Elliott Barnhart
Biography
Dr. Elliott Barnhart is a research hydrologist (microbiologist) at the Wyoming Montana Water Science Center in Helena, Montana. His research focuses on using new DNA technology to better understand ecological processes, promote energy development and examine environmental issues. His research specifically focuses on (1) understanding how microorganisms turn coal to natural gas underground, (2) developing and testing new DNA sampling and analytical equipment, and (3) investigating the prevalence of microorganisms, pathogens and invasive species in different ecosystems.

Environmental DNA (eDNA): Combining Technology and Biology to Detect Aquatic Invasive Species and Pathogens
Using DNA, USGS researchers are able to detect the presence of invasive species in aquatic ecosystems. The DNA they use is literally floating around in the environment and is called environmental DNA (eDNA) and is a powerful tool for the early detection of invasive species and pathogens, which can cause serious ecological and economic damage. USGS researchers are also combining the use of eDNA...
Using Robots in the River: Biosurveillance at USGS streamgages
For more than a decade, researchers around the world have shown that sampling a water body and analyzing for DNA (a method known as eDNA) is an effective method to detect an organism in the water. The challenge is that finding organisms that are not very abundant requires a lot of samples to locate this needle in a haystack. Enter the "lab in a can", the water quality sampling and processing...
Microbial Methanogenesis and Strategies for Enhancements
Microbial (biogenic) natural gas is present in shale, coal and petroleum reservoirs and is estimated to account for 20% of the world’s natural gas resources. We provide hydrological, geochemical and microbial information related to the production of biogenic natural gas and new methods to monitor and enhance the production of this energy resource. Generating microbial methane at a faster rate...
New Patent Helps Coalbed Methane Research
Far underground, in a Wyoming well-bore drilled through rock and coal, exciting research is bubbling up. USGS researchers are studying how bacteria and other microbes may play a role in the formation of natural gas from coal, and they’re using one of USGS’ newest patents to do it. This patent is the subsurface environmental sampler, or SES.
Use of Robotic DNA Samplers That Can Rapidly Detect Invasive Aquatic Species
USGS researchers and their collaborators demonstrated the efficacy of using robotic environmental DNA samplers for bio surveillance in freshwater systems, showing that samples collected, processed, and preserved by robotic sampler detect organism DNA in the environment at rates comparable to those collected traditionally by human technicians.
