Tiny fiber-optic cables on seabed can do a lot more than you can imagine. Now, they can listen to silent whales. Here's how

Tiny fiber-optic cables on seabed can do a lot more than you can imagine as researchers have found that these underwater communication cables can detect silent whales by sensing low-frequency pressure waves created while they swim. The discovery could improve whale monitoring, conservation efforts, and ocean research. Scientists used existing fibre-optic cable networks, ship data, and physics to develop a new method for tracking whales even after they stop vocalizing.
