| The development of telecommunications and in particular the constantly increasing demand of digital services make the submarine telecommunication cables very strategic and the users of these services very sensitive to interruptions or degraded quality. Then, the main cause of faults on submarine telecommunication cables is trawler or anchor damage. Therefore, once the route has been finalized, only a good quality of burial can reduce the risks linked to these external aggressions. The tools used to-day by France Telecom for burial are: a standard sea-plough, with a share, towed by the cableship simultaneously to the laying operation; ROVs (SCARAB) to post-lay bury cables by jetting, repair buried cables and rebury the cable after repair. |

| After a general presentation of the Thau lagoon together with its geographic location, socio-economic activities linked to shellfish culture and fishing, this paper investigates the health conditions of the shellfish harvesting areas. I he influence of heavy rainfall following a prolonged drought period is underlined as a determining factor of the momentary bacterial pollution in the harvesting areas, leading to a suspension of sales based on analyses relying solely on the detection of faecal coliforms. As of 1989, bacteriological monitoring was reorganized in the form of a data collection network taking into consideration environmental assessments of water quality as well as shellfish hygiene in order to protect consumer health. Its extension to the... |
