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 will have devoured fifty per cent of the hull within 200 years. Since "Titanic's" wreck was discovered in 1985, radical changes have been observed in the marine ecosystem around the ship. The 1996 expedition recorded 75 per cent more brittle stars and sea cucumbers than Ballard's 1985 expedition, while crinoids and sea squirts had taken root all over the sea bed. Red krill had appeared and an unknown organism had built numerous nests across the seabed from black pebbles. The amount of rusticles on the ship had increased greatly. Curiously, the same thing had happened over about the same timescale
