Ocean Observation, Climate Change and Disaster Warning: the Context David Meldrum Consultant, IOC/UNESCO, Paris email@example.com
Contents of presentation Is climate changing? Ocean observing systems already in place –Weather and climate –Disaster warning The challenges of the deep ocean Opportunities for cable operators to make a difference
The evidence for climate change: global temperatures
The evidence for climate change: global sea level
Challenges of the deep ocean (compared to space) Satellites cant see below the sea surface Instruments have to withstand high pressure and corrosion No energy source (e.g. solar panels) Difficult for communications and imaging
Cables offer a solution Vandal-proof in the deep ocean Instantaneous communications Energy source Next generation commercial repeaters to include built-in tsunami sensors? Why not other sensors as well? –Ocean properties such as temperature and salinity –Seismometry –Passive acoustics
Passive acoustics has been used from cables before Blue whale migrations using SOSUS
Ocean acoustic pollution is a major issue IOC, Paris, Sept 2011
Conclusions The deep ocean is poorly observed Next generation cable repeaters could make a major impact Important climate variables could be measured Acoustic sensors would cast new light on marine mammals Cables offer the ideal solution for tsunami warning –Vandal resistant –Instant communications –Energy available –Could be a business opportunity –Or why not just be green and eco-friendly and improve your image! Suggestion: establish a small enthusiastic group to sketch out a limited pilot project
Cables are the future! TAT-1, Oban, Scotland Thank you!
