Florida Keys National Marine Sanctuary is home to a diverse community of underwater habitats, ranging from the only coral barrier reef in the continental United States to the largest documented contiguous seagrass community in the Northern Hemisphere. More than 6,000 animal species are found here, along with an array of submerged historical and cultural resources, making this one of the world's most cherished locations for diving, fishing, boating, and wildlife viewing.
A team of researchers from NOAA’s Mission: Iconic Reefs program and partners from Mote Marine Laboratory & Aquarium and the Coral Restoration Foundation completed a scientific mission February 14, 2024 to quantify the impact of 2023’s marine heat wave on corals in Florida Keys National Marine Sanctuary.
The spirit of Florida Keys National Marine Sanctuary is captured in a mosaic image by artist Matt McIntosh for a poster that commemorates the 50th anniversary of the sanctuary system.
The Office of National Marine Sanctuaries serves as the trustee for a network of underwater parks encompassing more than 620,000 square miles of marine and Great Lakes waters from Washington state to the Florida Keys, and from Lake Huron to American Samoa. The network includes a system of 15 national marine sanctuaries and Papahānaumokuākea and Rose Atoll marine national monuments.
