In October-November, the decrease of the equatorial undercurrent at 85 m depth induces by the same way a vertical displacement of the 17 degree C isotherm of 16 m. Vertical mixing takes place during the two cooling periods; maxima and vertical shear are found for both years in June-July between 10 and 35 m depths and in October-November between 35 and 60 m depths.
