The sonar blip whch was heard by divers was first thought to have been another shipwreck or caused by some aspect of geology and left explorers scratching their heads
The mystery of a ‘sonar blip’ heard during a dive of the Titanic shipwreck was caused by underwater ‘ecosystem’, it has been revealed.
Those exploring the wreck in 1998 heard a strange sonar transmission in the vast North Atlantic Ocean.
It was first thought to have been another shipwreck or caused by some aspect of geology and left explorers scratching their heads.
But researchers have discovered the transmission noise was caused by an underwater ecosystem which had marine life such as sponges, corals, squat lobsters and fish.
