REVIEW
Conference on Physical and Chemical Properties of Sea-Water, Easton, Maryland, September 4-5, 1958. National Academy of Sciences, National Research Council, 1959. Publication 600, 202 pp. The book gives a report of the Conference held in Easton, Maryland 4-5 September, 1958, at which 40 outstanding American scientists met to discuss some of the requirements for observing and interpreting the physical and chemical properties of sea-water. Three committees were appointed to draft recommendations and suggestions for future work: a Committee on Field Measurements, a Committee on Chemical Properties, and a Committee on Physical Properties. As a focus for the discussions, 17 papers covering the different fields on chemical and physical oceanography were read. The book first gives the reports from the three committees, and then the 17 papers, each of which is followed by a summary of the discus~on. About one third of the book deals with physical oceanography, discussing: The classical hydrographic procedure, geostrophic currents, adiabatic temperature gradient and thermodynamics of sea-water. The next part deals with chemical oceanography: The chlorinity-density relationship and the problem of the variations of the relative proportions of the major constituents of sea-water, assessment of the accuracy and precision of data, and the possible role of biological processes in the composition of sea-water. A third part describes analytical techniques and various new apparatuses which arc, or can be, developed for the determination of the salinity or density of sea-water. I can recommend this book as being of great value to all working oceanographers. It gives a picture of the present situation stating what is known and unknown in physical and chemical oceanography, and pointing out ways to be followed in the future. It is an incentive to reconsider these problems and to discuss their solution. The book is printed in rota-print and is unbound. However, good figures and many references make this book attractive and very useful to all who are working in this field. E. FOYN
