Types of Geophysical Survey
There are many methods and types of instrumentation used in geophysical surveys. Technologies used for geophysical surveys include:
- Seismic methods, such as reflection seismology, seismic refraction, and seismic tomography.
- Seismoelectrical method
- Geodesy and gravity techniques, including gravimetry and gravity gradiometry.
- Magnetic techniques, including aeromagnetic surveys and magnetometers.
- Electrical techniques, including electrical resistivity tomography, induced polarization and spontaneous potential.
- Electromagnetic methods, such as magnetotellurics, ground penetrating radar and transient/time-domain electromagnetics.
- Borehole geophysics, also called well logging.
- Remote sensing techniques, including hyperspectral.

“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)

“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
