salinity salinity
No sea exists. The Caspian Sea has a salinity of approximately 1.2%, about a third the salinity of most seawater.
The Red Sea receives little rain fall and has high evaporation rates resulting in high-salinity water. The Baltic Sea contains low-salinity water as a result of abundant freshwater runoff from the surrounding land.
The salinity of the Red Sea ranges from 3.6 to 3.8%.
The amount of salinity that there is in the sunlight zone is about 3.5 percent. About 90 percent of sea life also resides in this zone.
The average ocean or sea has a salinity of about 3.5%. In metric, about 35 grams per liter.
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.
Saltwater does not have one definite salinity - for instance the salinity of the water in the Dead Sea is different to that of the Atlantic. Indeed the salinity of the sea itself can vary.
Partial answer: The salinity of the dead sea is ~31.5% by weight while the salinity of the Mediterranean is ~3.5%
