Isotopics

Isotopes are an excellent way to understand things about ecosystem processes. Isotopics is an area that is constantly evolving and we strive to push the bounds of this field by developing new methods while also building upon olds one, in an effort to better understand our environment based on its isotopic signature. We use a variety of stable isotope techniques to ask both process based and global scale questions .
