Project Details


The aim of the SIGMA project is to investigate the relations between the acoustic parameters of
marine sediments (reflection factor, sound velocity, attenuation, dispersion etc.) and their
geophysical and geotechnical properties (sediment type, grain size distribution, cohesion, gas
content, etc.).
The acoustic parameters of the sediments are estimated from wide frequency band
measurements, using a steerable parametric array combined with a towed array of receivers.
