The Stability of the Shallow Sound Channel in the Eastern North Atlantic.

Abstract

West of Gibraltar the SOFAR sound channel is split by the outflow of water through the Strait. Measurements confirm that the geographical extent of the shallower of the two subchannels is related to the extent of the higher-salinity outflow near 1000 m depth. Other data indicate that there is only a modest degree of variability in the parameters of the shallow sound channel over relatively large horizontal scales. The magnitude and stability of the shallow sound channel, which is found to extend across the western approaches of Europe, recommends it for further study by acousticians and for use by oceanographers in tracking current floats.
