Geophysical Survey Applications

Geophysical survey applications refer to the use of non-invasive geophysical techniques, such as seismic, magnetic, and electrical methods, to investigate subsurface geological structures and processes. These applications are employed in various fields, including environmental studies, archaeology, and natural resource exploration, to gather data about the Earth's physical properties.

Key Terms

Seismic Waves
Waves of energy that travel through the Earth, used in seismic surveys.

Example: P-waves and S-waves are types of seismic waves.

Magnetic Field
The area around a magnet where magnetic forces can be detected.

Example: Earth's magnetic field is used in magnetic surveys.

Electrical Resistivity
A measure of how strongly a material opposes the flow of electric current.

Example: Soil resistivity can indicate water content.

Ground Penetrating Radar (GPR)
A geophysical method that uses radar pulses to image the subsurface.

Example: GPR is often used in archaeology to locate buried structures.

Data Interpretation
The process of making sense of collected data to draw conclusions.

Example: Geophysicists interpret seismic data to locate oil reserves.

Anomaly
A deviation from the expected pattern in geophysical data.

Example: A magnetic anomaly may indicate the presence of minerals.
