In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.

Salinity in the ocean is highest in regions where evaporation is high and precipitation is low. Density in seawater is determined by both temperature and salinity.

The open ocean of any depth, where animals swim or float freely is called a pelagic zone. Salinity variations in the open ocean normally ranges from 33 to 38 percent.
Cold and High Salinity k12 question.
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.
Because of the high discharge of freshwater
33 to 37 grams of salt per kilogram of seawater
Arctic ocean
The salinity of ocean water depends on its location, rate of evaporation, amount of precipitation and amount of freshwater added to the ocean.
