Geophysical imaging 1

The aim of this module is to provide a basic understanding of geophysical imaging of geological formations, both near-surface and on a lithospheric scale. The focus is 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 practical case study will highlight the importance of combining these methods to provide the best possible description of the environment and its properties, particularly in terms of fluids.

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

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

Continuous assessment.
