Study Notes
Ocean Salinity
- Evaporation of water contributes significantly to ocean salinity by leaving salts behind, thus increasing concentration.
- A commonly used unit to express salinity is practical salinity units (PSU), which reflect the total dissolved salts in seawater.
Factors Affecting Salinity
- Precipitation does NOT increase ocean salinity; rather, it dilutes the salt concentration in seawater.
- Minor variations in ocean surface salinity can affect ocean circulation, marine ecosystems, and climate patterns.
Brackish Water
- Salinity values for brackish water typically range from 0.5 to 30 PSU, with the upper limit being around 10 PSU, indicating a mix of freshwater and seawater.
