When evaporation occurs at a rate faster than precipitation, the net result is that salt is left behind and the salinity in the oceans will increase. Of course, new salt is brought into the ocean by rivers and deposition of salts on the sea floor takes salt out of the ocean. As a whole, the salinity of the ocean (total salt everywhere) has not changed for millions of years since these input and removal processes are in balance. The increased "saltiness" created by the imbalance between precipitation and evaporation in certain areas of the ocean (some very large) is balance by areas that are fresher so the whole ocean is not getting saltier.
It increases when the climate is warm. It does so because the sun evaporates the water and leaves all the salt behind, increasing the salinity. It makes the salinity above average
Increasing the salinity the density is also increased.

Increasing the salinity the density is also increased.
Evaporation leaves salt behind. So as ocean water decreases, the percentage of salt increases, increasing salinity. As evaporation increases, rainfall also increases, thus it decreasing the salinity of ocean water.
Increasing the salinity the density is also increased.
Arctic ocean
You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
salinity
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.
salinity
The lowest areas of salinity in an ocean are near where fresh water rivers empty into them. This is because the influx of fresh water creates an area of lower salinity compared to the remainder of the ocean.
An increase in ocean salinity can increase density creating a convection current.
Salinity is due principally to sodium chloride.
