Factors Affecting Ocean Salinity

Ocean salinity refers to the concentration of dissolved salts in seawater. It is typically measured in parts per thousand (ppt) or practical salinity units (psu). Ocean water contains a variety of dissolved inorganic salts, with sodium chloride (table salt) being the most abundant. Other common salts found in seawater include magnesium, calcium, potassium, and sulfate ions.

Major Factors

Evaporation: The salinity of surface ocean water is primarily influenced by the rate of evaporation. Higher evaporation rates result in greater salinity. For example, the Mediterranean Sea, with its high evaporation, has higher salinity levels.
