Iceberg That Sank Titanic Estimated To Be 100,000 Years Old

It's been over 100 years since the sinking of the Titanic, but research is still being done to understand the tragedy. Recently, scientists were able to make some surprising calculations about the iceberg that caused the luxury ship to go down.

According to Grant Bigg with Sheffield University in the U.K., the iceberg is thought to have been around 100,000 years old, reports the SundayTimes.

And while the block measured approximately 400 feet long and protruded 100 feet above the water when the ship crashed into it, the iceberg likely started out being around 1,700 feet long when it began drifting from the Greenland area.

Unusually warm temperatures is one hypothesis for why the breakaway occurred around 1908.

Its time in the water is also believed to have significantly reduced its mass from about 75 metric tons to around 1.5 metric tons.

These findings were made by applying witness accounts and ocean currents from that day to a computer modeling system that can map iceberg paths.

More than 1,500 people were killed when the Titanic sank on April 14, 1912.

The research will be presented at the Cambridge Science Festival.
