Course-Format:

The normal week will consist of 2 lectures (M,W) and one group learning session on Friday. There are text chapters in addition to a few classic journal articles to accompany the lectures. There will be seven short problem sets due on Wednesdays. The group learning sessions on Friday will consist of a problem solving session in which students will discuss among themselves the problems like those due the next week.

There will be three tests.

Text:

Lectures follow the first 7 chapters of the new book: Chemical Oceanography and the Carbon Cycle (Emerson and Hedges). This is required reading and the book is available in the University Book Store.

Library Reserve:

Copies of other texts that cover much of the material covered in this class are on reserve in the Fisheries and Oceanography Library.

Web:

Lecture material in addition to that in the book, problems and problem solutions will be placed on the web site for the class.

Grades:

Problems: 40%

Tests: 50%

Class Participation 10%
