Sounds of the sea: Listening online to the ocean floor (BBC)

"The cable is going underneath here," says Benoit Pirenne, standing at the water's edge on Canada's Vancouver Island. "It's going out 500 miles (800km) in a big loop in the ocean, coming back in the same place."
The Vancouver cable connects a network of scientific instruments on the floor of the north Pacific, some as deep as 1.5 miles (2.5km).
Set up by Pirenne and his colleagues at the University of Victoria, and called Neptune Canada, they continuously monitor the marine environment.
The scientists are harvesting large amounts of information, including water pressure readings that help them better understand the movement of tsunamis through oceans, which they hope will lead to more accurate warning systems.
But they are also listening.
