About twenty years ago, The Dutch automatic measuring network at the North Sea was installed and has been extended since. To improve wave forecasting in the North Sea using various data assimilation techniques, a number of wave directional buoys was added later to the network. At present, seven so-called Wavec buoys are operational, two of them in the Northern part of the North Sea, the remaining five around the Dutch coast. A robust processing method described by A.J.Kuik et al. (1988) is used real-time for calculating wave directional spectra and related parameters. The spectra are available in a form which makes ,them particularly suitable for the application of data assimilation. For instance, A.C. Voorrips et al. (1997) have used directional data of this network in conjunction with their Optimal Interpolation of Partitions method applied to the present North Sea version of WAM which is used by the maritime meteorological service of KNMI. In this paper, the application of directional spectra from the Dutch measuring network will be reviewed, including a plea for more real-time exchange of wave spectra.
