Description

On the Nature of Continental Shelves discusses continental margins using techniques of systems analysis applied on minicomputers. The book describes insights and theories of mechanisms of enhanced primary production at the continental shelves, emphasizing these as the source energy, food, and recreation, and a possible means to detect global change while in its early phases. The text explains circulation, equations of motion, Ekman dynamics, and baroclinic effects of vertical changes in water density. Production in the seas involves the process of photosynthesis by organisms in which instruments on aircraft platforms can measure salinity and chlorophyll fluorescence. During photosynthesis, some of the light energy absorbed by phytoplankton pigments is emitted as fluorescence, at longer wavelengths, which can then detected. Adult fish and crustaceans are mobile and add a biological vector to the physical movement of organisms on the continental shelves. The book examines food limitation and the conditions of the Bering Sea, the Mid-Atlantic, and the Gulf of Mexico. The text also investigates sinking losses, present depocenters, atmospheric forcing, eutrophication, overfishing, and the effects of climate on primary production at the continental shelves. The book can be beneficial for students of meteorology, oceanography as well as to marine ecologists, biologists, and environmentalists.
