5. How did Robert Ballard's and Jack Grimm's quests to find the Titanic differ? (compare and contrast)

Explanation:

Unlike Robert Ballard who was limited financially to get the best underwater sea equipment, Jack Grimm was a millionaire at the time and so in 1980 hired scientists who made use of advanced sonar equipment, although they still weren't successful.

Later though in 1985, it is believed Ballard used specialized submersible equipment called Argo. This equipment had cameras, a hand to pick things up, bright lights, and sonar equipment. The mission was successful not just because of the equipment used but as a result of the determination of Robert and his team.
