![]() These laundry symbols tell you all you need to know about how to do the washing and drying, and bleaching and ironing. Noises heard underwater on Tuesday provide hope that the crew on board Titan are still alive, according to Dr Simon Boxall, a senior lecturer in oceanography at the University of Southampton.The symbols printed on the tags of your garments may seem like they are in a foreign language, but they serve an essential purpose: to keep your clothes looking newer longer. 'Noise gives hope this is still a rescue operation' "It is two-and-a-half miles below the surface. Mr Barton, who was the first Briton to complete a dive to the Titanic wreck, added: "It is a pretty hostile environment. ![]() What we know about the search for the vessel and those on board 'This is how it is going to end' - Scientist recounts trapped Titanic submersible experience over 20 years ago "There's lots of activity down there - marine life, submarine and underwater cabling and in general lots of activity. but I think it needs to be kept in context because the ocean is a very busy place," he told Sky News. ![]() "Tapping is a well known means of emergency communication. "The assets are coming together."ĭik Barton, former vice president of operations with RMS Titanic Inc, the company that owns the salvage rights to the Titanic, said it was important to "not get too ambitious". Titan is a "very small target" and a remote operating vehicle from Canadian offshore vessel Skandi Vinland did not turn up anything after being deployed on Tuesday.īut "over the next few hours, I think we're going to see a significant uplift in capability," Mr Parry added. ![]() Image: (L-R) Paul-Henri Nargeolet, Hamish Harding and Stockton Rush. The sounds picked up on sonar could be "spurious" as there is "a lot of noise coming from the ocean", an ex-Navy officer has said.įormer rear admiral Chris Parry said the Titanic itself "makes a lot of noise even as the current shifts through it", and attention should be focused on the area of "likely accident to the vessel itself".Īnalysing the current situation with the now-international rescue effort for the submersible, Mr Parry said there is a "concentrated section of aircraft and support vessels" around the Titanic wreck site. It could be partially submerged, and of course, there's lots of submarine canyons and submarine seamounts. He also added: "It might be nice and flat and it be sitting proudly on top, which would be great. "Let's not give people false hope here, the lack of oxygen is key now - even if they find it, they still need to get to the surface and unbolt it." "The sound could, of course, be coming from something other than the sub," he said. ![]() "Acoustic noise travels far in water so that is both good and bad news - you would still need three of those static buoys to be able to triangulate the sound source to get a position fix."ĭr Keele said the use of sonobuoys - buoys with sonar capabilities - differs from a sonar survey, which uses either a towfish from a surface vessel or an unmanned self-propelled one for deeper waters. He said the fact the noises are half an hour apart is a "great sign" and means they are "unlikely" to be from another submarine or a surface ship propeller. Noises a 'great sign' but could raise 'false hope'ĭr Jamie Pringle, a reader in forensic geosciences at Keele University, said the noises are good news but warned it may give "false hope". Searches continue for the vessel and at least five ships are in the area - with five more thought to be on the way.īut search teams face a frantic race against time to find the submersible - and rescue its five occupants - with experts suggesting that if the vessel is still intact, it would likely have less than 24 hours of oxygen left. Titanic sub search - live: Noise picked up by sonar devices However, the US Coast Guard said on Wednesday that an investigation of the noises using specialist underwater equipment had so far "yielded negative results". The sounds were picked up by a Canadian plane using buoys with underwater sonar capabilities while searching for the missing vessel. Underwater noises heard during the frantic search for the missing submersible, Titan, have sparked fresh hopes of finding the missing vessel - but what do experts think? ![]()
