When: August 17 - December 11, 2015. Lecture: Mo.We.Fr. 9:05-9:55 am

Where: ES&T L1175 (lower-level 1)
Instructor Office Hours: Will be held in my office (see above) on Wednesdays 1 - 2 pm, and Thursdays from 1:30 - 2:30 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.

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.

16 11/30 - 12/4 Course Wrap-up: Emergent geophysics
Graduate Student lectures on Geophysical Research
17 12/11: 8 - 11 am (Friday) Final


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 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.


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.


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.
