evaporation
What causes low salinity in the oceans at high latitudes?In subtropical latitudes, high surface evaporation creates high salinity near the sea surface. In subpolar latitudes, high precipitation creates low salinity near the sea surface. As these waters flow into the ocean interior, they create layers of high and low salinity.
Salinity in oceans decrease when near a river because the river adds fresh water, which lowers the percentage of salt in the water, causing the salinity to decrease.
The annual mean ocean surface salinity typically ranges from about 30 to 37 practical salinity units (PSU). This variation is influenced by factors such as evaporation, precipitation, river runoff, and ocean circulation. Regions near the equator often have lower salinity due to high rainfall, while areas in subtropical regions can have higher salinity due to increased evaporation.
Areas near the poles like the Arctic Ocean will have the lowest salinity
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.
Yes, in regions of heavy precipitation, the increased input of fresh water from rainfall can dilute the salinity of surface waters. This can occur in coastal areas and near river mouths where freshwater runoff mixes with the ocean water, reducing the overall salinity of the surface waters in those areas.
Well, Salinity is the measure of dissolved salts and in the ocean they're already there , ( not artificial) but near a warm tropical ocean or really anywhere where there is no more water coming in, then its fine. Hope I helped

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.
about 95% of ocean life exists near the surface. about 95% of ocean life exists near the surface.
near the desert(30 degrese latitude) more water is evaporated than returned to the ocean by rainfall or rivers\canals.thereforth the ocean salinity near the deserts would be higher than most other latitudes
rain, snow, and melting ice add fresh water to the ocean, lowering the salinity there. Salinity is also lower near the mouths of large rivers. These rivers empty great amounts of fresh water into the ocean.
