Warming world, noisier oceans?
The findings hint that as temperatures increase with global warming, some areas, such as Western Antarctica, could see increased iceberg disintegration, which could in turn make for noisier oceans.
The sound of icebergs shattering can overlap with the sound frequencies of some whale and cetacean calls, which are typically lower than is audible by the human ear, Matsumoto said.
But iceberg noise could not only hinder whales' communication, but also that of fish, said Marie Roch, a computer scientist at San Diego State University, who was not involved in the study.
For instance, some evidence suggests that larval fish use sound to navigate to coral reefs to feed. "If it becomes louder, then it's harder for them to find coral reefs," Roch told LiveScience. (Icebergs in this particular region would probably not affect these species of fish, but those in other regions could potentially affect this process, she said.)
