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 previously unseen pieces of wreckage, and led to the documentary "Titanic's Final Moments: Missing Pieces". RMS Titanic Inc. mounted further expeditions to "Titanic" in 2004 and 2010, when the first comprehensive map of the entire debris field was produced. Two autonomous underwater vehicles – torpedo-shaped robots – repeatedly ran backwards and forwards across the debris field, taking sonar scans and over 130,000 high-resolution images. This enabled a detailed photomosaic of the debris field to be created for the first time, giving scientists a much clearer view of the dynamics of the ship's sinking. The expedition encountered difficulties: several hurricanes passed
