newcomers, fueled by lectures, discussions, and growing experience in the field and lab. By the second week, students have gained the ability to envision their own projects and decide how best to apply an arsenal of available isotope methods and have built a lasting esprit de corps as they scramble to complete their projects before presentation.
Thure Cerling and James Ehleringer have created a transformative learning and networking experience for multiple academic generations of researchers and established the archetypical model of a successful summer short course for colleagues around the country.
