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:
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“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)
“When I survey the wondrous cross
On which the Prince of Glory died,
My richest gain I count but loss,
And pour contempt on all my pride.”
—Isaac Watts (1674–1748)
