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

This was essentially a drillship with sonar equipment and cameras attached to the end of the drilling pipe. It could lift objects from the seabed using a remote-controlled mechanical claw. The expedition ended in failure when the drilling pipe broke, sending of pipe and $600,000 worth of electronics plunging to the sea bed.

"Titanic" would have been well within the submersible's depth limits,
