The extent, distribution, and composition of major benthic communities (e.g., hard bottom, soft-bottom, dense Thallasia sp. seagrass, sparse seagrass, etc.) across bays and marine areas influence the fish, invertebrate, and larger vertebrate communities (e.g., sea turtles, manatees) they support. Benthic communities can change with alterations in location, quantity and quality of freshwater and sediment inputs (e.g., CERP), nutrient levels, major storm events, and heavy visitor use (e.g., repeated boat groundings, scarring, and anchoring damage). Analysis of remotely-sensed data provides the spatial extent and composition of major benthic communities across relevant areas of marine parks allowing tracking of changes in large-scale patch size and shape at a broader scale than site-specific studies.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "These images and data were all collected as part of a larger project to create a benthic habitat map for the Dry Tortugas National Park.
