| Summary |
Opening with a discussion of the earth's formation, hot spots, ridges, plate tectonics, submarine trenches, and cold seeps, this text goes on to address such topics as the role of oceans in the origin of life, tidal bore, thermal effects, ecosystem services, marine creatures, and nutraceutical and pharmaceutical resources |
