2020 Map of Mississippi Sound (All Water)

About this map

The Mississippi Sound dominates this coastal survey, serving as a critical maritime corridor for both commercial and recreational transit. The deep-water Gulfport Channel cuts through the sound, providing essential access for vessels moving toward the mainland, while the east-west Intracoastal Waterway facilitates protected transit along the Gulf Coast. In the southeastern corner, the protected boundary of the Gulf Islands National Seashore appears, marking a transition from open water to preserved coastal environments. This map focuses primarily on the hydrography and navigational infrastructure of the sound, including a designated Ferry route, illustrating the vital role these waters play in the regional economy and connectivity of the Harrison County coastline.
