Basic Physical Concepts

At high latitudes, two features of geophysical fluid dynamics are particularly apparent: first, the impact of rotation is stronger near the poles than elsewhere; and second, the combination of cold temperature and salt injection inherent in the freezing process produces very dense water, so that the polar and subpolar regions provide the main conduit by which the abyssal ocean communicates with the remainder of the climate system. A cursory review of some basic physical properties of ocean dynamics particularly relevant to the IOBL is presented in this chapter. More rigorous treatment may be found in standard geophysical fluid dynamics textbooks (e.g., Gill 1982; Pedlosky 1987).
