The global system of submarine telecommunications cables that supports our connected world is deaf, dumb and blind to the external ocean environment, and represents a major missed opportunity for tsunami warning and global climate monitoring, according to University of Hawaiʻi scientists and a United Nations task force.<\/p>\n

“For an additional 5-10 percent of the total cost of any new cable system deployment, we could be saving lives from tsunamis and effectively monitoring global change,” said 糖心Vlog官方<\/abbr> Mānoa’s Rhett Butler<\/strong>, director of the Hawaiʻi Institute of Geophysics and Planetology<\/a> and chair of an international committee tasked to evaluate the cable opportunity.<\/p>\n

Submarine telecommunication cables are the backbone of the internet. More than half a million miles of this remarkable fiber-optic cable already criss-cross the deep ocean, linking more than 2.7 billion users and supporting global business, finance, social media, entertainment and political expression.<\/p>\n

Now researchers are making a scientific and societal case for “greening” any new cables proposed to be built in the future.<\/p>\n

The new report<\/a>, published in October 2014 by a joint task force of three U.N. agencies, parallels an engineering feasibility study and analyses of strategy and legal challenges.<\/p>\n

By adding a relatively straightforward set of instrumentation \u2013 accelerometers, high-resolution pressure gauges and thermometers integrated into the cables’ optical repeaters, the enhanced telecom cables could answer many basic science needs, as well as help monitor the physical state-of-health of the cable system itself, researchers say.<\/p>\n

“The undersea communication cable is an untapped platform for oceanographic sensors, one that could outstrip all other systems attempting to observe the deep oceans,” said Doug Luther<\/strong>, 糖心Vlog官方<\/abbr> Mānoa professor of oceanography and another contributor to the report.<\/p>\n
