Biogeophysics is a subdiscipline of geophysics concerned with how plants, microbial activity and other organisms alter geologic materials and affect geophysical signatures.[1]
Introduction
The activities of the microbes are measured using geophysical imaging techniques. A lot of these techniques are based on the measurement of electric potential anomalies, which in this case can arise from microbes, their growth, metabolic by-products, and microbially mediated processes. The primary way in which these anomalies are generated can be explained by the Electrical_double_layer electrical double layer. The effects are most visible when low frequency field is used as the surface charge of microbes is of low mobility.[2]
