Description:
Abstract:
The fragile coral reefs of the Florida Keys form the largest living coral reef ecosystem in the continental United States. Lining the shallow outer shelf approximately 5 to 7 km seaward of the keys, the reefs have national aesthetic and resource value. As recently as the 1970s, the coral reefs were the heart of a vibrant ecosystem. Since then, the health of all ecosystem components has declined markedly due to a variety of environmental stressors. Corals are succumbing to bleaching and diseases. Species that are the building blocks of solid reef framework are increasingly being replaced by species that do not construct reef framework. Algal proliferation is increasing competition for space and hard surfaces needed by coral larvae for settlement. Decline of the coral reef ecosystem has significant negative implications for economic vitality of the region, ranging from viability of the tourism industry attracted by the aesthetics to commercial fisheries drawn by the resources. At risk of loss are biologic habitats and reef resources, including interconnected habitats for endangered species in shoreline mangroves, productive nearshore marine and wetland nurseries, and economic offshore fisheries.
In 1997, the U.S. Geological Survey's Coastal and Marine Geology Program undertook a comprehensive 7-year-long mission to consolidate, synthesize, and map new (1997) and existing geologic and biologic information into a digitized regional database and one-volume reference source on the geologic history of the Florida Keys reef tract (this report). The project was conducted in cooperation with the National Oceanic and Atmospheric Administration's National Marine Sanctuary Program. The purpose was to examine the natural evolution and demise of several coral reef ecosystems over the past 325,000 years, with an eye toward gaining a better understanding of the cause of the reef decline observed today. Scientific data and datasets presented in this report are intended for use by others in ongoing efforts to delineate which components of reef decline in the Florida Keys may be natural and which may be a result of human activities.

Process_Step:
Process_Description:
Five seismic surveys were merged to produce the most contiguous seismic coverage available in the Florida Keys National Marine Sanctuary. Bedrock-surface and sediment-thickness data were read from the seismic records at 5-min intervals. These data provided distances (depths) from the water surface to the images or reflections marking the bedrock and sediment surfaces in milliseconds. Where significant changes in depth to bedrock or sediment thickness occurred between the 5-min intervals, readings were taken at shorter intervals. Seafloor-surface depth, bedrock depth, and sediment/reef thickness in milliseconds were then converted to depths in meters in an Excel spreadsheet. Isolated data on bedrock depth below sea level, interpolated from non-geolocated maps of Enos (1977, scale 1:80,645), supplemented the merged bedrock dataset. Data points on the final integrated datasets were then contoured manually with the aid of prior field knowledge and aerial photomosaics that provided visual clues regarding geomorphic shapes and trends. Coral and sediment cores and radiometric dating were used as supplemental evidence to determine bedrock depth and age, and Holocene thickness. Benthic features/ecosystems were primarily derived from aerial photomosaics. Mosaics were assembled by cropping 67 black-and-white overlapping frames of photos (1:48,000) taken in 1991 and 1992 by the National Ocean Service (NOS/NOAA/National Geodetic Survey) for the purpose of mapping shorelines along the Florida Keys. These mosaics supplemented those taken in 1975 by the Florida Department of Transportation to evaluate anthropogenic changes in the Keys. The 1975 photos were used in the published photomosaic study. Interpretation of the new photomosaics was supported where necessary with color photos taken in 1983 for an inventory of seagrass and coral reef coverage by the U.S. Environmental Protection Agency (EPA). The EPA volume available to this project covered the reef tract from Sombrero Key south of Vaca Key to just west of Cosgrove Shoal, located south-southwest of the Marquesas Keys in the Gulf of Mexico.
