ISBN P. THOSE of US who face the challenge of introducing physical oceanography to potential oceanographers, usually as seniors or frst-year graduate students, have for years felt the handicap of not having an appropriate text.
The elements important to an adequate introduction are I discussion of a very broad spectrum of subject matter, from the properties of seawater and how these can be altered internally and through boundary exchange, through the basic physical laws axiomatic to tluid motion and to energy and mass propagation in the tluid, to their application to the enormous range of time and space scales of phenomena encountered in the ocean, at 21 an appropriate intermediate level of physical and mathematical rigor.
Recently not one but two texts have appeared, each in its way definitely aimed at filling the void. University of British Columbia referred to as P and P. Knauss "attempts to introduce the student to the various subjects usually encompassed by the term physical oceanography. I have considered this point in my review. Both books appear to me to present the subject matter at exactly the right level of physical and mathematical rigor for the intended audience.
However, both also suffer from particular drawbacks, and I found that I was left, after a fairly careful perusal, with a curious sense of dissatisfaction. Both are very good books, each in its way. I will try to clarify my reasons for this as we proceed. In the first category, KNAt;SS is quite well set up with excellent graphs of the various properties of water and tables in Appendix 11 suitable for calculation.
P and P, on the other hand, includes no working tables, leaving the reader dependent on securing these source materials before attempting any calculations.
Curiously, the freezing point, so important to ocean physics in higher latitudes, is essentially ignored in both texts.
The subjects of stability, conservation equations and diffusion are well treated in both texts. The somewhat more descriptive subjects of radiation and heat, salt, and water balances, distributions of basic physical properties T, S in the ocean, and water mass characterization and T-S analysis, are less than completely developed for this audience. Heat budget, including discussion of the various Q terms, is good in KNAt:SS but the salt and water balance discussion is extremely sketchy.
