3D-Bathymetry and Scientific EchoSounder -SeapiX -

TOYO Corporation

• Objectives： • This presentation is prepared for the introduction about the 3D Bathymetry and Scientific Multibeam Echosounder “SeapiX” of iXblue

• iXblue’s SeapiX is developed as A sonar system that can quantize / mapping of the seafloor topography, fish school and other biomass at 1.6°x 1.6°in the 120°×120°volume which has “dual-milscross” multibeam sonar processing system.

• SeapiX is expected to show a good performance not only bathymetry, but also biomass-mapping using the sharp horizontal beam footprints.

Maximization of sustainability about the fish market = Effective investigate method for Biomass
