Elective
1st Cycle Studies
Recommended Prerequisites
Knowledge in the field of Earth Sciences and general Physics.
Teaching Methods
Theoretical classes with detailed exposition of the concepts and principles pertaining to geophysical methods and of their applications. Theoretical-practical classes in which students are introduced to the resolution of exercises concerning practical applications (with guidance). Field work in which students have contact with data acquisition with some geophysical methods. Personal work involving the resolution of exercises on an autonomous base.
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.
Acquiring capabilities in synthesis and analysis, representation and transmission of information, problems solving, critic reflection, autonomous comprehension of new situations, practical application of theoretical knowledge.
