In resistivity surveying, vertical electrical sounding (VES) and electrical resistivity tomography (ERT) are two of the most common variants being deployed routinely in geophysical investigations. VES is essentially a 1D survey whereas ERT is a 2D survey. Many are familiar with both VES and ERT. I

Briefly describe the current situation of near surface geophysics

Exploration geophysics is an applied branch of geophysics, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties. It is most o
