Green Cables for ocean and climate monitoring and disaster warning
Erica Campilongo, ITU
Why are sensors required? Tsunami
East Japan, 11 March 2011 15,883 deaths US$235 billion
Why are sensors required? Global Climate Change
The InitiativeThe deep ocean is largely unknown…
There is a need and opportunity to extend observations and monitoring over much wider area of the global oceans
How could submarine cables be used as a real-time global network to monitor climate change and to provide tsunami
warnings?
A new generation of regional scientific cabled ocean observatories is emerging
Submarine telecommunication cables equipped with sensors to measure key variables such as water temperature,
pressure and acceleration on the ocean floor are viewed as vital to monitor climate change and to provide tsunami
warnings.
ITU with UNESCO-IOC and the WMOestablished a joint task force (JTF) tasked to investigate
using submarine telecommunications cables for ocean and climate monitoring and disaster warning
over 80 international experts from the science, engineering, business and law communities
Five Committees1. Science and Society2. Business Models3. Engineering4. Legal5. Publicity, Outreach and Marketing
Three reports were commissioned and published on Strategy and Roadmap, Engineering Feasibility, and Opportunities and Legal Framework.
JTF Vision and Goals Define needs Prove technical feasibility Build trust and confidence Demonstrate impact Estimate costs Identify partners Draw up business model Study legal aspects Sketch out a pilot project for development and
deployment of an initial “green cable” system
Distributed seabed sensors across oceans have unique value
Without such sensors we cannot really understand ocean processes
Submarine telecommunications systems offer a platform for these sensors
Supporting such sensors would be a positive gesture by system owners
