Marquesas Keys and the surrounding waters of the Atlantic Ocean define this 2015 study of the lower Florida Keys. The map details the transition from the protected waters of Mooney Harbor to the deeper Boca Grande Channel. On the eastern edge of the sheet, Boca Grande Key sits isolated, while the small Gull Keys punctuate the shallow flats. A notable navigational feature is the Dry Tortugas Fry, which cuts a straight line across the marine landscape. The map provides a precise record of the shoreline and coastal geography in Monroe County during the early 21st century, illustrating the unique coral atoll structure of the Marquesas group.
