The analysis reveals that Pulley Ridge is connected with M. J. Olascoaga, [email protected] the North Atlantic, the Caribbean Sea, and most of the Gulf of Mexico. Preferred connecting pathways are identified and arrival times to potential reef sites computed. The study demonstrates the importance of Pulley Ridge as a source for neighboring regions like the Dry Tortugasa, the Florida Keys, Campeche Bank, Citation: and the east Florida coast as well as a self-recruitment area for species with short competence time. -

The ridge has been mapped using multibeam bathymetry, submarines and remotely operated vehicles, and a variety of geophysical tools. The ridge is a subtle feature about 5 km across with less than 10 m of relief. The shallowest parts of the ridge are about 60 m deep. Surprisingly at this depth, the southern portion of the ridge hosts an unusual variety of zooxanthellate scleractinian corals, green, red and brown macro algae, and typically shallow-water tropi- cal fishes. The corals Agaricia sp. and Leptoceris cucullata are most abundant, and are deeply pigmented in shades of tan-brown and blue-purple, respectively. These corals form plates up to 50 cm in diameter and account for up to 60% live coral cover at some localities. -
Anthropogenic Nutrient Enrichment of Seagrass and Coral Reef Communities in the Lower Florida Keys: Discrimination of Local Versus Regional Nitrogen Sources
Journal of Experimental Marine Biology and Ecology 308 (2004) 23–58 www.elsevier.com/locate/jembe Anthropogenic nutrient enrichment of seagrass and coral reef communities in the Lower Florida Keys: discrimination of local versus regional nitrogen sources Brian E. Lapointe*, Peter J. Barile, William R. Matzie Marine Nutrient Dynamics Program, Division of Marine Science, Harbor Branch Oceanographic Institution, Inc., 5600 US 1 North, Ft. Pierce, FL 34946, USA Received 22 August 2003; received in revised form 16 January 2004; accepted 28 January 2004 Abstract Land-based nutrient pollution represents a significant human threat to coral reefs globally. We examined this phenomenon in shallow seagrass and coral reef communities between the Content Keys (southern Florida Bay) and Looe Key (south of Big Pine Key) in the Lower Florida Keys by quantifying the role of physical forcing (rainfall, wind, tides) and water management on mainland South Florida to nutrient enrichment and blooms of phytoplankton, macroalgae, and seagrass epiphytes. Initial studies (Phase I) in 1996 involved daily water quality sampling (prior to, during, and following physical forcing events) at three stations (AJ, an inshore area directly impacted by sewage discharges; PR, a nearshore patch reef located inshore of Hawk Channel; and LK, an offshore bank reef at Looe Key) to assess the spatial and temporal patterns in advection of land-based nutrients to the + À À offshore reefs. Concentrations of dissolved inorganic nitrogen (DIN = NH4 +NO3 +NO2 ), soluble reactive phosphorus (SRP), and chlorophyll a increased at PR and LK following a wind event ( f 15 + knots, northeast) in mid-February. The highest DIN (mostly NH4) and SRP concentrations of the entire study occurred at the inshore AJ during an extreme low tide in March. -

Geology of Florida Local Abundance of Quartz Sand
28390_00_cover.qxd 1/16/09 4:03 PM Page 1 Summary of Content The geologic past of Florida is mostly out of sight with its maximum elevation at only ~105 m (in the panhandle) and much of south Florida is virtually flat. The surface of Florida is dominated by subtle shorelines from previous sea-level high-stands, karst-generated lakes, and small river drainage basins What we see are modern geologic (and biologic) environments, some that are world famous such as the Everglades, the coral reefs, and the beaches. But, where did all of this come from? Does Florida have a geologic history other than the usual mantra about having been “derived from the sea”? If so, what events of the geologic past converged to produce the Florida we see today? Toanswer these questions, this module has two objectives: (1) to provide a rapid transit through geologic time to describe the key events of Florida’s past emphasizing processes, and (2) to present the high-profile modern geologic features in Florida that have made the State a world-class destination for visitors. About the Author Albert C. Hine is the Associate Dean and Professor in the College of Marine Science at the University of South Florida. He earned his A.B. from Dartmouth College; M.S. from the University of Massachusetts, Amherst; and Ph.D. from the University of South Carolina, Columbia—all in the geological sciences. Dr. Hine is a broadly-trained geological oceanographer who has addressed sedimentary geology and stratigraphy problems from the estuarine system out to the base of slope. -
Florida Options for Marine Conservation
pg.1 greenpeace.org Florida Options for Marine Conservation Potential no-take marine protected areas Fully protected marine reserves, where no harvesting is allowed, are heralded by scientists as offering the greatest ecosystem and biodiversity benefits. Such areas in Florida, while only covering less than 0.001 percent of Florida’s waters, have shown to enhance lobster and game fish fisheries and are popular destinations for recreational diving and snorkeling. Examples of exciting opportunities for potential future fully protected conservation zones within Florida waters include the following: Location: off Tavernier Key in the Florida Keys Snapper Ledge Environment: shallow coral reef (and similar environments) Snapper Ledge, a popular dive site off of Tavernier in the Florida Keys, is home to some of the most dense and diverse marine life populations in the area. Divers regularly report the presence of large schools of grunts, snappers, and many other species of fish, including parrotfish, rays, lobsters, and more. Divers report that marine life (especially snapper) is concentrated here. One of the largest and healthiest Boulder Brain Corals (Colpophyllia natans) in the Upper Keys can be found on Snapper’s Ledge. This site is reported as an exceptional location for both snorkeling and diving—a Image courtesy NOAA serious “must dive” site in the keys. There is currently an effort seeking Sanctuary Preservation Area (SPA) status for Snapper Ledge, supported by local dive operations and conservation groups. SPA status is essentially a “no-take” zone. There are currently only 18 small SPAs in the Florida Keys National Marine Sanctuary (FKNMS). Many more shallow and threat- greenpeace.org ened coral reefs there deserve SPA status. -
