Less Ice, Fewer Calling Seals

For several years, a team of researchers from the Alfred Wegener Institute used underwater microphones to listen for seals at the edge of the Antarctic. Their initial findings, just released in the journal Frontiers in Ecology and the Environment, indicate that sea-ice retreat has had significant effects on the animals’ behaviour: when the ice disappears, areas normally full of vocalisations become very quiet.
