Resource Description: 2002 Oculina Banks Multi-beam and Sidescan Bathymetry
The multi-beam system was mated to a Differential GPS unit, DMSO 5 TSS motion sensor (quantified heave, pitch and roll), and a SG Brown gyrocompass (measures yaw). HYPACK navigation system was used to maintain vessel course throughout the survey. Sensor data were compiled in ISIS Shipboard Data Acquisition and Image Processing System and initially logged to .xtf data files. Files were post-processed using CARIS software to remove outliers, correct for sound velocity and tidal stage.
