| Objective | The impacts of source detection methodology or leakage of fluids in the column by an AUV are multiple: 1) Exploration of hydrothermal or cold fluids; 2) Leak detection on offshore installations; 3) Monitoring of emissaries and estuarine zones with regard to compliance with European regulations (Directives 2000/60 / EC, 2006/118 / EC and 2006/11 / EC). The approach conventionally used for the measurement of these fluid outlets is often based on imprecise and insensitive long-range detection coupled with samples often analyzed after the cruise. This approach remains unsatisfactory for various reasons: it is costly because it requires time, human resources and heavy seagoing resources (ROV). Raman spectroscopic chemical analyzes will be carried out concomitantly with acoustic measurements on areas with fluid outlets such as emissaries of purification plants or gas or fresh water outflows through sedimentary structures. |
