Subdiscipline of exploration geophysics focusing on the geophysical signatures resulting from microbial communities and their interactions with geologic media.
Geophysical imaging techniques have the potential to measure not just the subsurface physical and chemical properties, as geophysics is conventionally used, but also microbes, microbial processes, and microbe-mineral interactions. “Biogeophysics” is defined here as a rapidly evolving discipline of exploration geophysics concerned with the geophysical signatures of microbial communities and their interactions with geologic media that combines the fields of microbiology, biogeoscience, and geophysics (Atekwana and Slater 2009) (Fig. 1). Within this context, biogeophysics examines the links between dynamic subsurface microbial processes, microbial-induced alterations to geologic materials, and geophysical signatures. We note that the term biogeophysics is also used in other disciplines (a) to...
