Looking into the Earth: An Introduction to Geological Geophysics, by M. Mussett and M. A. Khan, Cambridge University Press, Cambridge, 2001, 608 pp.
Fundamentals of Geophysics, 2nd edition by W. Lowrie, Cambridge University Press, 2007, 381 pp.
Course description:
The course gives an introduction of the fundamental principles of each major branch of geophysics: seismology, gravitation, magnetism, electrical and thermal properties. Emphasis is given to geodynamics and plate tectonics. A comprehensive overview of geophysical techniques is also given to better understand the relation between measurements taken at the Earths surface and physical properties investigated in relation to the Earths interior. The course is designed for advanced undergraduate students with basic grounding in math and physics. Sets of practical exercises will be completed at the end of each chapter and will be designed to give students a practical approach to geophysical methods while enhancing their skills in quantitative problem solving.
Course Objectives:
1) To provide an overview of the theoretical basis and principles of geophysical methods; 2) to examine how different types of geophysical observations offer constraints on Earths structure and composition; 3) to present an overview of the plate tectonics framework and its dynamics; 4) to become familiar with case studies and exercises related to the use of geophysics for the study of Earths internal dynamics.
Method of instruction:
Combination of theory and practical exercises in the classroom. Practical exercises will be initiated in the classroom towards the end of selected lecture sessions (see intended course calendar for details). Students will be responsible for completing and submitting the exercises as homework assignments.
Contents:
The general course structure will be as follows (see intended course calendar for further details):
1) Introduction: general overview of geophysical data acquisition and processing
2) Seismology: waves, earthquakes, refraction and reflection methods and interpretation
3) Gravity: gravitational field, anomalies, isostasy, methods and modeling
4) Magnetism: magnetic field, geomagnetism, anomalies, methods, paleomagnetism
5) Electrical electromagnetic methods: heat transfer, flow, geoelectricity, methods
6) Radioactivity: radioactive dating and surveying
7) Geothermics: heat flow and temperature, geothermal energy

Attendance:
Attendance to all lectures is required and will affect your grade.
Courtesies:
Please turn off cell phones, pagers, mp3 players and PSPs before coming to class. Lateness is disruptive to other class participants, so please be on time. Lateness may also affect your grade if you miss quizzes.
Readings and practical exercises:
Lectures will be based on selected chapters from the textbook. Material for practical exercises will be provided whenever necessary and will be based on selected textbooks from the bibliography list. Assigned text readings and exercises are to serve as reference material to lecture topics. In the readings assigned, you are only responsible for the material discussed in class.
Lecture notes:
A pdf version of the lecture notes will be posted on Blackboard the day prior to each lecture. You may choose to print them out and bring them to class, or wait until the end of the class. Announcements and grades will also be posted on Blackboard.
Policies:
Academic policies and regulations for this class reflect those shown in the FAU University Catalog. For more information visit: http://www.fau.edu/academic/registrar/catalog/academics.php
