How permanent does stratification caused by differences in salinity appear to be

Answer 1

Stratification caused by differences in salinity can potentially be quite permanent, especially in areas with strong haloclines where distinct layers of different salinity levels form and are slow to mix. In some cases, these layers can persist for extended periods of time, leading to long-term stratification. However, factors such as mixing due to wind or currents, seasonal changes, or influxes of freshwater or saltwater from rivers or other sources can disrupt this stratification and result in changes in the salinity levels of different layers. Overall, the permanence of stratification caused by differences in salinity can vary depending on the specific conditions and processes at play in a given water body.
