The massive search and rescue operation for missing OceanGate Submersible is ongoing across the North Atlantic after a submersible searching for the wreck of Titanic disappeared deep beneath the sea on Sunday. There are five who are aboard.

Researchers on the Polar Prince the mothership of its ship at the surface and lost contact with crew soon following that the Titan started its descent. The oxygen supply is not sufficient available on the Missing OceanGate Submersible. It is believed that oxygen supplies will end by approximately 10:15 GMT (06:00 ET) on Thursday.

The sound of bangs has been observed within the search zone from missing OceanGate Submersible. However, it’s not clear where they’re coming from, or the meaning behind them.

US, Canadian and French agencies have joined forces to find the submersible and tour company OceanGate states it is looking at the possibilities of getting the vessel back in safety. We’ll look at what we’ve learned to date.

A Canadian search plane has detected underwater sounds. Experts from deep sea say it’s difficult to identify the source of these sounds without seeing the information.

However, it’s possible that these could be brief, extremely high-frequency sound waves that are generated within the vessel.
