Underwater livestream in Greenland gathers evidence of climate change — and lets the public listen

Scientists in Greenland have installed an underwater microphone in Disko Bay. Recording the sounds will allow them to study how climate change is affecting the area, by tracking the presence of species and changes in noise. They have also made the microphone's transmission open to the public, on an online stream called DISKO LIVE. The World's Host Marco Werman speaks with Outi Tervo, the lead scientist behind the project.
