f Biogeochemical Controls on Magnetic Susceptibility Variations across a Hydrocarbon Contaminated Site

Biogeophysical investigations over the last decade have provided evidence documenting that geophysical technique can be used to assess in-situ biogeochemical processes. In this study, we investigated a site contaminated by crude oil at Bemidji, Minnesota where intrinsic bioremediation is known to occur and iron is the dormant electron acceptor process.
