MAGNETO-TELLURIC METHOD What is the Magnetotelluric (MT) method? Magnetotelluric (MT) method involves measuring the response at the surface of the Earth to time-varying electromagnetic waves in the subsurface generated by natural and man made (artificial) sources. We can consider the Magnetotelluric (MT) method as the electromagnetic method, since it comprises two components such as magnetic and electric fields, with the electric field in Magnetotelluric (MT) method is associated with telluric currents .  However electromagnetic and magnetotelluric methods have proved slightly some similarity and clear differences. If you want to know these comparisons in clear and simplified way check and visit to Comparative Geophysics eBook . Magnetotelluric (MT) signals Based on the type of sources of Magnetotelluric (MT) fields, Magnetotelluric (MT) signals can be categorized into two (2) forms.  1.  Natural Magnetotelluric (MT) signals These originated naturally from external fie...

Geophysics is simply the study of the Earth by applying physics principles. Geophysics is the field of geoscience (Earth science) that in one way or another is related with other multidisciplinary natural and planetary science subjects such as environmental science , astronomy , Biology , geography , chemistry . This post will  describe the career path regarding geophysics , as there are interesting things you may want to hear. I hope we will be together until the end of this conversation. Become a Geophysicist Sometimes it gets overwhelming when it comes to know how you can become a geophysicist . To become a profession geophysicist you have to pursue a career in geophysics at least at undergraduate level, Bachelor's degree. You should have atleast higher education undergraduate majors degree in geophysics, geology , geoscience, physics. Also if you have multiple degrees in geophysics and geology is also a good way too, it will reach you where you want to go. This is an entry lev...

Ground-Penetrating Radar (GPR) is the non - destructive geophysical technique that applies radio-waves to image the subsurface. It is the most modern and rapidly developing geophysical technology.  GPR technology uses a transmitter that emits pulses of high frequency electromagnetic waves into the subsurface. Transmitter is either moved slowly across the ground surface or moved at a fixed station interval. GPR is used to investigate depths from the first centimeters to hundreds of meters. The simplicity and speed in carrying out fieldwork using the GPR method combined with the lightweight of the equipment set make it possible to operate GPR surveys on multi environments such as  the ground, from the air, underwater and in space. Ground penetrating radar (GPR) System A GPR system (a radar) is a device for non-destructive subsurface imaging that operates by electromagnetic waves. GPR depending upon configuration comprised of radio frequency (RF) transmitter , receiver, ADC...
