I am almost finished reading Oceanography: An Invitiation to Marine Science by Tom Garrison.
I have enjoyed this book. It is well written, and is packed full of useful information. Most text books have some information stuck in the middle of fluff, and this book has very little fluff, and yet is very readable. I got back in touch with my interest in underwater exploration by Remotely Operated Vechiles (ROV). Years ago, I met Robert Ballard, who found the Titanic at the bottom of the ocean, as part of a Gifted and Talented program.
Each chapter had a section on a scientist working in the field, who then explained the research that was their specialty. There were plenty of useful graphics and maps with units, great descriptions, and so on.
Thank you for reading my post.
