If you would like a book that gives you a very vague overview of geophysical techniques, that doesn't explain how the physics is applied to the problem this is the book for you. It goes through various geophysical techniques but lacks the explaination that goes along with the technique. Very few equations for the application of the material, and when equations are introduced the author regrets to explain their meaning or how it applys to the situation. This book is terrible for the geophysicist student/professor but may be good for a person who is mathematically challenged and read about techniques but have no clue how to apply them to real world situations. Would have given this book 0 stars if it was an option.
