Fig. 5.9. Time series of longitudinal current velocity (m S-I) and salinity (psu) profiles obtained during PLATES I, II and III
flow of freshwater is reversed by the SW wind (10-14 m S-I) and 17 h later the section is
vertically homogeneous. A weak stratification develops as the flow turns towards the
sea. It holds until 65 h later, when a highly stratified (salt wedge) water column is formed.
