Undersea Cables Help Protect Rare Ocean Wildlife

Quick Smiles:

• Researchers are using underwater cables to monitor endangered orcas.
• A new technique can detect the whales’ unique sounds and help keep them safe.
• This innovation could transform ocean conservation worldwide.

A hidden network of underwater fiber optic cables is now helping scientists uncover the secret lives of elusive marine mammals.

At the University of Washington, researchers have placed 1.25 miles of cable in Puget Sound to listen in on endangered southern resident orcas just south of the Canadian border.

The technology, called distributed acoustic sensing, sends laser pulses through these cables and analyzes vibrations made by the whales’ clicks.

It has already been used for earthquake monitoring, and now it’s showing promise for marine conservation.

Dr. Shima Abadi hopes this system will help map orca activity, alerting ships to slow down and keep a safe distance, protecting these vulnerable creatures.

“This innovative approach could be a break-through in conservation efforts and open new possibilities to expand analysis on a much larger temporal and spatial scale,” said Abadi.

With 870,000 miles of undersea fiber optic cable globally, this strategy could soon offer protection far beyond local waters.
