Mystery of lost Argentine submarine ends a year later

After a year since 44 Argentine sailors vanished aboard a submarine, the wreckage was found. 
                                 
 “If we had a speck of hope, now there is none left,” said Gisela Polo, the sister of Esteban   Alejandro Polo, 32, one of the sailors who died. “We’ve seen the images. They described the depth where it was found. It makes no sense to keep talking about him in the present tense as if he were still alive.”

Ocean Infinity, a Houston-based ocean-mapping company hired a few months ago, found the submarine nearly 270 nautical miles from the port of Comodoro Rivadavia in Chubut Province and about 3,000 feet under water. The company used unmanned, robotic devices to find it.

Argentina’s government signed a contract with Ocean Infinity that guaranteed the company $7.5 million if it found the submarine. The deal came after many crew members’ relatives accused the government of abandoning the search. Dozens of them set up a makeshift camp outside the presidential palace in Buenos Aires for 52, demanding that a private company be hired to look for the submarine.

The submarine was found in an area that was searched intensively and is filled with canyons and that became a focal point after the Vienna-based Comprehensive Nuclear-Test-Ban Treaty Organization, which has sensors around the globe to monitor nuclear tests, recorded an incident deep in the ocean that was consistent with an explosion.

 “This is the area where we had assigned 90 percent of probability for it to be located,” said Vice Adm. José Luis Villán, the head of the Argentine navy. “All the navies looked in this area but absent the technology that Ocean Infity, we had not found it,” Mr. Villán said.

The Norwegian-flagged Seabed Constructor vessel operated by Ocean Infinity was scheduled to leave the coast of Argentina on Nov. 15, as the 60-day search contract was up and the crew was scheduled to head to South Africa in preparation for its next mission, said Oliver Plunkett, C.E.O. of Ocean Infinity. The company wanted to return in February to continue the search. But a member of the team found something worth postponing the departure by a few days so as to inspect more  closely.

It was the San Juan.

 “The remarkable thing about it, it was literally the last thing we were going to do,” Mr. Plunkett said. “It is a truly unbelievable moment, in the last hour on the last day.”
Many relatives of the victims received the news in Mar del Plata, a port city where they had already gathered in the last few days to commemorate the one-year anniversary of the disappearance.

Some relatives said the news, although painful, brought a measure of closure.

 “I had already assumed he died,” said María Itatí Leguizamón, the 33-year-old wife of Germán Oscar Suárez, a radar operator on the vessel who was 29 when the San Juan vanished. “But I couldn’t help it. There was a part of me that kept holding on to the hope that he could still be alive. But now I know for sure and I can mourn.

 “It’s strange how I feel such a mixture of happiness that they found it but also immense sadness. I just can’t describe it,” she said.

Ocean Infinity began its search on Sept. 7. Three naval officers and four relatives of crew members accompanied Ocean Infinity personnel aboard the ship. It involved “technology never before used during the localization of a submarine,” the navy said at the time.

The company would deploy “Autonomous Underwater Vehicles,” which are unmanned, robotic devices equipped with sonar and high-definition cameras that can function to a depth of almost 20,000 feet.

Ocean Infinity said Saturday that the wreckage of the San Juan was found  by five such vehicles. The devices were operated by 60 crew members on board the Seabed Constructor.

 “Our thoughts are with the many families affected by this terrible tragedy,” Ocean Infinity’s C.E.O., Oliver Plunkett, said. “We sincerely hope that locating the resting place of the ARA San Juan will be of some comfort to them at what must be a profoundly difficult time.”

 Mr. Plunkett said he hoped the “work will lead to their questions being answered and lessons learned which help to prevent anything similar from happening again.”
