The National Oceanographic and Atmospheric Administration's (NOAA) Undersea Research
Center at the University of North Carolina at Wilmington (NURC/UNCW) coordinated an acoustic
survey in portions of the Oculina Habitat Area of Particular Concern from June 14-19, 2005.
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).

Colored, shaded geotifs for the survey area were created by Seafloor
Systems Inc. using Caris HIPS 5.4 software. 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.

XYZ ASCII file is a 3-column table of longitude, latitude and elevation.
Each point is average center of 3 meter square grid cell. Colored, shaded
geotif maps in OGIS were created using these points and CARIS HIPS 5.4 software.
