This metadata record is the parent record for this multi-beam echosounder (MBES) survey, which includes the following products: 1) bathymetric grid, 2) XYZ ascii table created from the grid, 3) colored coded shaded geotiffs from the grid, 4) backscatter mosaic, 5) XYA (amplitude) ascii table created from the mosaic, and 6) geotif of backscatter draped on the bathymetric grid. All products are available through an on-line Oculina Geographic Information system (www.uncw.edu/oculina) and on an OGIS CD. Some data sets are also posted on NOAA's Coral Reef Information System (CoRIS) at www.coris.noaa.gov. Another product that will not be distributed, but will be used as input to habitat classification software (QTC MultiView (website)), are raw data files logged to disk using the the Simrad EM3002 MBES data acquisition software. These raw files contain packets of information (depth soundings, navigation, attitude, sound velocity profiles, UTC time) that the acquisition software logged sequentially in time. The raw data format is available from Kongsberg-Simrad (website). The MBES system was provided by Seafloor Systems Inc. and the support vessel was UNCW's 70-ft. R/V Cape Fear. This survey is part of an on-going partnership effort funded by the NOAA Coral Reef Conservation Program (CRCP). This survey was funded by a CRCP grant to Andrew David, NOAA Fisheries - Panama City, and Andrew Shepard, NURC/UNCW. In addition to partners above, other partners include UNCW's Spatial Analysis Lab, US Geological Survey, and the S. Atlantic fishery Management Council. The 2005 multi-beam survey provides the highest resolution bathymetric map ever acoustically recorded in the OHAPC. Survey products will be used for several purposes including: 1) construction of a habitat map and 2) to accurately position past and future sampling and underwater observations (e.g., grab samples, ROV transects, and submersible dives. The survey was supported by Seafloor Systems, Inc., Portland, (www.seafloorsystems.com) Oregon using a Simrad EM 3002 multi-beam system. The survey was funded by NOAA Fisheries (www.sefsc.noaa.gov) and overseen by the NOAA Undersea Research Center at UNCW (www.uncw.edu/nurc). 20050615 20050620 publication date In Work As needed -80.0000 -79.0000 29.0000 28.0000 CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Bathymetry/Seafloor Topography > Bathymetry EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Mapping EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs > Marine Protected Areas CoRIS Discovery Thesaurus Geographic Information > Bathymetry ISO 19115 Topic Category elevation 006 none multibeam bathymetry deep-water reefs ocean floor topography backscatter CoRIS Place Thesaurus OCEAN BASIN > Atlantic Ocean > North Atlantic Ocean > Florida Reef Tract > Oculina Deepwater Reef (28N079W0001) COUNTRY/TERRITORY > United States of America > Florida > Brevard County > Oculina Deepwater Reef (28N079W0001) CoRIS Region Florida There are no constraints for use of geotif files included on the OGIS CD, which is available from the P.O.C.

The raw survey data and processed XYZ data may also be available upon request from the P.O.C. None Data are believed to be logically consistent, though no tests were performed. The initial surveys produced an extremely large dataset (62 CDs) of raw data in Caris' cross-track format. To create the geotifs presented in the OGIS, this data set was reduced by post-survey processing including: corrections for sound velocity and tidal stage, removal of outliers and data gaps, and calculation and assignment of mean values for 3m X 3m cells throughout the survey area. 1 meter 0.05% of water depth The bathymetry and backscatter data were collected along a continuous swath perpendicular to the direction of the ship using a Simrad EM 3002 multibeam sonar system. The data were collected in the raw format .all Simrad file. The data are cleaned of bad navigation and depth readings in CARIS HIPS 5.4 swath editor. The depth readings are gridded into a common grid. The gridded data are converted to an XYZ ASCII format file (Longitude, Latitude, Attribute). The raw backscatter was saved during the survey. The multi-beam system was mated to a Differential GPS unit, APPLANIX POS/MV (quantified heave, pitch, roll, and yaw heading). HYPACK navigation system was used to maintain vessel course throughout the survey. Sensor data were compiled in SIS Shipboard Data Acquisition and Image Processing System and initially logged to .all Simrad data files. Files were post-processed using CARIS HIPS 5.4 software to remove outliers, correct for sound velocity and tidal stage. HIPS was also used to mosaic backscatter and produce XYA files. 20050620 John Tamplin Seafloor Systems, Inc. President mailing and physical address
