Extreme residual current speeds upon the uk continental shelf

Knowledge of the extremes of residual currents (ie, the underlying current which remains when tidal currents have been removed) is extremely sparse, and mostly fortuitous. During the North Sea storm surge of 1953, for instance, the residual currents at the Varne Lightvessel in the Straits of Dover averaged an unusually high level over a full lunar day, but due to the method of recording there is no means of obtaining the peak current speed, which is likely to have been notably greater.
