Where do you find low salinity sea water in the surface of the ocean? Low salinity water (light blue region at 10-150 north) lies in the polar and subpolar regions and near the equator.raw a picture of the intertropical convergence zone in your handou Moving poleward, another region of low sea surface salinity lies around 60o north and south of the equator, where once again precipitation is greater than evaporation, due to rising masses of air that produce heavy rainfall.
