The search task was carried out in “remote” areas, as described Monday afternoon by John Mauger, admiral of the United States Coast Guard, the agency leading work on the small, minivan-sized submarines operated by the company. Sea Gate.

So the pressure to find them before they run out of oxygen is added “remote and complicated” regional conditions. Like where Titan disappeared.

“We will do the best we can for every moment in that time,” said Mauger.

Mauger explained that the United States has sent three C-130 aircraft, while Canada has sent other aircraft of the same type, as well as a P-8 submarine, to assist in the search.

The US Coast Guard admiral added that Commercial sailboats are also participating in the quest to cover a wider area.

“On the surface we have a commercial operator already on site,” he explains.

David Concannon, an adviser to OceanGate, told the Associated Press that officials are working to use the US Navy’s remotely operated vehicles to participate in the task.

It’s not that easy. To recover objects in deeper waters, the US Navy relies on what it calls remotely operated vehicles, such as the one used to rescue an F-35 that crashed in the China Sea in early 2022. That is a CURV-21, capable of reaching depths of up to 3.7 miles (about 6,000 meters).

But getting him to that place takes time, and a ship capable of transporting them to the site taking into account the weather conditionsexplained The New York Times.

The area of ​​the Titanic wreckage is about 370 miles (about 600 kilometers) south of Newfoundland, Canada, and ships capable of carrying the Navy’s most powerful underwater drones moved no faster than about 20 miles (32 kilometers) per hour.

Authorities suspect that Titan is in an area about 900 miles east of Cape Cod, Massachusetts, at extraordinary depths: the submarine has the capability to descend to 2.4 miles (about 3,800 meters).

The first difficulty is the darkness of the ocean depths. Sunlight only reaches a depth of one kilometer, so rescuers had to use sonar technology to detect underwater activity to find Titan.

On the surface, the task of the ships and aircraft involved in the search was complicated by the dense fog and waves in the area. Waves reached heights of up to six feet (two meters) in the area.

The second obstacle is the complexity of the seabed which can have several layers.

Chris Parry, a retired British Navy rear admiral, told Sky News the rescue was “a very difficult operation”.

“The true nature of the ocean floor is very bumpy. The Titanic itself lies in a ditch. There is a lot of debris around. So, to direct sonar technology to the area that you want to search with other submarines will be very difficult,” he said.

To determine where the ship sank, at depths such as the area where Titan disappeared, sonar technology is needed.

Sonar is an acronym for sound, navigation and range, and is a technology that sends pulses of sound waves through water. When they hit an object, they are reflected back to the surface, allowing you to determine how far an object is.

Investigators suspect that the submarine was in a very narrow area at the time of its disappearance.

“In that depth, Sonar search systems must be highly specialized to pass through very tight areas with a high enough frequency to find small submarines,” Jamie Pringle, a forensic geosciences researcher at Keele University, told the BBC.

In many submarines, the air inside is recycled — that is, carbon dioxide is removed and oxygen added — but over time, the ship loses the ability to remove enough carbon dioxide, so the air inside is no longer breathable.

Also, if the Titan’s battery runs out, the heaters that keep the occupants warm will stop working in the middle of icy waters in the depths of the ocean.
