Captain Smiths bathtub in the captains quarters on the wreckage of the RMS Titanic. The Titanic sank on its maiden voyage on 15 April 1912 after hitting an iceberg in the northern Atlantic, leading to the deaths of over 1500 people, including Captain Smith. The wreckage was discovered in 1985 at a depth of around 3.5 kilometres. Stalactite-like formations of iron oxide known as rusticles can be seen growing over most of the pipes in the room. These form when microbes such as Halomonas titanicae bacteria break down the ships iron, and there are concerns that these bacteria will break down the entire shipwreck within 30 years. Photographed by a Mir submersible camera in June 2003.
