This text covers the traditional range of topics in regional oceanography. An important aspect of work is its novel approach to a description of the features which give each ocean region its character. The two core principles are the use of the most modern database for all maps of regional distributions of properties and a discussion of all observed features within a frame of reference developed from ocean dynamics, rather than based on the simple geographical approach. The ocean's role in climate variability and climate change is described in detail. The book also includes an evaluation of all major international research projects such as FGGE, IIOE and TOGA. The SI system is used throughout. The use of modern data and inclusion of the oceanographic literature up to 1992 and early 1993 make it a useful reference text.
