Scientists are learning to decode the sounds of icebergs

Sarah Laskow, Atlas Obscura, reports about what scientists have learned from “Listening to Icebergs’ Loud and Mournful Breakup Songs.” Laskow writes that seven years after the largest iceberg broke off of the Ross Ice Shelf in Antarctica, “the largest remaining chunk floated out into the South Pacific where, in the warmer water, it began to disintegrate.”  And for the next year, “the ocean was noisier than usual.”  Scientists from the National Oceanic and Atmospheric Administration (NOAA) had suspended hydrophones underwater and they “were picking up strange signals.” Interestingly, the scientists “didn’t even know that icebergs made noise,” says Haru Matsumoto, an ocean engineer at NOAA who has studied these sounds.”  But now they do and they measure “the extent to which those sounds contribute to the noise of the ocean,” because “the sounds of ice could help them understand the behavior and breakup of icebergs and ice shelves as the poles warm up.”
