What This Document Is
These are lecture notes from GEOG 594, Introduction to Applied Geophysics at the University of California, Berkeley. This material provides a foundational overview of geophysical methods used to investigate subsurface conditions. It explores the principles behind various techniques and their applications across diverse fields. The notes represent a core component of the course, offering a structured presentation of key concepts.
Why This Document Matters
This resource is invaluable for students enrolled in introductory geophysics courses, or those seeking a solid grounding in the field. It’s particularly useful for understanding the theoretical underpinnings of geophysical surveys *before* delving into detailed data analysis or field work. Professionals in environmental science, engineering geology, and natural resource exploration will also find this a helpful refresher on fundamental principles. Accessing these notes will help you build a strong base for more advanced study and practical application.
Topics Covered
* Fundamental principles of applied geophysics and its relationship to remote sensing.
* An overview of major geophysical techniques – gravity, magnetism, seismic, electrical, and electromagnetic methods.
* The relationship between subsurface physical properties (density, susceptibility, velocity, resistivity) and geophysical measurements.
* Distinction between active and passive geophysical methods.
* Considerations for survey planning, including target identification and data acquisition strategies.
* An introduction to the challenges of geophysical interpretation, including non-uniqueness and resolution limitations.
* The benefits of employing multiple geophysical methods for improved accuracy.
What This Document Provides
* A clear introduction to the scope and purpose of applied geophysics.
* A comparative look at different geophysical techniques and their respective strengths.
* Discussion of the scales at which these techniques are most effectively applied.
