Saltwater, comprising approximately 3.5% salt and 96% water, contains essential minerals like sodium, magnesium, calcium, potassium, chloride, and sulfate. Salinity varies based on geographical factors, being influenced by freshwater runoff, evaporation, and precipitation. Areas near river mouths exhibit low salinity, while subtropical regions, where evaporation exceeds precipitation, showcase higher salinities. Understanding salinity is crucial as the minerals dissolved in seawater play a vital role in marine organisms' health and ecosystem balance.

  2. SALTWATER!!!

  3. Salt Water!!! • Salt present in sea water is in its ionic form!!! • Sodium, magnesium, Calcium , Potassium, Chloride, sulfate

  4. Sea Water • Approx.. 3.5% salt and 96% water. • Table salt is most common salt present • Salinity of surface water varies with latitude and topographical features of the earth. • Evaporation, precipitation, freezing, thawing, and fresh water run off.

  5. Salinity is the measure of concentration of dissolved inorganic salts in the water For short: The ratio of water to salt. Salinity! • Parts of ocean that are close to river mouths (Freshwater). Low salinity • Water in subtropical areas where evaporation is high and precipitation is low have high surface salinities. • When water evaporates it leaves behind salt causing higher salinity.

  6. Salinity Continued. • Near the equator where rain falls heavy, surface water has lower salinity. • 30 degrees north and south of the equator have a pattern of evaporation exceeding precipitation. • These areas have higher salinity!

  7. Importance of Salt! • The minerals in the seawater are important to marine organisms. • Even small amounts are concentrated in an organism’s tissues.
