Coal fires pose great threats to valuable energy resources, the environment, and human
health and safety. They occur in numerous countries in the world. It is well-known that China …

This paper reviews the application of the algorithm particle swarm optimization (PSO) to
perform stochastic inverse modeling of geophysical data. The main features of PSO are …

Filling a gap in the karst literature, this book describes methods most appropriate for use in
karst terrains. These include methods that are basic to all hydrogeological studies, such as …

The self-potential method enables non-intrusive assessment and imaging of disturbances in
electrical currents of conductive subsurface materials. It has an increasing number of …

Accurate map** of the electrical conductivity and of the redox potential of the groundwater
is important in delineating the shape of a contaminant plume. A map of redox potential in an …

“Biogeophysics” is a rapidly evolving Earth science discipline concerned with the
geophysical signatures of microbial interactions with geologic media. It spans the …

Microorganisms participate in a variety of geologic processes that alter the chemical and
physical properties of their environment. Understanding the geophysical signatures of …

In situ measurements of redox potential are rather difficult to perform and provide only
sparse information on its spatial distribution. To delineate redox fronts in a contaminant …

Studying the forest subsurface is a challenge because of its heterogeneous nature and
difficult access. Traditional approaches used by ecologists to characterize the subsurface …

The self-potential (SP) method is a passive geophysical method based on the natural
occurrence of electrical fields on the Earth's surface. Combined with other geophysical …
