Ocean Salinity refers to the proportion of salt in the ocean water. On an average, it is 35 parts per thousand.

Factor Affecting Salinity:

1Evaporation → Proofs the evaporation, higher the salinity.
2Cloud Precipitation → Greater the precipitation, lower the salinity.
3Ice Formation → High degree of ice formation increases salinity. And high melting of ice decreases salinity. eg: low salinity in Baltic sea, North Sea etc
4Ocean Current → They are responsible for balancing salinity across the oceans.
5Surrounding Land → Buffer of fresh rivers cause decrease in salinity of ocean.
6Other Factor → Meteorite input, or underwater vulcanism might increase salinity of ocean.

Salinity has multidimensional impact:

1Ocean Temperature regulation of affecting flow of Ocean current
2Fisherie → Highly saline water does not allow fish to survive. eg: Dead Sea.
3Coral also cannot survive in high salinity conditions.
4Salinity determine density — which affect the ease of navigation for ship, as per Archimedes principle.
5High saline water is much expensive for desalizing for drinking purpose.
6Increased salinity destroy coastal biodiversity ecosystem such as mangroves & delta etc

Thus, salinity is a salient feature of ocean which affect both marine and human lives.
