The Marquesas Keys anchor the northeastern corner of this maritime landscape, where the shallow waters of the Gulf of America meet the deep currents of the Straits of Florida. This specific quadrant reveals a complex system of submerged hazards and migratory shoals that have long challenged navigators in the Florida Keys. Notable seafloor features include Isaac Shoal, Halfmoon Shoal, and the shifting sediment of The Quicksands.
