Even after a century beneath the water, the Titanic's bow remains one of the most magnificent and haunting sights in the ocean. However, a new survey of the wreck site has revealed that the railing, made famous by Jack and Rose, has now collapsed into rust. Haunting images snapped by underwater robots through the years show the great ship's bow has gradually eroded. Experts say that its metal construction and frequent human visits mean it is only a matter of time before the Titanic collapses. Dr Rodrigo Pacheco-Ruiz, archaeological data manager for HMS Victory and maritime archaeologist from the University of Southampton, told MailOnline: 'The realistic view is that because she's such a big metal object, she won't be there for very long.' Haunting pictures reveal how the Titanic's iconic bow has decayed in the 37 years between 1987 and 2010 Earlier this week, RMS Titanic Inc, the company which holds the salvage rights for the ship, released new images and footage of the sunken liner.

The race against time to find a submersible that disappeared on its way to the Titanic wreckage site entered a new phase of desperation on Thursday morning as the final hours of oxygen possibly left on board the tiny vessel ticked off the clock. The vessel, named Titan, lost communication with tour operators on Sunday while about 700km (435 miles) south of St John's, Newfoundland, during a voyage to the Titanic shipwreck off the coast of Canada. The 6.7-metre-long OceanGate Expeditions vessel began its descent at 8am (12:00 GMT) on Sunday. Considering that it had a 96-hour air supply from the time it is sealed, according to its specifications, the US Coast Guard estimated oxygen in the submersible would have run out at about 10:00 GMT on Thursday. This can vary depending on a few factors, such as whether the sub still has power in the icy depths.

Fox News correspondent Molly Line has more on the search to rescue the five individuals on the Titanic voyage on'Special Report.' BOSTON – Three new vessels arrived "on-scene" in the Atlantic Ocean Wednesday morning to join search and rescue efforts for the missing OceanGate Titan sub as the estimated oxygen supply on board continues to dwindle. The U.S. Coast Guard said the new vessels bring additional tools to scan the ocean floor as they race against the clock to save the five people onboard: OceanGate CEO Stockton Rush, British businessman Hamish Harding, father-and-son Shahzada and Suleman Dawood, who are members of one of Pakistan's wealthiest families, and Paul-Henry Nargeolet, a former French navy officer and leading Titanic expert. "The John Cabot has side-scanning sonar capabilities and is conducting search patterns alongside the Skandi Vinland and the Atlantic Merlin," the Coast Guard said. The John Cabot is a Canadian coast guard vessel, the Atlantic Merlin is a Canadian remotely operated vehicle (ROV), and the Skandi Vinland is a commercial ROV, authorities said.

A necklace'made from the tooth of a megalodon shark' is revealed in new images from the wreckage of RMS Titanic. The stunning artefact – which has not been worn since the ship's sinking in April 1912 – was identified in footage taken last summer by Guernsey-based firm Magellan Ltd. The footage was shot during efforts to capture the first digital scans of the shipwreck, which present the wreck almost as if it's been retrieved from the water. Other objects surrounding the necklace have not been identified, although it appears to be surrounded by small ring-shaped beads. Magellan Ltd, which is working with Atlantic Productions on a documentary about last year's expedition, is prohibited from taking them from the sea floor, however.
