Essentials of OceanographyRevised for increased readability, this full-colour text offers an insightful, ecologically-sensitive presentation of the relationship of scientific principles to ocean phenomena. Now better suited for non-major oceanography courses, this edition offers a broader study with a marked reduction in concentrated topic coverage, with a continued emphasis on how we must take more precautions in activities that can modify the environment and learn how to keep these modifications to a minimum. |
