Extreme Flooding Events in Coastal Lagoons: Seawater Parameters and Rainfall over A Six-Year Period in the Mar Menor (SE Spain)

Climate change is one of the main problems currently strongly conditioning ecosystems all over world. Coastal lagoons are amongst most vulnerable habitats, and they undergoing extensive human impact due to their high production rates close proximity urban agricultural centers. The Mar Menor, largest saltwater lagoon in Europe, an example a highly impacted ecosystem. In December 2016 September 2019, climate change-induced DANA (upper-level isolated atmospheric depression) flooding events took place there, temporarily altering oceanographic properties. Data gathered throughout (11 stations inside 1 outside lagoon) from 2021 were analyzed order assess variability seawater parameters: salinity, density, chlorophyll-a, turbidity, dissolved oxygen, events. Results showed parameters that reestablished at different rates, 4 10 months respectively, following description environmental conditions effects have been reported after extreme rainfall lagoon. amount correlated with changes parameters, such as increase turbidity chlorophyll-a values. Furthermore, oxygen saturation, while density salinity. Such weather worsened by change, growing more frequent between shorter intervals time. decelerate ecosystem decline, comprehensive management plans needed address various factors might add anthropic impacts natural environments.
