Sme years ag, Michel André fund himself staring at the bdy f a dead whale n a beach in the Canary Islands. It was bvius that the animal had been struck vilently by a ship—but why? Only later, after surveying the whales which lived in the area and measuring the increase f sund pllutin frm ships did it becme clear that there was a link.
The whales had becme desensitised t the nise f appraching bats and were being struck by them, ften seriusly. “We never thught that this culd be smething that culd kill，” recalls (回忆起) André， wh is the directr f the Labratry f Applied Biacustics at the Technical University f Catalnia, Barcelna.
André has spent 20 years develping an advanced system t better understand why incidents like this happen. His underwater micrphnes have expsed a wrld f deafening sund and animal cmmunicatin never bserved with such clarity (清晰) befre.
It was nt an easy task. Sund waves dn't travel thrugh water in the unifrm, predictable way they d thrugh the air. Instead, the temperature, salinity (盐度) and flw f water have great effects n their path.
What can be dne? One slutin is t change shipping rutes t curse where ships are statistically less likely t meet animals. It's als pssible t slw ships dwn t 18km/h r less, which is less likely t seriusly injure a whale.
As fr dealing with the rt cause f the prblem, the UN's Internatinal Maritime Organisatin has already published guidelines n hw t quieten ships, but it will be a while befre the effects f such changes might be bserved.
“The cean is nt ur wrld，” cmments André. But it is urs t lk after. And thanks t his wrk, we can better understand the effects f subsea sund pllutin.
