When: August 21 - December 6, 2012
Lecture: Tues/Thurs, 9:35 - 10:55 am
Where: ES&T L1116
Instructor Office Hours: Will be held in my office (see above) on Tuesdays from 11 am - 12 pm, and
Wednesdays from 1:30 - 3 pm, or by appointment.
Teaching Assistant Office Hours: ES&T 2120, Tuesday 1 - 2 pm and Thursdays 11 am - 12 pm, or by appointment.
Course Objectives:
This course is an introduction to methods used to visualize and understand the history, shape, mechanical structure,
and dynamics of the solid-earth system. We will discuss how geophysical tools, including seismology,
gravity, magnetism, heat flow, geochronology, and geodesy, are used to understand the age, whole-earth
and near-surface structure, and to quantify the kinematics and dynamics of plate tectonics.
Prerequisites
- Physics 2212: Introduction to Physics I
- EAS 2600: Earth Processes and Products
Required Text:
- Fowler, C.M.R., The Solid Earth: An Introduction to Global Geophysics, 2nd Edition, Cambridge University Press, 685 pp., 2005.
Class Communications:
You will occasionally receive class information
via email to your prism account. Because this information may not be communicated
in class, you should be sure to read messages identified as [EAS: Geophysics].
In emailing me for class, please add [EAS: Geophysics] to the subject line and
identify yourself by name in the message since not all prism accounts clearly
identify the email's author.

EVALUATION:
Undergraduate section: Your grade is based on homework (30%) and 3 exams (70%).
Graduate section: Your grade is be based on homework (30%), 3 exams (60%), and an oral presentation (10%).
The Undergraduate and Graduate sections will be graded and curved independently.
Homework:
Homework will be assigned about every 2 weeks and will be due one week
from assignment. Graduate students will be assigned additional problems in each of the assigned problem sets.
Late homework will not accepted without prior authorization.
See the academic honesty section (below), for information on working together.
Exams:
There will be three exams in total, 2 mid-terms administered during class time,
and 1 final exam administered during finals week. The exams are equally weighted, with the lowest
score being dropped. Thus, if you are satisfied with your course performance after the second mid-term
exam, there will be no need for your to take the final.
Keep in mind that while the first two exams will focus on material covered since the previous exam, the final exam
will be comprehensive, and about 50% longer.
Missed exams will receive a score of zero, and will be considered your dropped exam.
ACADEMIC HONESTY:
General: It is expected that all students are aware of their individual
responsibilities under the
Georgia Tech Academic Honor Code,
which will be strictly adhered to in this class.
Problem Sets: Students are encouraged to work together on developing
solutions to problem sets; however, the solutions/answers that are turned
in must be the work of each individual. Include the name of individuals consulted
for each problem that you sought aid in answering (including the instructors).
Exams: All information required for exams will be supplied. Reference
to texts or other documents during exams is strictly forbidden. The use of
electronic devices (e.g. cellular phones, computers etc.) other than
non-programmable calculators during exams and quizzes is not allowed.
The complete text of the Academic Honor Code may be found at http://www.honor.gatech.edu/.
