Syllabus 4130 Introduction to Geophysics.
ReferenceTexts. Lowrie-Fundamental of Geophysics; Kearey and Brooks- An introduction to geophysical exploration; Burger, Sheehan and Jones: Introduction to Applied Geophysics; Stacey and Davis- Physics of the Earth.
Grading: Each half of the class will have assignments in the form of homeworks based on classwork. A score of 50% will be assigned to the homeworks and class participation, and a score of 50% will be assigned to the quiz/exam that terminates each half of the class. Sheehan and Bilham will assign final grades based on the average score for each half of the class. The first half of the class will use the computer lab to solve problems or undertake experiments each week.
