An elegant presentation of how the ocean works. Denny's purpose is to review a selection of oceanographic topics to provide a background for considering such current public issues as climate change and marine fisheries. Accessible and enjoyable reading, and the scholarship is very sound."--Nicholas D. Holland, University of California, San Diego"A well-written, coherent, interesting introductory text for teaching oceanography. The vast majority of the books on the market are full of glitz and relatively little else, and there is a great need for a book of this type."--Carol Arnosti, University of North Carolina, Chapel Hill
