Drink a (small) glass of seawater and you will remember salinity.
Salinity
Salinization is the process by which a non saline soil becomes saline, as by the irrigation of land with brackish water, While desalination is the process to remove salts from seawater or soil. So the difference is that salinity is the concentration of salt in, for example water, desalination is the process of removing salts from the water.=P
Decreases with increasing temperature
The seawater does freeze. The freezing point of seawater depends upon it's salinity,which is the amount of salt that it contains. Open ocean seawater has a salinity of about 35. Fresh water freezes at 0 degrees Celsius and 35 water freezes at about -2 degrees C. The decrease is linear so that water with a salinity of 17 freezes at about -1 degree C. In the winter large tracts of polar seawater freeze to a considerable thickness.
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.
The average salinity of seawater is about 35 grams of dissolved salts per kilogram of seawater, or 3.5% by weight.
