POSA (Propagation des Ondes Sismiques d’origine Anthropiques) is an ANR project led by SHOM. MAREE was asked to measure and modelize the underwater acoustical propagation of calibrated explosions in the bay of Hyères.  

In fact, every year, many countermining operations on unexplosed ammunition dating from the Second World War take place off the French coast. This study aims to better understand their environmental effects.

Objective: Analyze those measures to set up a propagation model to better understand the impact of mine-clearance and thus optimize the operating protocol for countermining operations.
