2017: The R2Sonic Multispectral Challenge

When we released the revolutionary R2Sonic Multispectral mode, we gave users the ability to collect backscatter data at different frequencies in one pass and with one MBES only. In Multispectral mode, the acoustic responses of seafloor sediments at different frequencies coincide in time and space. This was a significant contribution for the advancement of research in bottom characterization.

 

With this innovative breakthrough, R2Sonic founders launched the 2017 Multispectral Challenge. They opened the competition worldwide, challenging researchers and scientists across the globe to explore ways to use multispectral backscatter data for determining bottom type. Six competitors submitted white papers each with the goal to develop an algorithm that robustly and repeatedly could determine bottom type based on multispectral data.

All research papers took different mathematical approaches. So who won?

Of the six competitors, Timo Gaida from Delft University of Technology was awarded first place. The prize? The new Sonic 2026 system. The revolutionary Sonic 2026 system can collect data at up to five different frequencies, ranging from 200kHz to 450kHz and with a low frequency option at 90/100kHz.
