Timo C. Gaida from Delft University of Technology
winner of the Multispectral Challenge!

The winner was announced at GeoHab 2018 in Santa Barbara, California on May 8 2018.

R2Sonic launched the Multispectral Challenge a year ago at GeoHab 2017, following the introduction of the Multispectral Mode available with R2Sonic Multibeam Echosounder Sonic 2026.

We want to thank all the participants who submitted a research paper to the Multispectral Challenge for their contribution to the bottom characterization area of research.  Also, thank you to the organizers of GeoHab for their continuous support.

We remain committed to support the scientific community by continuing to revolutionize the industry of underwater mapping with breakthrough solutions.

Determining bottom type based on multispectral backscatter data

Six scientists from six Institutions from around the world have researched this topic thanks to the multi-frequency backscatter data provided by R2Sonic.

Surveying the seafloor with the MBES Sonic 2026 enables you to collect backscatter data at different frequencies. These multi-frequency measured acoustic responses coincide in time and space which was suggested to be a breakthrough in bottom characterization research.

In these research papers you will learn about:

  • The added value that multispectral backscatter data brings to bottom characterization.
  • The different approaches the six researchers took to develop an algorithm to determine bottom type based on multispectral data.
  • The area of this research that remains unsolved.

Get on board, don’t be left behind, get the multispectral backscatter data!
