As oceanography has matured, the previously separate interests of chemical, biological and physical oceanographers have converged. This set consists of two volumes that reflect the change in attitude in oceanography to a solid interdisciplinary approach. Volume 10, Processes a nd Methods , and volume 11, Regional Studies and Syntheses , present a systematic and integrated treatment of coastal oceanography. They deal with many of those aspects of oceanography that most impact human activity: biological productivity and fisheries, currents and shipping, tidal behaviour, sediments and silting, waves and air/sea interactions.
