Introductory Oceanography approaches marine biology from an ecological perspective rather than a taxonomic one. This popular, straightforward, and comprehensive introduction emphasizes changes in the marine environment as a result of human activities, including sections of the Law of the Sea, petroleum and mineral resources, fisheries, and mariculture. Integrates environmental concerns, including, global warming, the depletion of the ozone layer, and marine productivity into relevant oceanography topics. Assesses the problem of marine pollution, including specific hazards such as plastics, petroleum, sewage, radioactive waste, halogenated hydrocarbons, and mercury. Issues include “Global Warming and Sea Level Rise” , “Beaches or The Dynamic Coastal Environment,” “Sharks,” and “Illegal Ballast Water and Exotic Species.” Ideal as an introduction to Oceanography.
