Contaminants from the Channel flow through the Dover Strait into the North Sea where they represent a significant fraction of the enhanced concentrations observed along the continental coast. Despite numerous previous investigations, the magnitude of this net flow and its dependency on various forcing factors remain uncertain. The new UK H.F. Radar system, OSCR (Ocean Surface Current Radar) developed for measuring nearshore surface currents offers a clear opportunity of establishing the magnitude and nature of this flow. Starting in July 1990, H.F. Radar observations were made in the Dover Strait for five months from the French coast overlapping (for two months) with five months from the English coast. These measurements involved fully-automised monitoring... |
