Students will receive an extended description of the chemical properties of marine
systems and pertinent chemical processes operating
in the ocean.  The chemical interactions of seawater with sediments, the atmosphere
and the biosphere will be discussed.  Students are
expected to have had knowledge in general chemistry and oceanography, and high
motivation in learning.  Students will be evaluated with 
one midterm exam, one final exam, and a series of homework problems.

It is the student's responsibility to be familiar with the University of Georgia's
policy on academic honesty as published in the booklet 
"A Culture of Honesty:  Policies and Procedures of Academic Honesty".  Evidence of
academic dishonesty will be turned over to the Office
of the Vice President for Academic Affairs for consideration and possible action. 
The minimum penlty for a student found guilty of 
academic dishonesty is a grade of "F" in the course and a note on the student's
transcript.  There have been several recent changes in the
academic honesty policy at UGA.  This information is available on-line at
[http://www.uga.edu/~vpaa].  Click on the UGA Academic
Honesty Policy statement.
