Terry Hazen, discusses his journey with ENIGMA and current research interests within the SubSurface Observatory focus area.
Subsurface Observatory
Rainfall Impacts Hydrology Of Test Site More Than Field Sampling
ENIGMA researchers measured physical and geochemical effects of cone penetrometer testing on nearby shallow groundwater wells. They found that the effects of cone penetration on water level and conductivity were minimal.
New Platform Explores Ecological Drivers of Change in Microbial Communities
ENIGMA researchers assess mechanisms for microbial taxa and community dynamics using process models.
Mixed Nitrate and Metal Contamination Influences Operational Speciation of Toxic and Essential Elements
ENIGMA researchers compared the availability of elements in non-contaminated and acidic nitrate contaminated sediment and found that contamination impacted the bioavailability of essential elements.
Environmental bacteria may have candidate genes for bioremediation
ENIGMA researchers identified important genes for improving Chromate resistance in genetically diverse bacteria through experimental evolution.
Examining adaptations of a dominant bacterial species at a contaminated subsurface site
Leveraging comparative genomics, community analysis, and geochemical data to understand adaptations that facilitate survival of a dominant community member in the contaminated Oak Ridge Reservation subsurface.
