GG652: Gravity, Magnetic, and Heat Flow, Spring 2013
Instructed by Garrett ApuzenIto, 11:0012:15 a.m., Tue/Thu POST 810
Office hours:
11:3012:30 MWF Course
Objectives: •Teach fundamental theory as well as practical
applications of gravity, magnetics, and heatflow
•Improve skills in independent learning, critical
and quantitative reasoning, and communication Homework: Homework problems will be discussed on Thursdays,
the day they are due. Be prepared to
present your work 

and/or ask questions about problems you tried but did not
complete. Please complete your work before
class; class is not the time to come and learn how to do the homework, that’s
what office hours are for. You will
have the opportunity to turn in revised homework for full credit at the end of
the semester. You are also encouraged to
help each other just so long as the work you turn in is yours alone.
Exams: There will be
no exams. Your “final” will be your class project and revised homework.
Class
Project: The purpose of this project is to apply what you have learned
in class to a problem of your interest.
This will involve a short report on a problem in geophysics. A good project will consist of about 10 pages
of text (double spaced) and 35 figures.
There are two types of projects:
(1) One type
of project will be to write a program to do a calculation. The manuscript should emphasize the
description of the equations and computational method used. The manuscript will
also describe how you tested the code and the predictions it makes.
(2) Another type of project
will be to use an existing program to infer something about a data set that you
or I have that is interesting to you.
The manuscript should include a brief description of the method,
emphasize the application, and show what you infer about structure.
All manuscripts should clearly communicate a good
understanding/insight of gravity, magnetics or heatflow,
and have the following ingredients A. Abstract (1 paragraph) B. Introduction C. Methods D. Results E. Conclusions Grading: 50%
homework; 30% class project; 20% class discussion
