Salinity events refer to changes in the concentration of salt in water bodies, such as oceans, rivers, and lakes. These changes can occur due to various factors, including evaporation, precipitation, river inflow, and human activities. High salinity can affect aquatic life, as many species have specific salinity ranges in which they can thrive. These events can be temporary or long-lasting, impacting ecosystems and water quality. For example, hypersaline conditions can lead to reduced biodiversity, while freshwater influx can dilute salt concentrations. Monitoring salinity is essential for managing fisheries and preserving habitats in affected areas.
