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 amount of salinity in the water and high temperatures
If the salinity of surface ocean water is high in a particular place, it suggests that there is high evaporation rates in that area. As water evaporates, it leaves behind salt, increasing the salinity of the remaining water.
The salinity of ocean water is primarily due to high concentrations of dissolved salts, such as sodium and chloride. Other substances like magnesium, calcium, and sulfate also contribute to the overall salinity of the oceans. Processes like evaporation, precipitation, and volcanic activity can influence the salinity levels in different regions of the ocean.
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
You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
There are several factors that the Red Sea has high salinity. The Red Sea has a high rate of evaporation and very little precipitation. It also has a limited connection with the Indian Ocean, which has lower water salinity. The Red Sea has a lack of significant rivers or streams draining into the sea.
