Geophysical Methods

Magnetometry is a geophysical method that measures variations in the Earth's magnetic field caused by the presence of buried metal objects.

Electrical Resistivity Imaging is a geophysical method that measures the electrical resistivity of the subsurface to identify variations in soil composition and archaeological features.

Ground-Penetrating Radar is a geophysical method that transmits and receives high-frequency electromagnetic waves to generate detailed images of the subsurface.

Seismic refraction surveys measure the velocity of seismic waves traveling through the subsurface to determine variations in soil composition and geological structures.

Ground-Penetrating Radar utilizes electromagnetic waves to generate high-resolution images of the subsurface, allowing for the detection of buried objects and anomalies.

Magnetometry surveys measure variations in the magnetic susceptibility of the subsurface to identify buried metal objects and geological features.

Microgravity surveys measure variations in the Earth's gravitational field to identify subsurface cavities and voids, such as tunnels and chambers.

Electrical resistivity tomography surveys measure the electrical conductivity of the subsurface to identify variations in soil composition and geological structures.

Seismic reflection surveys generate cross-sectional images of the subsurface by transmitting and receiving seismic waves, allowing for the identification of geological structures and buried objects.

Seismic reflection surveys measure the velocity of seismic waves reflected from subsurface layers to generate cross-sectional images of geological structures and buried objects.

Ground-Penetrating Radar is commonly used to detect buried metal objects and archaeological features due to its ability to generate high-resolution images of the subsurface.

Microgravity surveys measure variations in the Earth's gravitational field, which are influenced by variations in subsurface density, allowing for the identification of cavities, voids, and geological structures.

Magnetic Resonance Imaging is a geophysical method that utilizes magnetic resonance to generate images of the subsurface, providing information about soil composition and moisture content.

Magnetic resonance imaging surveys measure the magnetic susceptibility of the subsurface, which is influenced by the presence of water, minerals, and organic matter, allowing for the identification of geological structures and buried objects.

Microgravity surveys are commonly used to detect subsurface cavities and voids in archaeological contexts due to their ability to identify variations in subsurface density.
