Description
The Engineering and Development Section of the International Monitoring System (IMS) Division is responsible for the installation and maintenance of the hydrophone based hydroacoustic stations within the CTBTO’s IMS. All hydroacoustic stations are now installed, certified and providing near real-time hydroacoustic data to the International Data Centre in Vienna, Austria. Five of these stations are based in remote island locations, and one station is located in Australia. The stations comprise of hydrophones suspended in the water column which are cabled to shore with electro-optical trunks. Some stations are in their second decade of operation, the newest station was certified in 2017. High data availability from these stations is achieved by identifying and mitigating station specific risks. This presentation will consider some current risk mitigation issues with respect to the in-water component with particular emphasis on HA01 Australia.
