To look for the perpetrators of the sabotage at the Nord Stream will be using the "wiretapping" of the sea

The US Navy decided to listen to underwater recordings of the explosions on the Nord Stream 1 and 2 gas pipelines, which were made by Sweden and Denmark, in order to find out the cause of the incident, writes CNN with reference to two sources familiar with the issue.

“We are aware of leaks from the Nord Stream pipelines. We are ready to provide support and assistance in close cooperation with our allies and partners if needed,” said US Navy spokeswoman Capt. Tamara Lawrence.

At the moment, the United States has the most advanced technology for reading “hydroacoustic signatures” – unique underwater sounds. Sound analysis could be a key part of the investigation, adding to what underwater researchers find, the source said. However, satellite images taken days before the explosions are likely to be useless, officials say.

However, when analyzing audio recordings, everything will depend on their quality. What it is is still unclear. But experts from the Swedish National Seismic Network (SNSN) have already handed over seismic records to the US. However, this is not the same as high quality sonar recordings. The analysis to come will build on a vast library of different sounds that are common to submarines, torpedoes, and marine engines.

“They are looking for known signatures of enemy class ships or known signatures associated with an action such as opening a torpedo room. The goal is to determine what caused it. The quality of the data and the type of records previously made in the database will determine the extent to which they can accurately identify this event using sonar signatures,” said Mark Montgomery, Senior Director of the Center for Cyber ​​Technology Innovation at the Defense Democracy Foundation.

Explosions on the Nord Stream 1 and 2 gas pipelines occurred at the end of September. They damaged three of the four lines of gas pipelines. The cause of the damage is still unknown. The EU called the incident “sabotage” and condemned, and Russian President Vladimir Putin blamed the “Anglo-Saxons” for what happened. Danish, Swedish and German authorities are conducting official investigations into the incident.
