Recommended Prerequisites

Knowledge in the field of Earth Sciences and general Physics.

Teaching Methods

Theoretical lectures with detailed exposition of the concepts and principles pertaining to geophysical methods and of their applications. Theoretical-practical and laboratorial courses in which students are introduced to the resolution of exercises concerning practical applications (with guidance). Field work in which students undertake data acquisition with some geophysical methods. Personal work involving the resolution of exercises on an autonomous base. Transversal to the different types of courses/work is the introduction of the student to the questions concerning the methodologies underlying geophysical methods, their potentialities and limitations, their use with a critical approach, and the need to adapt to each specific situation.

Learning Outcomes

To provide the fundamental concepts and principles on the main methods in exploration geophysics, as well as insight on their applications, their potentialities and limitations. To gain knowledge on essential processing and interpretation of data, as well as the acquisition concerning some fundamental methods.

Work Placement(s)
