Can Underwater Sound Signals Solve Aviation’s Greatest Mystery?
.Controlled explosionsTo help resolve the debate about the detectability of the acoustic signal from MH370, a practical approach could be to conduct controlled explosions along the seventh arc, similar to those done for the ARA San Juan submarine.On November 15 2017 the ARA San Juan, operated by the Argentine Navy, went missing during an exercise mission. A few hours later an unusual signal was recorded by CTBTO stations. To help with the search, an air-dropped calibration grenade drop was conducted two weeks later near the last known location.The calibration grenade, which was also recorded at the CTBTO
Ocean Infinity’s Hunt for the Submarine San Juan
,” says Oliver Plunkett, Ocean Infinity’s CEO. The ship had a host of experts to help in the hunt, including members of the Argentinian Navy, the UK’s Royal Navy, via the UK Ambassador in Buenos Aires, and the US Navy's Supervisor of Salvage and Diving. Three officers of the Argentine Navy and four family members of the crew of the San Juan also joined Seabed Constructor to observe the search operation. The pressure was on.After the initial search, the AUVs were re-programmed to fly riverbed formations on the seafloor to detect anomalies. "When look at them [anomalies detected
Argentine Submarine Found After Yearlong Search
The Argentine Navy submarine that went missing a year ago off the country's Atlantic Coast was found by a private company involved in what had been a massive search for the vessel and its 44-member crew, the defense ministry said in a news conference on Saturday.The ARA San Juan submarine was discovered by marine tracking contractor Ocean Infinity, 907 meters (2,975 feet) below the ocean surface. The vessel was found in an underwater canyon with its tail partially "imploded," Argentina's Defense Minister Carlos Aguad said.Given the poor visibility at the site, the ministry said it
US Exits Search for ARA San Juan
submarine A.R.A. San Juan that vanished in the South Atlantic in mid November. The U.S. joined the Argentina-led multinational search efforts within 24 hours of learning of the missing submarine on November 17, and is now drawing down, having twice swept the search areas assigned by the Argentine Navy with advanced sensors. U.S. planning and analytical specialists will continue to support the efforts through data analysis. At its height, U.S. contributions to the search and rescue effort included more than 200 search and rescue personnel, four submersibles, one specialized
Argentina Sticking with Submarine Program despite Disaster
surface vessels,” Lamrani said. However, there have been questions since the San Juan went missing on Nov. 15 over the resources Argentina has devoted to its submarine fleet. Relatives of San Juan crew members have said they suspect training and maintenance was inadequate. The Argentine navy says water likely entered the San Juan’s snorkel, causing a battery short circuit and explosion. This scenario could point to deficiencies in the upkeep of the vessel, which will be examined as part of what Macri promises will be an unflinching investigation. Macri has said the
Unmanned Vehicles Aid Search for Argentine Sub
A fleet of four high-tech unmanned underwater vehicles (UUV) deployed by the U.S. Navy have joined ships and aircraft from more than a half dozen countries to search for an Argentine navy submarine missing with 44 submariners on board in the southern Atlantic. One Bluefin 12D (Deep) UUV and three Iver 580 UUVs operated by the U.S. Navy's recently-established Unmanned Undersea Vehicle Squadron 1, based in Pearl Harbor, Hawaii, have joined in the search for ARA San Juan, last seen on Wednesday, November 15, in the San Jorge Gulf, a few hundred kilometers off the coast of southern Argentina.
