About this map

Marquesas Keys anchor the eastern edge of this maritime chart, where the Gulf of Mexico meets the Atlantic Ocean at the Straits of Florida. This 2024 survey documents a critical intersection of protected environments and underwater hazards west of the main Florida Keys. The landscape is defined by extensive shallow-water features such as The Quicksands and numerous shoals, including Rebecca Shoal, Halfmoon Shoal, and Isaac Shoal, which have long dictated maritime navigation in these waters.

Conservation boundaries dominate the emergent landmasses, with the Key West National Wildlife Refuge and the Florida Keys Wilderness protecting small outposts like Mooney Harbor Key and the Gull Keys. The map illustrates the shifting nature of this environment, notably at New Ground and the Rebecca Shoal Channel, providing a contemporary record of the seabed and islands that form this southernmost reach of the United States.
