Mysterious “Ocean Quack” Solved

For five decades scientists and submariners have reported odd quacking sounds in the Southern Ocean, nicknaming the phenomenon “the bio-duck.” New recordings created by NOAA researchers have attributed the sound to minke whales. The researchers say they’ll be able to use this knowledge to help track the migrations of the minkes, of which little is known, though our guests have found them to be curious enough to approach our Zodiacs around the Antarctic Peninsula. See the BBC story on minke vocalizations, and if you’d like to hear them for yourself, join us in Antarctica next season.
