سالینٹی (Salinity) refers to the concentration of salts in water, typically measured in parts per thousand (ppt). It is an important factor in determining the health of aquatic ecosystems, as different organisms thrive in varying salinity levels. For example, freshwater environments have low salinity, while marine environments, such as oceans, have high salinity. Salinity affects water density, which in turn influences ocean currents and climate patterns. Changes in salinity can result from natural processes, such as evaporation and precipitation, or human activities, like agriculture and industrial discharges. Monitoring salinity is crucial for managing water resources and protecting aquatic life.
