Field Course
A.Y. 2024/2025
Learning objectives
Knowledge and understanding: learn how to plan, design, execute and interpret a geophysical survey, from the selection of the methods to be applied to the interpretation of results.
Applying knowledge and understanding: the acquired knowledge allows to approach correctly the planning, design, execution and interpretation of a geophysical survey and to clearly communicate the results.

Expected learning outcomes
Making judgements: the student is able to design and plan a geophysical survey, e.g. selecting the most appropriate geophysical methodologies, acquisition settings and survey layout; furthermore, the student is able to evaluate the optimal processing and interpretation approaches for solving a geophysical problem and the best way of presenting the results.
Communication skills: The student is able to clearly communicate the results of a geophysical survey, both orally and with a written report that illustrate data acquisition, processing and interpretation.
Learning skills: Give the student the ability to learn autonomously topics that can not be dealt with during the lessons/field acquisition, due to the limited time available, and also give him/her the ability to deepen the ones discussed.
