Strange sound from the bottom of the Pacific Ocean.  It was suspected of being from an undiscovered sea creature

In the summer of 1997, scientists recorded a strange, loud sound coming from an area west of the southern coast of Chile. They called him “Blob”.

While searching for underwater volcanoes, researchers’ hydrophones from the National Oceanic and Atmospheric Administration (NOAA) recorded a very loud, low-frequency sound. Underwater microphones, originally developed by the US Navy, were located in the Pacific Ocean, approximately 4,000 kilometers away. kilometers.

The sound, which lasted about a minute, was one of the loudest underwater sounds ever recorded. Below is a recording of this sound sped up 16 times:

Over the years, theories have multiplied about the origin of the mysterious sound from the ocean.

However, the question of where these loud noises came from remained unanswered for years.

It wasn’t until 2005, when the National Oceanic and Atmospheric Administration (NOAA) began researching the Antarctic acoustics off the coast of South America, that scientists began to understand the origin of the “bloop.”

Robert Dziak, of NOAA’s Pacific Marine Laboratory, told Insider via email that in 2011 — after collecting all the data — the agency finally clarified the origin of the “bloop.”
