Study Guide Endless Voyage Telecourse for Garrisons Oceanography: An Invitation to Marine Science, 7th by Tom S. Garrison Highly Recommend This Study Guide This Study Guide accompanies the Endless Voyage telecourse. Tom Garrison is a writer and science advisor for The Endless Voyage telecourse series. I bought this book as a suppliment to the required Oceanography textbook and DVDs. Little did I know that the Professor would "borrow" many of the midterm and final exam questions from the study guide. I'm sure that it helped me get an A in the class, as I was able to understand areas where I had weakness in understanding.
