🌎 The "Bloop" is one of the loudest underwater sounds ever recorded. Detected by NOAA hydrophones in 1997, this low-frequency noise was picked up over 5,000 kilometers apart. Scientists later identified melting icebergs as the likely source, not a sea creature or submarine volcano. ✨

🌎 Mysterious low-frequency sounds known as "The Upsweep" have been picked up by underwater microphones in the Pacific Ocean since 1991. This persistent sound rises and falls in pitch, lasts several seconds, and is strongest in spring and autumn. Its source remains unidentified, but some researchers suggest volcanic activity near the origin point may be involved. ✨
