No One Knows What Made This Ocean Sound | The Bloop

What is the Bloop sound? In 1997, the U.S. Navy and NOAA — the National Oceanic and Atmospheric Administration — picked up a sound deep in the Pacific Ocean. It was louder than a blue whale, traveled across thousands of kilometers, and had a signature never heard before. They called it “The Bloop.” Some said it was cracking ice. Others believed it was something alive. But no known creature could have made it. Then… the sound disappeared. Years later, another unexplained sound emerged: the Upsweep — long, rising tones that continue to this day. Subscribe to Histronomy for more real mysteries from Earth, space, and history.
