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.

Famous quotes containing the words types of, types and/or survey:
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
—Albert Camus (1913–1960)
“The rank and file have let their servants become their masters and dictators.... Provision should be made in all union constitutions for the recall of leaders. Big salaries should not be paid. Career hunters should be driven out, as well as leaders who use labor for political ends. These types are menaces to the advancement of labor.”
—Mother Jones (1830–1930)
“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
