Multispectral Backscatter Evaluation Project

QPS Chief Scientist, Dr. Jonathan Beaudoin, has been working with academic partner Dr. Craig Brown (Nova Scotia Community College (NSCC)) and with Mike Brissette (R2Sonic) to assist in field evaluation of the new multispectral capabilities of R2Sonic multibeam echosounders.  Trials were conducted in the Bedford Basin in Halifax, NS, Canada in August, this being the second set of field trials.  Early results from the first field trials held in March 2016 were presented by Dr. Beaudoin and Dr. Brown at the GeoHab conference in Winchester, UK in May of 2016.  For both trials, QPS provided software support for acquisition and data processing to facilitate the R&D process for R2Sonic.  QINSy, Qimera and FMGT were configured in a real-time mode to allow for immediate production of backscatter imagery.  This enabled quick evaluation of results and facilitated a dynamic experimental approach to the trials.  Multispectral backscatter is a new capability that has the potential to be a game changer for seafloor backscatter imaging.  The capability to image the seafloor simultaneously with widely separated acoustic frequencies will allow for improved classification and characterization capabilities in addition to a host of other applications that are yet to be discovered.


For tomorrow’s trials, we’ll be setting up FMGT to run three projects simultaneously to make three separate spectral band mosaics with the same workflow outlined above.
