SALINITY OVERVIEW Salinity is the concentration of dissolved salts in water, usually expressed in parts per thousand (ppt). Objects float higher in salt water than fresh water because salt water is denser (heavier per unit of volume).
Salinity is the presence of salt in the land surface, in soil or rocks, or dissolved in. water in our rivers or groundwater. There is salt in many parts of the Australian landscape. When wind and rain weather rocks that contain. salt, or carry salt from the ocean, then salt is left in the landscape.
