Scientist Theorises What’s Creating Titanic Sub’s Sonar ‘Banging Sounds’


A scientist has put forth a theory regarding the mysterious sonar “banging sounds” heard near the Titanic sub, shedding light on the possible source of these noises following the vessel’s disappearance.

The OceanGate submersible vanished during its journey to the Titanic wreckage, and the company confirmed that five crew members onboard were missing.

The search and rescue teams have been facing challenges in locating the craft, as the Titanic site itself rests on the ocean floor at a depth of approximately 12,500 feet (3,800 meters), making access difficult even with advanced submersibles.

Earlier this week, a leaked memo revealed that a Canadian aircraft, involved in the search and equipped with specialized sonobuoys for sonar detection, had detected a banging sound near the last known position of the missing submarine.

The Department of Homeland Security email stated that the P8 Poseidon aircraft, with underwater detection capabilities, reported a contact in close proximity to the distress position.

The email also mentioned that the P8 picked up banging sounds in the area every 30 minutes. Four hours later, additional sonar equipment was deployed, and the banging sounds persisted.

Officials have been unable to confirm the origin of the sounds or even determine if they indeed came from the submarine.

Dr. Michael Guillen, a scientist and journalist who visited the Titanic wreck 23 years ago in a submersible and faced his own perilous situation when the vessel became stuck in one of the Titanic’s propellers, shared his thoughts on the nature of the noises.

Speaking on Good Morning Britain, Guillen expressed his emotional connection to the current situation, stating that he felt a “special kindred spirit with these poor souls who are down there.”

He went on to explain the communication methods used by underwater craft, drawing a comparison to his own experience, saying, “Communication from a submersible like that is done with hydrophones to the mother ship, the research ship. Electromagnetic waves and radio waves do not propagate well in the ocean due to its salinity and ionic nature.” Guillen continued, likening the communication process to the principle of two tin cans connected by a string, where acoustics play a vital role.

“If indeed their hydrophone failed so early in the mission, less than two hours down, which means they never even reached the ocean floor, then at the very least, they could simply take their cups and bang on the side of the sub,” Guillen proposed. “That’s what I would do if I were down there, and I’m sure the pilot would recommend it to everyone. With five people inside, they could create a significant racket by tapping on the interior of the sub.”

As the search for the missing submarine continues and the mystery of the banging sounds persists, Dr. Guillen’s insights provide a glimpse into the potential ways the crew members could signal their presence and attempt to attract attention in the depths of the ocean.
