Professor Grant Bigg from the University of Sheffield has used a computer modelling simulation to calculate more about the size and structure of the mega-iceberg which caused the ship disaster in 1912.
The Titanic stood no chance as it made its way from England to the United States – as the 75 million tonne iceberg had been building from snow which fell around 100,000 years previously.
The first snowflake had fallen in southwest Greenland, eventually turning into a cluster of smaller icebergs.
They then began to merge into the monster iceberg which was responsible for one of the most famous disasters in history where 1,517 people lost their lives.
Professor Bigg said: “We have a computer model for calculating the paths of icebergs in any given year.
“We take what we know about ocean currents, then add meteorological readings for that year to calculate prevailing winds.
“Applying those techniques to 1912 points to the iceberg coming from around Qassimiut on Greenland’s southwest coast.”
Professor Bigg will present his findings at the Cambridge science festival.
The news comes just weeks after it was announced an exact replica of the Titanic will set sail in 2018.
While the ship’s first, second and third class cabins will be faithful reproductions of the original, a spokesman for mining tycoon Palmer’s Blue Star Line said it would be updated with a full complement of modern technology.
James McDonald, the firm’s marketing director, said: “The new Titanic will of course have modern evacuation procedures, satellite controls, digital navigation and radar systems and all those things you’d expect on a 21st century ship.”
