Freshwater has a salinity of .005 percent or less.
The salinity of the ocean was much higher than I thought it would be.
marine
The salinity varies latitudinally. It's somewhere between about 3 and 5%.
freshwater
There is 3.5% salinity of salt in one gallon of ocean water. Now you divide that by 16, which is 0.21875. So there is 0.21875% salinity of salt in one cup of ocean water. Mathematics can really pay off!!! Good for you if you were interested in the salinity of salt in one cup of ocean water!!!:) :) :) :) :) :) :) :) :) :)
Arctic ocean
You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
salinity
Hypersaline refers to a body of water that has about 40 parts per mil salinity which is much higher than the salinity for average ocean water which is about 35 parts per mil salinity.
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.
