The factors affecting oceanic salinity are as follows:
1. Evaporation.
2. Water availability through rainfall.
3. Arrival of river water.
4. Prevailing winds.
5. Oceanic currents.
6. Transmission of oceanic water.
The increase or decrease in the amount of evaporation affects oceanic salinity. The more the availability of rain water, the less is the salinity. Salinity is more when less pure water comes into the ocean. Likewise, the more or less amount of river water joining the sea is a salinity controller. In the same way, the conditions of prevailing winds and oceanic currents play an important role in increasing or decreasing the salinity. Transmission occurring in oceanic water plays an important role in determining the salinity.
