Applied Geophysics

Applied Geophysics covers a broad range of applications and methods related to exploration, site characterization, cavity detection, environmental problems and much more. Exploration can be for petroleum, minerals, groundwater and other resources of economic value. The scale of the target that the experiments are conducted over may vary from tens of kilometers to determine crustal thickness to a few meters to find a buried pipe. All types of geophysical techniques are employed, including seismic, magnetic, gravimetric, electrical, electromagnetic (EM) and radiometric ones.

Examples of ongoing research in applied geophysics at the Geophysics Program include improving hard rock seismic processing methods, characterization and monitoring of carbon dioxide storage sites, development of EM instrumentation and interpretation methods, borehole logging for rock properties, and development of new seismic acquisition methods. This work is generally of societal importance, but there are also many components of basic research within the activities. One example of this is using geophysics to better understand the geological history of the Scandinavian mountain belt by "looking" into its structure down to depths of tens of kilometers.
