Argentine navy lost contact with sub [UPDATE: SUB FOUND]

I would imagine the batteries nowadays would be sealed.

Argentina's navy says fresh noises are not from missing submarine

Argentina’s navy has said sounds detected from the bottom of the ocean are not from the submarine which has been missing in rough seas for five days with 44 crew on board.

Spokesman Enrique Balbi said “a biological source” was behind the noises which were picked up by two Argentinian navy ships searching for ARA San Juan and by sonar buoys dropped by a US P8 surveillance plane.

The navy has also revealed the submarine’s last communication, on Wednesday, was to report a mechanical breakdown related to its batteries. Captain Gabriel Galeazzi, who runs the naval base in Mar del Plata, which was the submarine’s destination, said mechanical problems were not uncommon and rarely posed a risk.

Sadly, I think you may well be right.

Still praying.

I had hope that they may be found the sub then they heard tools getting banged on the hull. But now I have little faith now. One thing good is the weather is clearing up a bit.
Its still unclear to me how much the sub still has Oxygen left.

As of yesterday I believe it was stated 2 days of O2 left. Horrible situation.

And I assume that is a guess considering how little they know about the series of events.

I would believe so, yes.

Articles I have been reading estimate the ocean depth ~230 feet, so if they were unable to surface perhaps they could attempt an emergency escape.

Unlike modern nuclear subs, the 34-year-old, diesel-powered vessel must come up for air every seven days to replenish the cabin’s oxygen supplies and allow its four engines to charge its batteries.

The submarine has emergency canisters that would provide an extra few days of oxygen and remove toxic carbon dioxide, but there is a possibility that it may not be functioning because the vessel is out of power.

Frank Owen, from the Submarine Institute of Australia, told news.com.au that the crew could well be waiting underwater for their chance to surface.
“We know it’s been really rough, so even though the Argentinian navy protocol is to surface, it makes no sense with 6-8m waves to be sitting on the surface,” he said.

“If I was in that situation, I would be sitting on the bottom and waiting, doing everything I could to slow down my metabolism and eke out the life support mechanisms, reduce oxygen use and CO2 creation.”

HOPEFULLY GOOD NEWS!!!!

Missing Argentine submarine 'is located by US Navy and a new sonar signal heard' as rescuers race to the spot with oxygen due to run out imminently

Nothing news ?

[GoldenRivet]

Ive been doing my best all day to keep up with this, so far, i have found nothing since the article about possibly locating the submarine "hot spot" on the sea floor.

[GoldenRivet]

This information is at least 3 or 4 hours old

http://www.dailymail.co.uk/news/arti...submarine.html

Hopes of finding the missing Argentine submarine and its crew of 44 alive were all but dashed on Wednesday.

Early this morning, search teams grew optimistic when the U.S. Navy picked up a 'heat stain' from a metallic object 230 feet before the ocean surface, near where the submarine disappeared in the South Atlantic.

But the heat stain was investigated and turned out not to be the submarine, which was due to run out of oxygen this morning.

'There hasn’t been a trace,' Argentine Navy spokesman Enrique Blabi said Wednesday. 'We’re considering three scenarios: the submarine is above the surface with its engines running, adrift at sea without propulsion or submerged on the bottom of the ocean.'

Hopefully they're adrift. We send enough USN vessels there somebody will eventually run into it, probably literally.

resources are being diverted to the location of an "acoustic anomaly" which was recorded on 15 NOV 2017 approximately 30 nm from the last reported position of the San Juan, which, Coincidentally, the last contact from the San Juan took place on that same date.

The area had previously been searched in poor weather conditions and produced no results.

of interest is the Acoustic Anomaly - which has been devoured by the educated ears of those who listen to oceanic sounds all the time and make - often conclusive - determinations as to what the source of the sounds are. In this case however, the sonar analysts did not call the anomaly an "explosion" but rather a non-biologic, non-seismic sound, unusual, and not something normally produced as part of regular oceanic noises. They did say that they were unable to determine what the sound was exactly, but had ruled out biologic or natural sources.

I would be willing to bet, that what the recordings captured is actually the sound of whatever catastrophe befell the San Juan
