Essentials of OceanographyRevised for increased readability and streamlined for clarity, this text is designed to accompany an introductory college-level course in oceanography. This insightful, ecologically sensitive presentation of the relationship of scientific principles to ocean phenomena is made even more relevant to a new generation of teachers and students by pairing new co-author Alan Trujillo with renowned author Harold V. Thurman. *NEW - A new coauthor: - With Thurman's retirement from teaching, Alan Trujillo of Palomar College has been added as co-author for this edition.

The historical perspective is now included as chapter-opening feature boxes which highlight important events in oceanographic history relevant to chapter-specific material. - New placement of the chapter on plate tectonics (switched with the chapter on sea floor features) ensures that the processes of plate tectonics can be |
