The United States Coast Guard claims more sounds have been detected while searching for the missing submersible that went on a dive to explore the Titanic wreck site. Captain Jamie Fredrick said they did not recognize the sources of the sounds, but they have been taking help from US Navy to analyze those noises. He added, Meanwhile, the rescue team has expanded the search area to twice the size of the US state of Connecticut.

More boats and underwater vehicles are ready to join the rescue team by Thursday to facilitate the search operation. During his press conference in Boston, the captain said a Canadian search plane detected several underwater noises consecutively on Tuesday and Wednesday. Those detections have helped the searchers to focus on a specific area where the noise signals were picked from, but it is still a question of what those sounds were, and underwater rescuers have found nothing in those areas till now.

More boats and underwater vehicles are joining the search team, and rescue operations will resume where the search initially occurred. The overall area under examination was about 26,000 sq Km (10,000 sq Miles). Captain Fredrich is confident about the operation and says you always have hope, and this is a 100% search and rescue operation. Five surface vessels were part of the rescue operation for the missing submarine, and five more would join them in almost a day. Remotely-operated vehicles (ROVs) also participated in the search, and more will become a part by Thursday.

The Submarine May Go Through Short of Oxygen

Captain Fredrick expressed they have been searching the areas where the noise was picked and announced putting more ROVs in the water in the search’s initial spots. Earlier on Wednesday, Rear Admiral John Mauger told a news agency that the missing submarine had oxygen backups for 96 hours, and now the underwater vehicle could have only 20 hours of oxygen left. He added that some factors make it harder to estimate the total remaining oxygen in the vessel, like consumption by each person and the consumption rate.

Here is a list of People on the vessel, which is still missing after going to see Titanic Wreck:

• Hamish Harding, a British businessman
• Paul-Henry Nargeolet, former French Navy diver
• British Pakistani businessman Shahzad Dawood and his son Suleman
• CEO of OceanGate and Captain of the missing submersible, Stockton Rush

Oisin Fanning, who has been previously on a deep sea trip to Titanic Wrech, knows some of those onboard the missing submersible and told that individuals would understand how to consume the oxygen reserves efficiently. He added that they would have gone through a training session before going for the journey and would look for ways to conserve oxygen straightaway.

Director of the Center for Offshore and Remote Medicine and hyperbaric medicine expert at Memorial University in St John’s, Newfoundland, Dr. Kenneth LeDez, expressed that the crew could even survive the shortage of oxygen depending upon their fitness and submersible conditions. Dr. LeDex added the persons on the underwater vessel might be facing severe conditions like cold temperatures, high levels of carbon dioxide, and fall in oxygen levels. A person going through these conditions may lead to unconsciousness. The doctor further expressed that these conditions are not necessarily deadly, and their metabolism might decrease, but the cold would help them survive.
