A grim animation has shed fresh light on just how deep the missing Titanic-bound submersible could be below the surface — as rescue crews raced against time Wednesday to find the five passengers onboard before their air supply runs out.

The video, created by Spanish company MetaBallStudios, shows the gradual descent to the deepest part of the ocean — passing by the century-old wreck of the Titanic, which lies on the seabed at a depth of about 12,500 feet.

On the way down, the 3D animated clip shows popular landmarks — including the iconic Statue of Liberty — to show the full depth of the ocean in perspective.

The footage shows Lady Liberty roughly 305 feet below the surface. It’s followed by the Eiffel Tower at 1,000 feet and the world’s tallest building, the Burj Khalifa in Dubai, at 2,700 feet.

Eventually, the animation reaches the Titanic wreckage and continues down to the deepest known point of the seabed — known as the Challenger Deep — at nearly 36,000 feet.

The haunting clip, originally posted in late 2021, resurfaced on Twitter after the tourist submersible went missing in the North Atlantic on Sunday on its descent to the historic ocean liner wreckage.

The US Coast Guard said Wednesday it was bringing in more ships and underwater vessels to search for the submersible after detecting unidentified underwater sounds, including banging noises.

They released an image of one of the ships scouring the area for any signs of the submersible.

Coast Guard Captain Jamie Frederick said at a press conference that analysis of the noises has been “inconclusive.”

“When you’re in the middle of a search-and-rescue case, you always have hope,” he said. “With respect to the noises specifically, we don’t know what they are, to be frank with you.”

Teams from the United States, Canada and France using airplanes and ships have already trawled more than 10,000 square miles of open sea, roughly the size of Massachusetts.

The 22-foot vessel, which is operated by US-based OceanGate Expeditions, is estimated to have as little as a day’s worth of oxygen left if it is still functioning.

Those aboard the submersible include British billionaire and adventurer Hamish Harding, 58, and Pakistani-born businessman Shahzada Dawood, 48, with his 19-year-old son Suleman, who are both British citizens.

French explorer Paul-Henri Nargeolet, 77, and Stockton Rush, founder and chief executive of OceanGate Expeditions, were also reported to be on board.
