Scientists from University of Wyoming, CSIRO, and Stanford University recently presented a success story in the Geoscientists Without Borders program at the annual Society for Exploration Geophysicists meeting in Denver. Led by Andrew Parsekian and Aaron Davis, the team demonstrated a combined geophysical approach for aquifer location and characterization incorporating GMR measurements with ancillary airborne magnetic and TEM data. The project was focused in Southern Australiaâ€™s remote and arid Anangu Pitjantjatjara Yankunytjatjara (â€œAPYâ€) where aboriginal populations depend critically upon groundwater resources. GMR data were used to reliably determine the presence of groundwater near anomalies identified in the airborne magnetic and TEM data. The short dead time of the GMR and CPMG pulse sequence proved important for detecting very short NMR signals influenced by the magnetic geology. The team produced a short video of the project.
The Society for Exploration Geophysicists program, Geoscientists Without Borders, supports humanitarian applications of geoscience around the world. The program is featured, with a highlight of the APY lands project, in the December issue of the societyâ€™s journal The Leading Edge.
