Significance of Ocean Salinity
- The freshwater flow from rivers affects the surface salinity in coastal areas.
- Ice freezing and melting impact the Polar area's surface salinity.
- The movement of water by the wind to other locations also impacts an area's salinity.
- Ocean currents cause fluctuations in salinity.
- The salinity of water in a region is affected by changes in temperature or density.
What is ocean salinity?
Dissolved mineral salts are present in all naturally occurring streams, including ocean water and rainfall. Salinity is a measure of how much salt is dissolved in saltwater.
- It is calculated as the amount of salt (in gm) dissolved in 1,000 gm, or one kilogram, of seawater.
- Usually, it is expressed in ppt or o/oo, or parts per thousand.
- One essential quality of seawater is its saltiness.
