Time To Go Under: The History of Diving and Submersibles

One of the greatest advances in oceanography is the use of various autonomous and remotely operated underwater vehicles to travel to the ocean depths in search of new discoveries and explorations. However, not everyone thinks the latest developments should replace human diving in manned submersibles. There is an ongoing debate among oceanographers over the type of vehicle that can most effectively make exploration possible.

Some oceanographers argue that remotely operated vehicles (ROVs) are best suited for deep sea exploration. They point out that ROVs can spend more time exploring during a dive because battery power is not being used to run life support systems. Other oceanographers feel that exploration of the ocean depths can only be done effectively by manned submersibles. The ability of humans to react quickly to objects, motions, and colors that may briefly catch their attention is important to those who support manned vehicle exploration. They believe that remotely controlled vehicles could easily miss important discoveries. What do you think?
