Well, Salinity is the measure of dissolved salts and in the ocean they're already there , ( not artificial) but near a warm tropical ocean or really anywhere where there is no more water coming in, then its fine. Hope I helped
rainfall decreases salinity near the surface, while evaporation increases the salinity, in most warm and dry places. Below the surface zone, the salinity remains fairly constant throughout the water columns. :)

Addition of more fresh water.
thermohaline
the amount of salinity in the water and high temperatures
Ocean currents are generated by several environmental factors. These include wind, salinity variations, gravity, and natural events such as earthquakes.
False.
38 parts per thousand
salt a decrease in temperature and an increasue in salinity
Temperature, density, and salinity of water
Salinity can vary because of water temperature, rivers emptying into the ocean and mixing with ocean water, ice forming or melting, evaporation and precipitation. I think temperature is the biggest reason.http://wiki.answers.com/List_the_reasons_for_variations_in_salinity_in_the_various_oceans#ixzz16sZMdZIZ
Salinity is the saltiness or dissolved salt content of a body of water.The average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt.
The open ocean of any depth, where animals swim or float freely is called a pelagic zone. Salinity variations in the open ocean normally ranges from 33 to 38 percent.
Sinking of dense, cold water with high salinity :)
