Whale Sounds
b'While we\\u2019ve known for a long time that whales sing and dolphins communicate in clicks, we don\\u2019t really know much about what they\\u2019re saying to each other. A team of researchers from the Scottish Association for Marine Science dropped 10 microphones close to the sea floor off the western coast of Scotland, and recorded a full year of sounds to learn more about the sea life activities. Nienke van Geel is an expert in marine mammal ecology and acoustics, and he joined Sean to discuss the research.'
