On December 19, 2024, scientists reported detecting a mysterious low-frequency sound at Point Nemo, the most remote location on Earth, situated 2,689 kilometers from the nearest land.
This area serves as a dumping ground for defunct spacecraft, including Russia's Mir space station. The sound, known as the "bloop," was first detected by the National Oceanic and Atmospheric Administration (NOAA) in 1997 using hydrophones positioned across the Pacific Ocean.
Remarkably, the sound was so powerful that underwater microphones located 4,800 kilometers away also captured it. Chris Fox from NOAA speculated that marine life, such as whales and dolphins, might produce such sounds. However, the intensity of the "bloop" has led some researchers to consider the possibility of a giant squid or other deep-sea creatures inhabiting the area.
Fox also proposed an alternative explanation, suggesting that the sound may originate from ice calving in Antarctica, as it consistently comes from the southern direction. NOAA has previously recorded similar sounds, which were used to monitor the calving of icebergs, including A53.
The recorded sounds from the summer of 1997 align with seismic activity caused by large ice chunks breaking apart, according to the Pacific Marine Environmental Laboratory.
