To mark the occasion, Titanic Belfast has laid on a number of events. Titanic's final resting place was discovered almost 400 miles off the coast of Newfoundland, at a depth of 13,000ft on Septemby a team led by American oceanographer Dr Robert Ballard and French diving engineer Jean-Louis Michel. No one has found human remains according to the company that owns the salvage rights.This year marks the 30th anniversary since the watery grave of the Titanic was discovered. When you hit an iceberg the ship below the water will hit the iceberg before the ship above the water line so it would divert it off its course – it’s not like hitting a brick wall head-on. Would Titanic have sunk today?Īnswer: There is no definitive answer but it would probably have sunk anyway. There have been rare occasions when icebergs have drifted as far south as Bermuda (32 degrees north latitude) which is located about 900 mi (1 400 km) east of Charleston South Carolina. Most icebergs have completely melted by the time they reach about 40 degrees latitude (north or south). Often “downhill” means “towards the ocean”. Gravity not only pulls the snow down into the ice it also pulls the ice downhill. This process is very slow and takes a long time. The crushing force of gravity fuses the non-salty snow crystals into a giant slab of non-salty ice known as a glacier. The huge iceberg measures about 1 668 square miles (4 320 square km) in size. The berg broke off from the western side of Antarctica’s Ronne Ice Shelf into the Weddell Sea. An enormous iceberg – named A-76 – is now the biggest iceberg on Earth. Because a ship may steer to avoid a large parent berg it may be in greater danger from undetected growlers or bergy bits drifting nearby. Can an iceberg follow a ship?Īn iceberg is a very large object that can be detected in the open sea both visually and by radar. A: It is risky and there is a chance that the iceberg could collapse and if it does we could die. Q: Cold temperatures 45-metre icebergs one-metre swells this sounds like a dangerous hobby. You can’t use your feet so you have to use your arms to pull yourself up and onto the iceberg. So while the amount of sea water displaced by the iceberg is equal to its weight the melted fresh water will take up a slightly larger volume than the displaced salt water. Why do icebergs not melt in salt water?įresh water of which icebergs are made is less dense than salty sea water. The density of ice is 0.9167–0.9168 g/cm3 at 0 ☌ and standard atmospheric pressure (101 325 Pa) whereas water has a density of 0.9998–0.999863 g/cm3 at the same temperature and pressure. Seawater is slightly denser than ice and this means that the iceberg floats with most of its mass below the surface. The tip of an iceberg which is visible above the waterline is usually only about 1/7 or 1/8 of the mass of an iceberg. The average depth or draught of an iceberg is slightly less than its apparent length above water. Q: How much of an iceberg is below water? A: Almost 90% of an iceberg is under water hence the phrase “tip of the iceberg.” Its maximum width under water is 20-30% larger than you can see at the surface. That the tip of the iceberg is just 11% is a result of a simple calculation. So 89% of a free-floating iceberg is submerged beneath the surface of the ocean we only see 11% of it above the surface of the ocean. What fraction of an iceberg is submerged? Only 1/7 to 1/8 of an iceberg can be seen above water. In fact on average only 1/10th of an iceberg is above the surface of the water. However because the difference in relative density between ice and sea water is small only some of the iceberg floats above the water. Ice has a slightly lower density than seawater so we see ice floating above the surface of oceans. As you can see the convenient definition of the gram gives us a quick way to see how much of a floating substance lies below the surface of fresh water: the fraction is equal to that substance’s mass density in g/cm?. Over 87% of an iceberg’s volume (and mass) is underwater.
