On a changing planet, supporting research using stable isotope analysis is key to advancing our understanding of Earth’s complex deep past and rapidly approaching future. Stable isotopes are used to detect variations and track movements of the basic elements of life (nitrogen, carbon, oxygen) as they cycle through biological, chemical, and physical systems. Scientists use this information to study topics such as photosynthesis, carbon storage and cycling, and the past and present interactions that plants, animals, and humans have amongst each other and their environment. Stable isotope analysis is one of the most innovative avenues of environmental research today and is rapidly expanding as a powerful investigative tool with multi-disciplinary implications. A new Isotope Ratio Mass Spectrometer system, based in Latin America at the Smithsonian Tropical Research Institute (STRI) and cp-funded by Tarbaca Indigo Foundation, will greatly expand investigative capabilities and empower researchers in the Neotropics to directly take part in the forefront of isotope research.
