"How do the oceans work?" Essentials of Oceanography, Eleventh Edition, takes an interdisciplinary approach to help readers answer this question. The latest edition brings together the interrelated spheres that compose Earth's systems as they relate to the oceans: geological, chemical, physical, and biological. Trujillo and Thurman balance rigor and accessibility, combining in-depth discussions of oceanographic concepts with highly visual and interactive features to demystify the subject for the non-scientist. This unique combination has made Essentials of Oceanography the best-selling brief book-and one of the best-sellers overall-in oceanography.
