Doctorate in Environmental Sciences

Seminar Series

The Environmental Sciences Ph.D. Program hosts a weekly seminar series during the academic year featuring presentations by individuals (students, faculty and invited guests) discussing their research within the environmental sciences. These presentations are free and open to the public.

Application of Noble Gas Geochemistry to USGS Scientific Investigations

Dr. Andrew Hunt,
US Geological Survey

Application 1 – Groundwater Dating
As part of an investigation into the geochemistry of ground waters in the Arbuckle-Simpson aquifer, a set of dissolved gas and tritium samples were collected from existing wells and springs to determine helium-3/tritium ground water ages.

Application 2 – Tracer of Deep Fluid Flow in the Crust
In an effort to clarify the possible role of amagmatic geothermal systems as the source of young to modern epithermal Au mineralization, noble gas and fluid chemistry samples were collected from active, amagmatic geothermal systems in Nevada as well as modern magmatic geothermal systems in California.

Application 3 – Gas Hydrate Fingerprinting
Methane release from gas hydrates undergoing dissociation in response to global warming could act as a critical feedback mechanism that further exacerbates warming. To determine whether methane emissions can be linked to dissociating hydrate requires a way to distinguish it from other methane sources. Here, we investigate noble gas partitioning in laboratory-synthesized methane hydrate as a potential fingerprinting method to distinguish gas released from methane hydrate from other methane populations.

Application 4 – Basin Scale Investigation of Groundwater Migration in Oil and Gas Production Areas
Renewed oil and gas production/development in Colorado has highlighted a need to evaluate groundwater resources that overlie current and future production reservoirs in order to define the potential impacts of development activities.
