2024 Map of Mississippi Sound (All Water)

About this map

The Mississippi Sound defines this maritime landscape, serving as a critical transitional environment between the mainland and the open Gulf of Mexico. This survey highlights the coastal management and maritime infrastructure essential to the Mississippi coast, including the well-defined Intracostal Waterway and the Gulfport Channel, which facilitate regional shipping and navigation. In the southeastern corner, the map shows a portion of the Gulf Islands National Seashore, reflecting the preservation of the barrier island ecosystem. As an all-water quadrangle, the focus remains entirely on the hydrographic features and federally protected waters that characterize this stretch of Harrison County.
