The salinty near the surface of the sea can be lowered in some locations by the inflow of fresh water from a large river or from the melting of sea ice or glaciers.
The lowest areas of salinity in an ocean are near where fresh water rivers empty into them. This is because the influx of fresh water creates an area of lower salinity compared to the remainder of the ocean.
Lower rates of evaporation so more water to dilute it.

Surface water slainity is higher in tropical regions.
yes come on people really.... think I'm 11 years old and i no that
hi
Areas near the poles like the Arctic Ocean will have the lowest salinity
Surface water salinity ranges from 32 to 37 parts per 1000
Surface water salinity ranges from 32 to 37 parts per 1000
Deep ocean currents and surface currents do meet, but mixing is limited. The waters stratify based on temperatures and salinity. The higher the salinity, the heavier the water.
The surface areas of the ocean have abundant nutrients.
Excessive freshwater (rain) flowing into a shallow sea can change the salinity.
