New high-resolution images of the 110-year-old Titanic shipwreck are hoped to help scientists determine the ship's rate of decay.
OceanGate Expeditions, the company behind the mission to capture the images, released the footage of the Titanic, saying it was the "first of its kind".
Video shows the hull of the sunken vessel and "some brand-new details", OceanGate Expeditions and Titanic expert Rory Golden, who has completed multiple dives and has studied the wreck for decades, said.
"I had never seen the name of the anchor maker, Noah Hingley & Sons Ltd., on the portside anchor," he said in a press release.
"It's exciting that, after so many years, we may have discovered a new detail that wasn't as obvious with previous generations of camera technologies."
The Titanic wreck was found near Newfoundland in 1985. The vessel has sat on the ocean floor under 3,800 metres of water since its ill-fated maiden voyage in April 1912.
Early in the new video of the wreck, you can see the crane which was used for deploying the enormous 15-tonne anchor still located on the deck and the shackle that was originally attached to the main mast, which has now collapsed.
The footage also shows the Titanic's renowned bow, the port side anchor, hull number one, and an enormous anchor chain, each link of which weighs nearly 91 kilograms.
The team of scientists and maritime archaeologists said they had already noticed "slight changes in certain areas of the wreck" in comparison to what they saw during last year's expedition, with some of the Titanic's rail rail collapsing and falling away from the ship.
The footage is expected to help determine the Titanic's rate of decay as future expeditions capture new footage that can be compared year after year.
More than 2,000 passengers and crew were on the Titanic for its maiden voyage, but only 706 survived the sinking.
The ocean liner only had lifeboats for 1,178 people.
