Who we are

The Geochemical and Environmental Research Group (GERG) is a center of excellence in applied geosciences within the College of Geosciences of Texas A&M University. GERG, founded in 1981, focuses on applied interdisciplinary research in the ocean and environmental sciences. As part of GERG's mission in education, graduate and undergraduate students are encouraged to interact with GERG's scientists and staff in their study and research. Students at GERG are mentored and advised in their study and research in many areas by the staff and scientists at GERG. GERG benefits from the leadership developed by the students and the dynamic and diversity of student activities.

What we do

The Geochemical and Environmental Research Group (GERG) provides research and education to the public. Scientists at GERG conduct basic and applied research for both private and government entities in the fields of ocean science, environmental sciences, and resource geosciences. The combination of private and government research activities at GERG has led to a unique combination of service, education, and research expertise.

GERG is organized as three interrelated core competencies working together to provide capabilities including field data acquisition, data analyses, and data interpretation. Current research projects conducted at GERG encompass chemistry, biology, oceanography, geology, geochemsitry, meteorology, and toxicology.
