Intercomparison of current measuring technology for coastal dispersion problems

Measurements which were taken to provide data for the validation of numerical models to simulate dispersion in the coastal zone are discussed. Results of currents in a near-shore region measured by HF ocean surface current radar, moored current meters, shipborne acoustic Doppler profilers, and drifting drogues are discussed. Each instrument provides measurements that are useful in the development of numerical models to simulate the tidal-, wind-, and density-driven circulations. In general all of these instruments are reliable and accurate. Specific applications for which each is most appropriate are identified
