2018 Map of Ship Island

About this map

Ship Island serves as a critical barrier between the Mississippi Sound and the open Gulf, anchoring this portion of the Gulf Islands National Seashore. The island's geography is defined by narrow landforms like The Neck and local elevations such as Table Hill and Northwest Bluff. The surrounding waters are a complex network of maritime passages, including Ship Island Harbor, Ship Island Pass, and the Ship Island Bar Channel. Submerged features like Walker Shoal, Middle Ground, and Loggerhead Shoal illustrate the shifting sands that have historically challenged navigation in these waters. The southern portion of the sheet documents the maritime boundary between Harrison County, Mississippi and St. Bernard Parish, Louisiana, marking the jurisdictional divide in the coastal waters.
