University of Tennessee
Subsurface Observatory Science Lead
Terry Hazen, the Subsurface Observatory Science Lead, has a background in environmental microbiology, especially related to bioremediation and bacterial stress. Terry maintains close collaboration with the executive and project leads in administration, management, and operations of the project, focusing on accomplishing the goals and deliverables.
Terry’s work anchors ENIGMA’s ongoing field activities to install Subsurface Observatories as sampling portals into the field site for the high-resolution data collection on a time, space, and replicate schedule to allow for meaningful statistics. These observatories will allow ENIGMA researchers to work with samples and data collected directly from the automated samplers at a frequency that will allow for high-resolution observation of microbial processes.
Research efforts in the laboratory of Dr. Hazen at the University of Tennessee and Oak Ridge National Laboratory drive the ENIGMA SFA understanding of the program field site by providing detailed and often continuous analysis of the field site lithography, hydrology, meteorology, groundwater, and gas evolution chemistry and microbial interactions.
UTK directed laboratory-based analysis of these field samples will include molecular microbiology and analytical chemistry-related assays and techniques to understand the microbial community structure, including the emerging UMB fraction, abundance, and activity. In addition, this laboratory will serve as the base for PHREEQC/ModelMuse and RockWorks analysis for the generation of high-resolution 3D models of the lithography of the field site overlayed with transport models to determine the flow and presence of parameters of interest through the subsurface.
