Applied Geophysics (GEOL-7136)

DESCRIPTION AND OBJECTIVES

This course is applied geophysics is designed to enable graduate students to get understanding for application of geophysical techniques to solving geoscientific problems in resource exploration and development, natural hazards, and pollution control. The course takes a practical, hands-on, field-oriented approach to show the applications of geophysics to these problems. For each topic, the course flow will proceed from basic principles (theory) through methodology and applications, to case histories. This course emphasizes applications, and keeps theory to essentials. The syllabus presents principles and operational procedures of each method initially, along with discussions of where the method is applicable, and is not applicable. Case histories will illustrate applications.

INTENDED LEARNING OUTCOMES

The student will be able to demonstrate an advanced understanding of the physical principles underpinning geophysical methods. Critically evaluate geophysical techniques, acquisition procedures, and survey designs for various subsurface targets. Process and analyse collected geophysical data. Employ appropriate modeling methodologies, and evaluate strengths, weaknesses, and limitations. Infer physical properties at depth and formulate geological interpretations from those properties.

COURSE CONTENTS

Study of geophysical features of the Earth including gravity, magnetic, and temperature fields. Geophysical methods.
