Résumé

A critical examination has been made of four repeat surveys, covering a period of three years, in an area which is of vital importance to the safety of navigation by deep draught shipping. Replotting of the bathymetry from ship’s echo traces at a large scale has been rigidly controlled by Hifix. Large symmetrical and asymmetrical sandwaves have been found with amplitudes of up to 16 metres and wave lengths of up to 270 metres with a fairly high degree of stability over the three year period.
