Proceedings of the 1978 IEEE First Working Conference on Current Measurement, 2005
The dynamics of mixed layers and the variability of coastal current systems are two important problems that require the measurement of near-surface currents. Near the surface, the wave field generates currents of higher frequency than the current field of interest, leading to the requirements for a current meter which properly averages motion at ...
