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).
Anyone who has ever tasted seawater knows that it is truly salty. The salty residue left on swimsuits after theyve been in the ocean is further evidence of the oceans salinity. Salinity is a measure of how much salt is dissolved in water.The average salinity of seawater for all Earths oceans is about 35 grams of dissolved salts per kilogram of seawater. This is shown as 35 parts per thousand, or 35.he salty residue left on swimsuits after theyve been in the ocean is further evidence of the oceans salinity.
