Open Source Textbook

Want to contribute? Many of you who are using this material in your classes can write web pages better than I, or you may want to include important new material. Here's your opportunity. I would like to make the textbook an open source document open to contributions from all. If you write a section, I will add it to the book and put your name on the contribution. Contact me at stewart@ocean.tamu.edu for more information.


Funding for this book comes partly from the State of Texas who pay my salary as a professor of oceanography at Texas A&M University, and partly from contract 1205046 with U.S. National Aeronautics and Space Administration's Jet Propulsion Laboratory which funds the production of educational material. This is their gift to the students and citizens of the world.
