Stable Isotope Geosciences Facility

Established on the TAMU campus in College Station in 2009, the Stable Isotope Geosciences Facility (SIGF) is designed to provide accessible, reliable, and high-quality stable isotope measurements and training for faculty, staff, and students at Texas A&M and within the community. It is a facility where state-of-the-art methodologies and technological developments in stable isotopes can be applied to important societal problems related to energy, ecology, Earth history, and the environment.

Beyond the TAMU community, the SIGF has strong research links with scientists and students from other universities and industry who require accurate and precise measurements. The facility continues to be recognized for its quality work and research.
