Which consequence results when storms breach a barrier island?

💡 Explanation

Increased salinity occurs because inundation allows saltwater past the barrier eroding the freshwater/saltwater balance; the mechanism is saline intrusion. Seagrass decrease occurs therefore, rather than aquifer recharge, as saltier upper layers reduce density gradients.
