<u>Answer</u>:
The high sea surface salinity can be observed in the Pacific Ocean, the Indian Ocean, the Arabic ocean and the Mediterranean sea.
<u>Explanation</u>:
Due to rainfall and evaporation of water from sea the density varies with varying salts and minerals concentration that aggregate at the surface. The salinity in the seawater varies according to the amount of evaporation from a particular area.
Low salinity water is found in polar and subpolar regions that are near to the equator. Regions of high salinity are observed in the seawater which is centered around 30 degrees north and 30 degrees south to the equator due to the excess evaporation in these areas.
