MonitoringLocationDescriptionText Horn Island is one of the islands comprising the barrier island chain off the Mississippi Coast. The island extends roughly 14 miles (22 km) from Dog Keys Pass at its western extremity to Horn Island Pass at its eastern end. From the coastline south of Ocean Springs, the island lies 7 miles (11 km) offshore in Mississippi Sound, separating the waters of the Sound from the Gulf of Mexico. At its widest point, the island is 1 mile (1.6 km) across; it measures less than a tenth of a mile across (0.16 km) at its narrowest point. Representative seagrass beds were chosen along the western end of Horn Island where the presence of seagrass beds was observed.
