Listen to porpoises on the Zierikzee jetty
A special technical installation on the jetty of Zierikzee makes it possible for people to hear the porpoises in the Oosterschelde. The porpoise sounds are captured using a hydrophone, which is attached to a buoy in front of the coast, ANP reports.
"With the push of a button the visitor hears the sounds the aimals emit." initiator Frank Zanderink of Stichting Rugvin said. The porpoise is the smallest species of cetaceans found in the Netherlands.
About 30 porpoises live in the Oosterschelde. For underwater orientation, to communicate and catch fish they transmit high frequency sounds, which they catch again when the sounds rebound.
