Latitude Geological History : Geological History 1.8 million years ago to 10,000 years ago Pleistocene Ice Ages Large sea level fluctuation Reef establishment along FL Platform – subtropical, warm, nutrient-rich waters Dead corals provided good foundation for new coral growth Key Largo Limestone 75-200 ft thick Last major sea level drop exposed FL Keys Geology : Geology Upper and Middle Keys - Key Largo Limestone – skeletal remains of corals, invertebrate shells, marine plant and algal debris, and lime-sand Lower Keys – Miami Oolite – well sorted ooids, with other skeletal material and some quartz sand Paleo tidal bars – sandy and oolite shoal traversed by many channels Geology : Geology Key Largo Limestone Miami Oolite Geology : Geology Windley Key Geological Park Limestone quarry provided railroad bridge supports for Henry Flagler’s Overseas Railroad Decorative Keystone quarried until 1960’s Limestone cutter Marine Habitats : Marine Habitats Coral Reefs Seagrass Beds Mangroves (Mangal) Submerged Resources Coral Reef Zonation : Coral Reef Zonation Light intensity and wavelength Wave energy Water Temperature Hardbottom : Hardbottom Close to shore Low species diversity Dominated by gorgonians, algae, sponges Gorgoniancourtesy Florida Keys National Marine Sanctuary Patch Reefs : Patch Reefs Shallow water Nearshore Grow upward then expand outward Bank Reefs : Bank Reefs Spur & Groove Formation High Species Diversity Coral zonation by depth Presence of Elkhorn Coral Human Impacts on Reefs : Human Impacts on Reefs Pollution Overfishing Tourism Aquarium/Souvenir Trade Global Climate Change – Coral Bleaching Introduced Species Seagrass Beds : Seagrass Beds Stabilize Sediments Water Clarity Food and Shelter Human Impact on Seagrass Beds : Human Impact on Seagrass Beds Dredging and Filling Propeller Scaring Eutrophication – high nutrients, low oxygen Mangroves : Mangroves Shoreline Protection Nursery Threatened and Endangered Species Human Impact on Mangroves : Human Impact on Mangroves Dredging Water Pollution Urban Development Oil surrounding mangroves Urban encroachment Submerged Resources : Submerged Resources Adolphus Busch Wreck – 210 ft freighter intentionally sunk in 1998 to create an artificial reef Looe Key Marine Sanctuary : Looe Key Marine Sanctuary 7,000 years of coral growth Protected area of high ecological importance Pristine example of Patch and Bank Reef in Lower Keys Many endangered species Looe Key : Looe Key Looe Key : Looe Key R/V Columbus Iselin – ran aground August 1994 Severe scar damage – 6 scars on 4 coral spurs $4 mil.
