The scientific and societal case for the integration of environmental sensors into new submarine telecommunication cables
Our ocean and climate are experiencing global changes that will affect us and our descendants. Without access to the seafloor for fundamental oceanographic measurements, scientists cannot quantify and respond to the dilemma facing humanity. As we begin to make submarine telecommunication cables environmentally aware “green cables”, we look to a future where cables serve a dual purpose, both as communications infrastructure and a scientific backbone for monitoring tsunamis, earthquakes and the world’s seafloor temperatures and circulation.

Using Submarine Cables for Climate Monitoring and Disaster Warning: Strategy and Roadmap
This report presents a strategy and roadmap to move forward this vision of incorporating sensors into submarine cables. Nowadays, submarine telecommunication cables that traverse oceans transmit the global Internet, but are deaf, dumb and blind to their ocean environment around them. A future is envisioned when telecommunication companies integrate ocean-observing sensors within their submarine cable systems. This new sensory data would crucially advance our knowledge in monitoring global climate change and tsunamis in the deep ocean.

Using Submarine Cables for Climate Monitoring and Disaster Warning: Opportunities and Legal Challenges
Recognizing the newness of such uses of undersea telecommunications cables and the complexity of national and international legal-regulatory regimes, this report examines opportunities and legal challenges arising from dual-purpose telecom-marine data cables for ocean and climate monitoring and disaster warning.

Using Submarine Cables for Climate Monitoring and Disaster Warning: Engineering Feasibility Study
This report investigates technical feasibility of modifying repeaters to support science instruments for incorporation into commercial telecom cables systems. Allowing and improving long term measurement and data collection, a “Green Repeater" equipped with science instruments will indeed contribute to the effort of better understanding the oceans and the changing climate.
