Geophysical Imaging 1

This module aims to provide the basics of geophysical imaging of geological formations, both near-surface and lithospheric. We will focus on seismic methods (volume and surface wave tomography, receiver functions, ambient noise), gravimetry and magnetotellurics. We will also present the basics of seismic reflection (acquisition and processing). A case study seen during the lab will highlight the importance of combining these methods to best describe the environment and its properties, particularly in terms of fluids.

- To know the principle of seismic/seismological, gravimetric and magnetotelluric geophysical methods
- Notions of signal processing
- Notions of direct and inverse problem
- To know how to jointly interpret geophysical data on a case study

- Properties of waves (amplitude, frequency, wavelength, velocity, reflection and refraction ...)
- Ohm's law, resistance, intensity and voltage of a current
- Newton's first law, notion of the geoid and gravimetric anomalies

Continuous assessment.

- seismic / seismological
- gravimetric
- electrical and magnetotelluric
- Notions of direct and inverse problem
- Know how to interpret jointly geophysical data on a case study
