2018 Map of Marquesas Keys West

About this map

The western edges of the Marquesas atoll are charted in this marine survey, capturing the complex shoals and shifting sands of the lower Florida Keys before they drop into the deep Straits of Florida. This maritime landscape is defined by its shallow navigation hazards, featuring the aptly named The Quicksands and the broad expanse of New Ground. In the eastern portion of the sheet, the land emerges at Mooney Harbor Key and the small Gull Keys, which frame the protected waters of Mooney Harbor. To the west, the seafloor rises at Rebecca Shoal and Isaac Shoal, separated from the main banks by the deep Rebecca Shoal Channel. The survey provides a clear view of the coral and sand formations that have historically challenged navigators traveling between the Atlantic Ocean and the Gulf.
