Marquesas Keys and the neighboring Gull Keys dominate the western reach of this maritime survey, marking a significant coral atoll formation in the lower Florida Keys. The landscape is defined by the shallow, protected waters of Mooney Harbor, which sits sheltered by the sweeping curve of the islands. To the east across the deep Boca Grande Channel lies the isolated Boca Grande Key, a solitary landmass surrounded by the open waters where the Gulf of America meets the Atlantic Ocean. The southern portion of the sheet is governed by the deep-water currents of the Straits of Florida, illustrating the transition from the shallow harbor environments to the primary shipping channels that have historically guided navigation through these carbonate banks.
