The search for the submarine is in full progress with the searches continuing and on a larger scale, the Authorities to carefully examine the underwater sounds they detected in the Atlantic Ocean both yesterday and today Wednesday while at the same time the oxygen inside the submarine lasts less than 20 hours.

At the moment, the investigations around the area where the noises were detected “gave negative results”, said Capt. Jamie Frederick, of the US Coast Guard, in a press conference he gave to inform reporters about the progress of the investigations.

“We don’t know what it is”he said, adding that ROV equipment has been brought in to look for where the sounds were coming from, and data from the Canadian aircraft that first detected the noises has been shared with experts from the US Navy.

This data will “to be considered in future search plans”he said emphasizing that so far the data that has been studied is “unclear”.

“The search area is twice the size of Connecticut”

Captain Frederick also said that the search is continuing to expand. The surface search for the missing submarine is now “about twice the size of Connecticut and up to two and a half miles deep.”

He said rescuers have expanded the search area and are expanding more as time goes on.

He noted that researchers should take into account the “ever-changing weather conditions» during their operation.

The survey site is 900 miles off the coast of Cape Cod and 400 miles southeast of St. John’s, which he said makes “difficult to rapidly mobilize large amounts of equipment”.

Elaborating on the search operation, he said that five vessels are currently searching the surface of the sea and in the next 24-48 hours it will increase to ten. Also, two robotic ROV systems are participating in the survey and more will be in the area tomorrow morning. Back-to-back flights are conducted by two Canadian P3 aircraft providing a total of 14 hours of continuous coverage with C-130s also participating.

“This is a search and rescue mission, 100 percent. We are in the middle of a search and rescue and will continue to put every available means at our disposal in an effort to find the Titan and its crew members.” he said.

Limited water and food

In addition to the minimal oxygen available to the five passengers of the submarine, water and food are also scarce. Officials said they believed the crew on the submarine had “limited rations” of food and water. Frederick also said available oxygen is “just one piece of data” that rescuers are analyzing.

“We must remain optimistic,” he said.

Carl Hatsfield of the Woods Hole Oceanographic Institution says it is “very hard” to discern what are the sources of the noises heard from the Canadian P3 aircraft. He says they were “multiple references” of noises “and each of those noises is analyzed, tracked, patterned and reported.”

The noises “have been described as clicking noises”, says Hartsfield, but the auditory analysts “they have to put the whole picture together and they have to eliminate possible anthropogenic sources.”

“Oxygen Runs Out Thursday Morning”

The oxygen will run out tomorrow morning, (noon Greek time) states Rear Admiral Monger. He said based on information initially provided by the operator, the submarine had about 96 hours of oxygen when it lost contact with the outside world. “One of the factors that makes it difficult to predict how much oxygen is left is that we don’t know the rate of oxygen consumption per passenger in the submarine,” he said.

He added that the search team is operating under the assumption that they have about 20 hours to find and rescue the submarine, which is tomorrow morning local time.

Difficulty retrieving the submarine

But even if one considers the positive scenario that the submarine is eventually located, recovering it “will be an extremely difficult task,” David Marche, a former U.S. Navy submarine commander, told the CBC.

A successful rescue would require remotely operated vehicles (ROVs) capable of allowing operators on the surface a clear view of the submarine’s location, any obstacles that may be present and where to attach cables capable of lifting it thousands of meters through the water. If the Titan and its five-person crew made it to the Titanic wreck, it would be 3,800 meters (12,500 feet) below the surface on the sea floor – too deep for most ROVs to reach. Only a “small percentage of the world’s submarines operate this deep,” Marquet said.
