Labs:  There are no labs per se, but assignments will be assigned every week (Thursdays).

Office Hours: By appointment only.

Textbook: Lowrie, William (1997), Fundamentals of Geophysics, Cambridge University Press.

Recommended Bibliography: Peter M. Shearer (1999), Introduction to Seismology, Cambridge University Press; Seth Stein & Michael Wysession, An Introduction to Seismology, Earthquakes, and Earth Structure, Blackwell Publishing.

Course Description:
    The main goal of this introductory course in geophysics is to help our undergraduate and graduate students understand the fundamentals of geophysics. Our Department is one of the only in the SE US that offers a major degree in geophysics, and yet is still lacking a comprehensive, theoretical introductory level geophysics course. This new experimental course will test the level of student interest in the subject, and will assess the necessity of a theoretical geophysics course for our students, and particularly, for our geophysics majors.

Logistics:   

    This course is designed as a 500 introductory-level course, and will target our geophysics majors as well as our graduate students. Students will be provided with an understanding of applications of physics to studies of Earth structure and dynamics from crust to core. Laboratory sessions provide hands-on experience in measurement and analysis of geophysical data. Although this course will provide fundamental theory and background of geophysical methods, the majority of the assignments will require the use of computers since geophysics can be computationally involved.

Objectives:

(1) To help our students develop the ability to think critically, objectively, and quantitatively.
(2) To provide an introduction to the physics of the earth in light of constraints from the seismology, gravitational and magnetic fields. The fundamentals of wave propagation in earth materials will be developed and applied to inferring earth structure.
(3) Develop the student’s ability to understand and assess a given geologic problem and determine the appropriateness of the geophysical methods to be applied in solving that problem.
(4) To provide students basic knowledge of the principles of geophysics, geophysical methods, instrumentation, and geophysical field procedures.

Exams:  All exams will be based on the lectures and textbook readings. There will be a total of two mid-term exams and a final exam. The exam scores will be equally weighted, and will count for 45% of the final course grade.

Grading:   

Exams 45%
    Exercises 40%
 Quizzes 10%
         Participation 5%

 

 

 

 

Assignments: Assignments will be handed out most every week. A week is allowed to complete the assignments, unless otherwise specified. A penalty of 5% per day after the due date will be applied unless a very good reason is presented in advance for not being able to complete the assignment.

Graduate vs. Undergraduate Requirements: Graduate students should do all assigned problems, including bold-faced ones. Undergraduates may leave out the bold-faced problems, but are welcome to do them for extra credit.

Attendance: Mandatory! Attendance sheet will be signed every lecture time.

Software: Lab exercises represent the main part of this course. Practical demonstrations will make use of some specialty software.

Pre-Requisites:

    MATH241 or 250; Co-requisite:   MATH242
