Wreck of the RMS Titanic D. Michael Harris and Jack Grimm had failed to find "Titanic" but their expeditions did succeed in producing fairly detailed mapping of the area in which the ship had sunk. It was clear that the position given in "Titanic"s distress signals was inaccurate, which was a major expedition difficulty because it increased the search area's already-expansive size. Despite the failure of his 1977 expedition, Robert Ballard had not given up hope and devised new technologies and a new search strategy to tackle the problem. The new technology was a system called "Argo / Jason". This consisted of a remotely controlled
Wreck of the RMS Titanic organisms that they found in and around "Titanic". A total of 28 species were observed, including sea anemones, crabs, shrimp, starfish, and rattail fish up to a yard (1 m) long. Much larger creatures have been glimpsed by explorers. Some of "Titanic"s fauna has never been seen anywhere else; James Cameron's 2001 expedition discovered a previously unknown type of sea cucumber, lavender with a glowing row of phosphorescent "portholes" along its side. A newly discovered species of rust-eating bacterium found on the ship has been named "Halomonas titanicae", which has been found to cause rapid decay of the wreck. Henrietta
