underwater noises. On Wednesday, rescue teams said they heard sounds described as “explosions” coming from the seabed, where the Titan submarine disappeared with its five passengers. “Underwater noises”, confirm the US Coast Guard, which allows hope to be restored.
The ship, which was exploring the remains of the Titanic, does not have a GPS or functional radio due to the depth at which it is located. It was a plane that then picked up its sound signals by dropping sonic buoys, as reported by SkyNews.

These large cylinders are deployed once in the water with one part remaining out of the water and another part searching for certain sound waves with its sonar. Sonobuoys have been used extensively by the military since World War II, primarily for detecting enemy submarines, but they have also become a valuable aid in search operations at sea.
They were used, for example, for the crash of Malaysia Airlines Flight 370, which disappeared over the Indian Ocean in 2014, or during the sinking of the Argentine submarine ARA San Juan in 2017.
It remains to be seen if the detected noises really come from a “message” sent by the Titan’s passengers. On this question, scientists remain cautious as the research area is extensive. Especially since the Titanic wreck, where the research is concentrated, can also cause regular sounds of this kind.
