TL;DR: In this paper, the utility and resolution of different geoelectrical methods in mapping contaminant distribution in the subsurface, and provides a window into the processes that may control their response at a site in Central Michigan.

TL;DR: In this paper, the authors investigated the vertical distribution of bulk conductivity, TDS, and specific conductance in groundwater, and concluded that biodegradation processes can impact both electrolytic and surface conduction properties of contaminated sediments and these two factors can account for the higher bulk conductivities observed in sediments impacted by hydrocarbon.

TL;DR: A recent review of the field of biogeophysics focuses on geophysical interrogation of microbial processes, including direct detection of microbial cells and biofilm formation, microbial metabolic by-products, microbe-mediated redox processes, and biogeochemical and microbemineral transformations as mentioned in this paper.

TL;DR: In this article, high-resolution aeromagnetic data from the nascent Okavango rift in northwest Botswana provide an unprecedented view of rift kinematics during the incipient stages of continental extension.

TL;DR: In this paper, the effect of microbial processes on electrical properties of unconsolidated sediments was investigated in a laboratory experiment consisting of biotic and abiotic sand columns, and the results indicated that interpretation of geoelectrical data from near surface environments should consider effects of microbial process.
