Teaching Methods Frontal lessons; Demonstration of examples with simulated data; Real data visualization and processing using open-source software; Examples of field acquisition (if instrumentation is available).
Evaluation methods Verification of learning:
The exam will consist of an oral interview which will focus on verifying knowledge of the criteria, tools, and geophysical techniques illustrated during the course. Evaluation will be expressed as a fraction of 30.
Contacts/More Information Office hours will be decided after the beginning of the course. Students may request to schedule an appointment outside the official office hours by contacting the teacher by email.
