No. In fact, in semi-isolated lagoons, evaporation actually increases salinity. Evaportation, in this case, means that water is leaving the ocean in the form of water vapor. The salt is left behind.
After distillation of sea water drinking water is obtained.
precipitation
runoff from land
Melting of sea ice
one event to research for this is el nino.
formation of sea ice
evaporation
The density of seawater increases if salinity increases.
Conductivity can be used to calculate the salinity of the water.
The average salinity of seawater is 35 parts per thousand (or ppt).
Relative salinity is the most important factor in seawater density.
Seawater's density varies by temperature and salinity. I.e., cold water is more dense than warm water, and water with a higher salinity (more dissolved salt) is less dense than water with a lower salinity.
evaporation
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.
Ice has zero salinity. When it is frozen, the salt is pushed out. Therefore, since the salinity of normal seawater is about 35 ppt, it has 35 ppt more salinity than seawater.
The density of seawater increases if salinity increases.
Storms at sea. The evaporated water falls back into the ocean with no net effect on salinity.
Conductivity can be used to calculate the salinity of the water.

Drink a (small) glass of seawater and you will remember salinity.
