This report presents the work carried out from 1st December 2017 to 31st Mai 2018 under SEAOX project. It aimed to study the feasibility of scattering-based methods for bubbles monitoring, applied to marine plants production. Backscattering theory is first considered, based on the operation of a sediment monitoring device, adapted to project goals for the occasion. The second studied option aims to make underwater sound speed and attenuation measurements for a set of frequencies in order to access the characteristics of the bubbly medium. Both theories and experimental results are presented and documented in this report, that will support further investigations.
