Sounds of glacial melt captured using underwater microphones
Listening to icebergs could help to assess the extent of glacier melt, scientists report.
Researchers in Poland and the UK used underwater microphones to record the sound of ice calving away from a glacier in Norway.
Combining this with time-lapse photography, they discovered that the birth of different types of icebergs have their own acoustic signature.
Monitoring this could help to determine how much ice is being lost and the effect this could have on global sea level rise.
The findings are reported in the journal Geophysical Research Letters.
