How old is an iceberg
Scientists estimate the lifespan of an iceberg, from first snowfall on a glacier to final melting in the ocean, to be as long as 3,000 years.
Who saw the first iceberg
Frederick Fleet, one of the two lookouts in the crow's-nest of the Titanic, was the first man to see the iceberg that sank the liner.
Are there still icebergs
A new study comparing observations of large Antarctic icebergs from the 1700s with modern satellite datasets shows the massive icebergs are found in the same areas where they were pinpointed three centuries ago.
How many icebergs form each year
40,000
A: Every year about 40,000 medium- to large-sized icebergs break off, or calve, from Greenland glaciers. Only about 400-800 make it as far south as St. John's, but these numbers can vary greatly from year to year.
Why are icebergs blue
Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears.
Can icebergs break
Large icebergs can also calve and break apart into multiple smaller icebergs, and ice shelves have been known to rapidly collapse and disintegrate into several or even thousands of icebergs (2, 3).
Did the iceberg cut the Titanic
A persistent theory is that the iceberg tore open a 300-foot gash in the side of the 900-foot-long luxury liner. But the ship was lost off Newfoundland in waters some two and a half miles deep, and no author or naval detective was able to resolve the mystery.
Why didn’t Titanic see the iceberg
On April 14, after four days at sea the Titanic collided with a jagged iceberg at 11:40 p.m. Because it was dark that night, and the lookouts in the crow's nest didn't have binoculars with them since they were locked up, they didn't see the iceberg until it was too late.
Is the Titanic iceberg still alive
Based on its trajectory, the iceberg would have eventually melted away when it reached the warm waters of the Gulf Stream approximately two weeks after striking the Titanic. According to reports by survivors, the iceberg was about 50 to 100 feet tall and may have been as much as 400 feet long.
Can ships still hit icebergs
How often do cruise ships hit icebergs While ships might regularly make contact with ice, it's unusual for it to be an issue.
Is the Titanic iceberg still around
The average lifespan of an iceberg in the North Atlantic typically is two to three years from calving to melting. This means the iceberg that sank the Titanic "likely broke off from Greenland in 1910 or 1911, and was gone forever by the end of 1912 or sometime in 1913."
Do icebergs still sink ships
Thanks to radar technology, better education for mariners and iceberg monitoring systems, ship collisions with icebergs are generally avoidable, but the results can still be disastrous when they occur. "These things are very rare. It's one of those risks that are low frequency but high impact.
Is blue ice old
The oldest blue-ice areas may be up to 2.5 million years old and the ice in them can be quite old as well, with ages of several hundred thousand years estimated on the basis of ice flow dynamics and radiometric dating and the development of a horizontal stratigraphy.
Are there black icebergs
Icebergs can be green, blue, yellow or black. The ice can shine like a sapphire or be as murky as a frozen mud puddle. An iceberg's color is determined by how it interacts with light.
How can iceberg destroy Titanic
Number three the damage. So what happened to cause this kind of widespread. Flooding.
Can ice sink a ship
Sea ice is the biggest threat to the Desgagnés cargo ships as they navigate the Arctic, and the most dangerous pieces of ice are virtually undetectable by radar.
How did the Britannic sink
Speed of Sinking…
At 8.12am on 21st November 1916, while steaming in the Aegean Sea HMHS Britannic struck a mine and sadly sunk in only 55 minutes with the loss of 30 lives.
Did the Titanic have a hole in it
Peering through the mud with sound waves, the team found the damage to be astonishingly small — a series of six thin openings across the Titanic's starboard hull.
Why can’t we pick up the Titanic
There are fears that during retrieval, the Titanic wreck would disintegrate into pieces, making it impossible to have something concrete by the time the remains reach the sea surface. There are documented reports that metal-eating bacteria has already consumed most of Titanic's wreckage.
Is the iceberg that Titanic hit still there
Based on its trajectory, the iceberg would have eventually melted away when it reached the warm waters of the Gulf Stream approximately two weeks after striking the Titanic. According to reports by survivors, the iceberg was about 50 to 100 feet tall and may have been as much as 400 feet long.

What is still left of the Titanic
The ship had been split into two pieces some 2,600ft apart, with the stern (the back of the hull) left largely unrecognisable but the bow (the front) remarkably intact.
Did Titanic hit an iceberg
Titanic struck a North Atlantic iceberg at 11:40 PM in the evening of 14 April 1912 at a speed of 20.5 knots (23.6 MPH). The berg scraped along the starboard or right side of the hull below the waterline, slicing open the hull between five of the adjacent watertight compartments.
Where did Titanic hit iceberg
However, only four days into its maiden voyage, the Titanic struck an iceberg near Newfoundland, Canada. The collision damaged the ship and its watertight compartments. With a limited number of lifeboats, many passengers could not escape the ship.
Is the Titanic fully gone
It is unclear how long the Titanic will remain intact at the bottom of the ocean. By one estimate, UNESCO has said it is expected to disappear by 2050. Research expeditions to the site have been ongoing since its discovery, while tourism opportunities are a more fledging — and luxury — opportunity.
