because of evaporation
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.

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

Because of evaporation, the infusion of freshwater is necessary to maintain the existing salinity percentage.
Oceans are big water bodies. Salinity is due to the presence of minerals in water.
The amount of salt in the water. Near the surface of the open oceans salinity is in general between 3.3% and 3.7%
salinity
It is the study of marine meteorology. It involves relating ocean processes to the effects it has on the weather and vice versa. For example how the warm oceans can affect weather or how rainfall can affect the salinity of the oceans. Basically it involves the study of atmosphere-ocean interactions.
There are several factors that affect salinity. Some of the main factors include evaporation and precipitation which will affect the salinity of oceans and seas.
3.1-3.6% salinity
The world's oceans have a salinity of about 3.5%
