What was the Julia noise?
Iceberg Grounding on Seafloor (Julia) This sound was recorded on March 1, 1999 on the eastern equatorial Pacific autonomous hydrophone array. The most likely source of the sound formerly known as “Julia” is a large iceberg that has run aground off Antarctica.
What is Julia underwater?
“Julia” Loud creepy sound from the ocean. Julia is a sound recorded on March 1, 1999, by NOAA. It was recorded by the equatorial hydrophone array and lasted for 15 seconds. Similar to the Bloop sound, NOAA researchers say that it is the sound of a large iceberg running into the seafloor.
Is Upsweep real?
Upsweep is an unidentified sound detected on the American NOAA’s equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991.
What is the Bloop monster?
The Bloop was the sound of an icequake—an iceberg cracking and breaking away from an Antarctic glacier! With global warming, more and more icequakes occur annually, breaking off glaciers, cracking and eventually melting into the ocean.
What made the Upsweep sound?
Spectrogram of the unexplained sound known as Upsweep. Upsweep has been around since 1991, and according to NOAA the origin of the sound is unresolved. The most likely explanation for the sound offered thus far is that it’s the result of underwater volcanic activity.
Does the ocean record sounds?
Sound recordings made on the beach or by the sea tend to have many layers and endless variations. Ocean Sounds contains sound recordings of waves on the beach as well as sounds and recordings of rocky seashores, cliffs, sand and gravel beaches, and open water (in the middle of the ocean).
Does the bloop still exist?
Dziak explained to us the NOAA’s findings, and confirmed that “the frequency and time-duration characteristics of the Bloop signal are consistent, and essentially identical, to icequake signals we have recorded off Antarctica”.
Are sea monsters real?
Hundreds of years ago, European sailors told of a sea monster called the kraken that could toss ships into the air with its many long arms. Today we know sea monsters aren’t real–but a living sea animal, the giant squid, has 10 arms and can grow longer than a school bus.
What are ocean sounds called?
ambient noise
The background sound in the ocean is called ambient noise. The primary sources of ambient noise can be categorized by the frequency of the sound. In the frequency range of 20-500 Hz, ambient noise is primarily due to noise generated by distant shipping.
How does Skyquake happen?
Their origin has not been positively identified. They have been explained as: Coronal mass ejection CMEs often generate shock waves similar to what happens when an aircraft flies at a speed higher than the speed of sound in Earth’s atmosphere (sonic boom).
Where did the Julia sound come from?
The sound was recorded on March 1, 1999 on the Equatorial Pacific Ocean autonomous hydrophone array. The source of the sound is unknown, but is sufficiently loud to be heard over the entire array. The duration is approximately 15 seconds and is severely band limited. The approximate origin is 1999JD60 2218Z near 15S, 98W. Listen to the Julia sound
What is that weird sound coming from the Pacific Ocean?
(Image credit: NOAA) This weird noise, which sounds almost like someone cooing or whining, occurred on March 1, 1999. The eastern equatorial Pacific autonomous array (a network of hydrophones) picked up this strange sound. Like the Bloop, Julia is most likely the sound of ice.
Are there any bloops in the ocean?
No further Bloops have been heard since 1997, although other loud and unexplained sounds have been recorded. This sound was recorded on March 1, 1999 on the Equatorial Pacific Ocean autonomous hydrophone array. The source of the sound is unknown, but is sufficiently loud to be heard over the entire array.
What was the loudest sound ever recorded in the ocean?
Julia was recorded on March 1, 1999, lasted for roughly 15 seconds, and was loud enough to be heard by the entire Equatorial Pacific Ocean hydrophone array. An Antarctic iceberg run aground is the leading suspect for its source.
