We’re doing it again!

This time, three universities collaborated to collect Multispectral TruePix® data:

  • Northern Arizona University (NAU)
  • Nova Scotia Community College (NSCC)
  • the University of Southern Mississippi (USM)

QPS has also been instrumental in making the R2Sonic Multispectral Water Column Challenge possible, by developing the appropriate tool to process Multispectral  TruePix® data and by offering free licenses to participants.  


Similar to the enhanced seafloor discrimination capabilities identified through the first R2Sonic Challenge, for the R2Sonic Multispectral Water Column Challenge, we requested submissions exploring new and improved identification, differentiation and characterization of targets in the water column based on the responses observed at different frequencies.


The winner was going to be announced at the GeoHab conference in May 2020, and as the event has been postponed, the R2Sonic Multispectral Water Column Challenge has been extended.


Research papers will be due in February 2021.




Thank you to our partners for making the R2Sonic Challenge possible!

Don’t miss out!  Stay in the loop.

Sign up and we’ll share the latest information on Multispectral Water Column as soon as it is available.
