We are conducting a geophysical monitoring experiment to investigate the sensitivity of electrical geophysical measurements to the biodegradation of oil from the Deepwater Horizon spill that has accumulated in beach sediments. This study builds on previous work of our team members that has demonstrated the sensitivity of electrical geophysical measurements to the biodegradation of hydrocarbons.

We have established a long-term geophysical monitoring site on a remote beach area contaminated by oil from the Deepwater Horizon oil spill. Grand Terre I is an uninhabited island that was heavily impacted by the oil spill. It provides a “noise” free location for investigating the potential of non invasive electrical geophysical methods for long term monitoring of attenuation of the oil spill. The zone of oil contamination is located ~0.4-0.6 m below the surface and this contaminated layer is be bound by cleaner sand layers.
We have installed and maintained an autonomous, continuous resistivity monitoring system at this site. We also installed temperature and geochemical sensors to support the interpretation of the resistivity dataset. We have also performed an electromagnetic (EM) terrain conductivity survey using a multi-frequency instrument in order to obtain a rapid characterization of the spatial extend of the oil plume.
