Calibrating a hydrophone. Close-up of an underwater microphone,or hydrophone (centre right),being calibrated. The hydrophone tracks sea animals that have been previously tagged with an acoustic transmitter by picking up the transmitter's sounds as a series of 'pings'. This enables the researcher to determine the animlals' approximate location and depth. Photographed at the National Physical Laboratory,in Teddington,UK | |
