The Bloop is a mysterious sound that was first detected by the National Oceanic and Atmospheric Administration (NOAA) in 1997.
It was picked up by hydrophones located 5,000 km apart and was loud enough to be heard by multiple sensors over a distance of 3,000 km. The sound lasted for about a minute and was heard several times over the course of a year.
The NOAA has been monitoring the ocean for decades, using hydrophones to detect and record sounds from various sources.
The Bloop is one of the most unusual sounds ever detected by the organization, and it has captured the imagination of people around the world.
While there are many theories about what could have caused the sound, scientists continue to study the data in an effort to uncover the truth.

Discovery and Investigation
In 1997, a sound was detected by hydrophones located over 5,000 kilometers apart in the Pacific Ocean.
The sound was named “The Bloop” due to its distinctive sound profile. Scientists initially thought that the sound was produced by a large sea creature, such as the giant squid.
However, further investigation revealed that the sound was likely of non-biological origin.
Hydrophones are underwater microphones that are used to detect and record sounds in the ocean. The Bloop was detected by the U.S. Navy Sound Surveillance System (SOSUS), which is a network of hydrophones used for underwater surveillance.
The SOSUS hydrophone array was developed during the Cold War to detect Soviet submarines.
Role of NOAA
The National Oceanic and Atmospheric Administration’s (NOAA) Pacific Marine Environmental Laboratory (PMEL) played a crucial role in investigating The Bloop.
The Acoustics Program at PMEL is responsible for developing and maintaining the acoustic monitoring project, which includes the deployment of autonomous hydrophone arrays in the ocean.
NOAA scientists analyzed The Bloop sound and concluded that it was likely produced by icequakes, which are seismic events caused by the fracturing of ice in the ocean.
The sound profile of The Bloop was consistent with other icequake recordings.
Theories and Explanations
There have been several theories and explanations proposed to unravel the mystery behind the Bloop, a mysterious ultra-low frequency underwater sound recorded in 1997.
While some theories have been debunked, others continue to intrigue scientists and enthusiasts alike.
Icequake Theory
One of the most widely accepted explanations for the Bloop is the Icequake theory. According to this theory, the Bloop was caused by the cracking of an ice shelf or sea ice.
When large masses of ice break apart, they can produce sounds that travel long distances underwater.
The sound waves generated by these ice movements can be picked up by hydrophones and recorded as the Bloop.
Animal Origin Hypothesis
Another theory that gained traction was the Animal Origin Hypothesis. Some researchers believed that the Bloop was produced by a large, yet undiscovered, marine animal.
This theory was fueled by the spectrogram of the sound, which resembled that of a living creature.
However, further analysis of the sound waves revealed that they were consistent with those produced by icequakes.
Man-Made Sound Theory
The Man-Made Sound theory suggests that the Bloop was a result of human activity, such as military exercises or the use of underwater explosives.
However, this theory was also debunked as there were no reports of any such activities in the area where the Bloop was recorded.
Impact and Influence
The Bloop has gained significant attention in popular culture, particularly in the realms of science fiction and horror. It has been featured in various podcasts and television shows, including the popular science podcast Radiolab.
The mysterious and unexplained nature of the sound has captured the imagination of many, leading to various theories and speculations about its origin and meaning.
Scientific Significance
The Bloop has also been of great scientific significance. The sound was first detected by the US National Oceanic and Atmospheric Administration (NOAA) in 1997 and was initially thought to be of biological origin.
However, further analysis revealed that the sound was likely produced by the cracking of icebergs in the Southern Ocean.
The Bloop has been used as an example of the impact of climate change on the world’s oceans. The cracking of icebergs, which produces the sound, is a result of melting ice due to rising temperatures.
The Bloop serves as a reminder of the need to address the issue of climate change and its impact on our planet.
The Bloop has also been used as a tool for scientific research. Its unique sound signature has been analyzed by scientists to develop new methods for detecting and tracking underwater sounds.
This has led to advancements in underwater acoustics and has helped scientists better understand the complex underwater environment.

Frequently Asked Questions
What caused the mysterious sound known as ‘the bloop’?
‘The bloop’ was a mysterious underwater sound that was detected by the National Oceanic and Atmospheric Administration (NOAA) in 1997. The origin of the sound has been a topic of debate ever since.
Some believe that the sound was caused by a massive creature, while others think that it was simply a natural phenomenon.
Has ‘the bloop’ ever been heard again?
Since its initial detection in 1997, ‘the bloop’ has not been heard again. Despite numerous attempts to locate the source of the sound, scientists have been unable to determine its origin.
What is the scientific explanation for ‘the bloop’?
According to NOAA, the most likely explanation for ‘the bloop’ is that it was caused by an icequake. An icequake is a seismic event that occurs when a glacier or ice sheet shifts and creates a large amount of pressure. This pressure can create a sound that is similar to an earthquake.
Could ‘the bloop’ have been caused by a living creature?
While some have speculated that ‘the bloop’ was caused by a massive creature, there is no scientific evidence to support this theory. Most scientists believe that the sound was caused by a natural phenomenon.
What impact has ‘the bloop’ had on oceanic research?
‘The bloop’ has had a significant impact on oceanic research, as it has sparked interest in the study of underwater acoustics. Scientists continue to study the sound in an effort to determine its origin and to better understand the underwater environment.
Are there any theories about the origin of ‘the bloop’?
There are many theories about the origin of ‘the bloop’, ranging from natural phenomena to extraterrestrial activity. However, the most widely accepted theory is that the sound was caused by an icequake.
