An interrogator (a) sends a laser pulse from a ground station through the fiber optic cable.The cable has defects (b) which underwater sounds slightly displace.This sends back a signal that the interrogator can interpret as acoustic data over regularly spaced intervals or channels (c).

Yes we can monitor whales with existing fiber optic cables

After feeding at depth, sperm whales off the coast of Sri Lanka return to the surface — and poop. This “whale pump” provides many nutrients, in the form of feces, to support plankton growth. It’s one of many examples of how whales maintain the health of oceans described in a new scientific paper by UVM’s Joe Roman and nine other whale biologists from around the globe. (Photo: Tony Wu)

“As long-lived species, they enhance the predictability and stability of marine ecosystems” “Consider the subtleness
