The search intensified Thursday for a small submersible lost in the depths of the North Atlantic Ocean as oxygen supplies for the five people trapped inside the vessel was believed to be in its final hours.

Two more remotely operated vehicles dived into the water Thursday morning to join the search for the Titan submersible, according to tweets from the United States Coast Guard. An ROV deployed by the Canadian vessel Horizon Arctic had reached the ocean floor at the site of the Titanic shipwreck to look for the Titan, and another from the French vessel L'Atalante was en route.

The Titan lost contact with surface vessels on Sunday as it was diving to reach the famous wreck. There were five people on board including Stockton Rush, chief executive officer of OceanGate Expeditions, the company that owns and operates the Titan.

Officials have said the minivan-size submersible has an air supply that can last four days, which means the supply could run out on Thursday.

The search is being carried out about 700 kilometres off the southeast coast of Newfoundland, near a renowned fishing area known as the Grand Banks. Winds in the area Thursday morning were gusting up to 30 kilometres an hour, and swells were more than a metre high, the coast guard said.

American authorities have said "banging sounds" had been detected in the search area, though the cause remains unclear.
