The Coast Guard finds wreckage at the bottom of the Atlantic Ocean near the Titanic

Weather of Arabia - The US Coast Guard said that wreckage was found at the bottom of the Atlantic Ocean near the Titanic, in the midst of efforts to search for the missing tourist submarine carrying 5 people.

The Coast Guard post on Twitter did not provide any details, nor did it say whether officials believed the wreckage was connected to the missing submarine "Titan", which was on an expedition to view the wreck of the Titanic.

The Coast Guard said the wreckage was discovered within the search area by a remotely operated underwater robot, and is being assessed.

He also explained that a robot sent by a Canadian ship reached the bottom of the sea, while a French research institute said that a deep diving robot equipped with cameras, lights and arms joined the process.

Searches are still intense with ships and planes in the area where, 100 years ago, the wreckage of the Titanic lay, hoping to find the tourist submarine, which is the size of a small van.

The submarine "Titan" - operated by the company "Ocean Gate Expeditions" in the United States - began diving to the depths at 12:00 GMT on Sunday.

In a remote corner of the North Atlantic, the mini-submarine lost contact with a support vessel on the surface near the end of what should have been just a two-hour dive to the world's most famous shipwreck site.

The company said that the submarine moved with enough air for 96 hours (4 days), which means that the oxygen tanks will most likely run out at 12 GMT today, Thursday.

Experts said how long the air actually lasts depends on various factors such as whether the submarine is still intact and how quiet the occupants are.

Coast Guard officials said underwater noises were detected in the search area on Tuesday and Wednesday.

There are still many hurdles, such as locating the ship, reaching it with rescue equipment, and then bringing it to the surface assuming it is still intact. And all of that has to happen before the passengers' oxygen supply runs out.
