Measuring and Analysing the directional spectrum of ocean waves

Part I covers the theory of directional spectra of ocean waves, the methods and instruments to measure it, techniques for the statistical intercomparison of directional wave data, and spectral wave modelling. The technical editor for Part I was H. E. Krogstad, who has also written much of it. Part II, with J. Monbaliu as the technical editor, covers intercomparison studies between the various types of wave measurement techniques.
