These data are the result of a multi-beam echosounder survey conducted in the OHAPC by the M/V Liberty Star in October 2002. Two forms of data are available: 1) geotifs available through the on-line OGIS (www.uncw.edu/oculina) on the OGIS CD, and from CoRIS (See Network Resource), and 2) XYZ ASCII format data for the high-resolution bathymetry, available through CoRIS. Although requested in the original contract, backscatter in the form of raw X-Y-Amplitude data was not recorded during the survey.The data presented in the Oculina Banks Geographic Information System (OGIS) was collected as part of a cooperative project between: the National Oceanographic and Atmospheric Administration's (NOAA) Undersea Research Program, NOAA Fisheries (also primary sponsor of OGIS), NOAA Ocean Service, NOAA Ocean Exploration Program, the U.S. Geological Survey (USGS)-- Coastal and Marine Geology Program, Harbor Branch Oceanographic Institution (HBOI) and Florida State University. An Oculina Geographic Information Sys/tem (OGIS) provides a comprehensive, interactive data source for the Oculina Banks Habitat Area of Particular Concern (OHAPC), a marine protected area off the east coast of Florida in 70 to 120 meters of water depth. Data layers include: : multi-beam bathymetry, single-beam bathymetry, sidescan mosaics, sediment analyses, resulting interpretative maps of habitat types, video and still imagery from submersible (human occupied and remotely operated vehicles) dive transects and point counts (fish and habitat cover), and dive narratives.
