Construction of the obsea cabled submarine observatory

Puntos clave

The aim is to construct a submarine observatory for continuous monitoring of seafloor data.
Monitored functioning parameters of stations for maintenance interventions.
System operated over two years to evaluate data transmission.
Implemented a near real-time data transmission chain between seafloor and shore.
Successfully transmitted seafloor data in near real-time.
Increased reliability of the system significantly over the two-year period.
Enabled permanent technical monitoring and alert transmission from the seafloor.

Resumen

VIEWPOINTSessions 33 Figure 1. Data transmission chain between seafl oor and user on shoreThe functioning parameters of the stations are also monitored, for a proper preparation of the maintenance interventions scheduled at each periodic cruise over the Var Valley.The data transmission results over the two years are presented. ConclusionsThe system presented here off ers the functions of a near real time sea observatory, at a modest cost.In addition to delivering the seafl oor data in near real time, it allows a permanent technical monitoring of the seafl oor equipment and can transmit alerts from the seafl oor.These two years of operation allowed to signifi cantly increase its reliability.
