Instead of divers, remote-controlled submersible craft would have to be used, but even that poses problems.
For these jobs, Mr Adair used support-and-rescue ships and semi-submersible fire-boats all of his own design.
Other researchers, too, had sightings, including one from a small submersible and another from a Remotely Oerated Vehicle (ROV).
Six years later a Russian submersible was to plant a titanium flag on the seabed 4km below the North Pole.
Pride operates a worldwide fleet of more than 300 oil rigs--both land-based and on deepwater platforms and submersible rigs at sea.

To do so, they developed a submersible fitted with three wide-angle lenses designed to take high resolution images in low light conditions.
All the lights from the submersible were turned off while they waited.
Directional drilling, bits, submersible pumps, pressure pumping, oilfield chemicals (which is about to be huge, as shale wells get frakked)--they do it all.
Controlling your fish remotely is one thing, but utilizing fish sense to dictate the actions of an uncrewed submersible is an entirely different animal.

Take the slippery task of controlling a submersible vehicle, for example.
Scarabeo 9 is a semi-submersible drilling vessel recently built by Yantai Raffles, which will be on contract by Repsol YPF for deepwater exploratory drilling off Cuba.

Its primary business is the ownership and operation of jack-up rigs, tender rigs, semi-submersible rigs and drill ships for operations in shallow, mid- and deepwater areas.
At the same time, a massive Chinese-built semi-submersible oil rig has been dispatched from Singapore to a position off northwest Cuba, about 50 miles from Key West.
He also holds the world-record depth for a solo ocean dive in a submersible, at 3, 000 feet--"People think it's interesting there, but you're just sitting, " he says.
Finally, as the lights from his Deepsea Challenger submersible set the seafloor aglow, Cameron came to rest at one of the most isolated spots on the planet.
She also wrote that while "there really isn't something akin to the FAA governing submersible operations, " her company thinks sub manufacturers should offer pilot training to the owners of machine.
Japanese zoologist Tsunemi Kubodera, who was on board the submersible at the time of the encounter, was able to lure the giant squid with a one-meter (three-foot) -long diamond squid.
The company deployed the sonar on its torpedo-like Bluefin-21 autonomous underwater vehicle and then used a video-equipped remotely operated vehicle owned by Submersible Systems Inc. to inspect any promising radar targets.
He roared past the depths where the wreckage of the Titanic rests (in the Atlantic Ocean), and at around 21, 000 feet (6, 500 m), beyond the reach of any other submersible today.
At these depths, everything must be done with remote-control robots that install the blowout preventers, submersible pumps and other devices to manage the flow of oil and water on the ocean floor.
They are semi-submersible heavy lift ships, which is to say that the ships are designed to be ballasted down so that their main decks go underwater, allowing their cargo to be floated aboard.

Dr Dave Gallo, director of special projects at WHOI, said the next stage would be to work out what other technology might be of use - and whether the submersible could be used again.
The Department of Defense does not have a submersible that can reach 5, 000 feet with the mechanical arm power to do the types of things that BP and other oil companies buy equipment to do.
Locating a ship resting on the floor of the ocean for many decades is somewhat different than finding a submersible to get to that depth and plugging many leaks in a riser pipe and in a blowout preventer.
The momentum is due in part to greater taxonomy efforts, a growing number of researchers involved in describing new species, and new technologies allowing them to access previously unexplored areas (including improved diving gear and remotely operated submersible vehicles).
