ArticleBody:Over 64 years ago, the ocean quacked. Specifically, sailors aboard an Oberon-class submarine in 1960 detected a series of short, odd noises that resembled an agitated waterfowl. But they weren’t the only people to hear the sounds. In the ensuing decades, multiple instances of the strange audio—nicknamed the “Bio-Duck”—were documented, particularly in the waters surrounding Australia and Antarctica, including a soundscape analysis of the South Fiji Basin in 1982.
Focusing on Bio-Duck, however, helped further their understanding of ocean bioacoustics. “As it turned out, we learned something new about sound in the ocean every day as we looked further into the data—it was really an exciting time for us.” In the case of 1982’s Bio-Duck detection, researchers used what’s known as an acoustic antenna, which includes multiple hydrophones towed behind a ship as it trawls the waters.
