●The time-series of vertical temperature differences at the base of the water column, recorded between two thermistors separated vertically by 1 m at the outermost thermistor chain station (Tc 4).
●The large vertical temperature gradients recorded between the 2 thermistors reached values as high as 9°C m-1 and occurred during the upwelling events.
●Often these huge gradients are followed by small temperature inversions of the order of -0.1°C. These temperature inversions seem to last for several hours during the initial phase of the upwelling event.
