*Appendix A.6. Salinity Patterns*

The general patterns of salinity in the lagoon of La Carbonera are seen in Figure A5. During a tidal cycle, these patterns are very dynamic [33]. At high and low tides the estuarine, marine, and hiperhaline zones move, due to the influence of the tides and dominant winds, as well as the inflow from the underground spring, which can increase or decrease the salinity in the lagoon. At the highest tide level, and under the effects of strong winds, the seawater can move further into the hiperhaline zone. At low tide, brackish water can reach the mouth of the lagoon [33].
