ESSENTIALS OF OCEANOGRAPHY provides a basic understanding of the complexities and uncertainties involved in ocean use and the importance of oceans in nurturing and sustaining life. Streamlined to remove nonessential technical details so students can focus on the content without interruptions to the narrative, the 8th Edition's slimmer table of contents allows instructors to cover one chapter a week -- while leaving some extra time in the semester. Using exclusive content from the National Geographic Society, ESSENTIALS OF OCEANOGRAPHY, 8th Edition, illustrates the complexity and beauty of the ocean while making it more accessible to a wider range of students. With this book, bestselling authors Tom Garrison and Robert Ellis illustrate the interdisciplinary nature of marine science and give students the most dynamic and current introduction to oceanography available today.
