This book presents an in-depth discussion of the biological and ecological geography of the oceans. It synthesizes locally restricted studies of the ocean to generate a global geography of the vast marine world.
Based on patterns of algal ecology, the book divides the ocean into four primary compartments, which are then subdivided into secondary compartments.
*Includes color insert of the latest in satellite imagery showing the world's oceans, their similarities and differences
*Revised and updated to reflect the latest in oceanographic research
*Ideal for anyone interested in understanding ocean ecology -- accessible and informative

After 4 years of war service and after graduating from the University of London in 1952, Alan Longhurst subsequently studied the ecology of benthic communities and demersal fish off tropical West Africa and New Zealand, and the ecology of oceanic zooplankton in the eastern tropical Pacific, the north Atlantic and the arctic archipelago of Canada. He has held both research and administrative posts in several laboratories and has had many less formal occupations, such as coordinating the EASTROPAC surveys or acting as Secretary, SCOR. He has published widely in the field of benthic and pelagic ecology, and concerning the ecological basis of fisheries. He is now retired and spends much of year in SW France, where he assists his wife in running a gallery of contemporary art, keeping a sharp eye out for oceanographers among their clients.
