Sea is one of twenty-five volumes in the Life Nature Library. Published by Time-Life books in the 1960s, this series portrays the many aspects of the natural world. Despite its age, The Sea is a good, basic introduction to oceanography. Topics covered include the history of oceanography, the sea floor, waves, tides, currents, life in the sea, and how humans have used and will likely use the sea for food, energy, and minerals. As with other books in this series, there are many illustrations which supplement the reading. The chapter on sharks was especially fascinating. An appendix of important dates in ocean exploration is included. If you want a highly readable, non-technical book on the ocean then this book is for you.
