A ship that tried to warn the Titanic of an iceberg on the night it sank has been discovered at the bottom of the Irish Sea by researchers in the U.K.
Researchers at Bangor University in Wales used sonar technology to identify the wreck of the SS Mesaba, a merchant steamship that plunged to the ocean floor in 1918, they announced Tuesday.
A merchant steamship, the Mesaba was crossing the Atlantic the night Titanic sank in April 1912. It sent a warning about iceberg-laden waters via radio to the British passenger ship that was received, but it never filtered through to the Titanic’s captain, the university said.

Hours later, the luxury liner’s maiden voyage would end abruptly and claim the lives of more than 1,500 people.
Twenty people died aboard the Mesaba when a German U-boat, U-118, torpedoed and sank it, according to wreckage database Wrecksite.eu.
Bangor University researchers positively identified the wreckage for the first time, the university said, cross-referencing wreckage data from government and other databases. It was one of 273 shipwrecks strewn across 7,500 square miles of the Irish Sea, according to the university.
