Undersea explorer company OceanGate Expeditions has released a stunning video showing Titanic as it has never been seen before – in 8K.

The crew captured the high-resolution footage earlier this year, exposing an astonishing level of detail and colours of the wreckage of the ship.

The footage provides scenes of Titanic's renowned bow, the portside anchor, hull number one, an enormous anchor chain (each link weighs approximately 200 pounds or nearly 91kg), the number one cargo hold, and solid bronze capstans.

The bow of Titanic is also seen in remarkable detail.

"The amazing detail in the 8k footage will help our team of scientists and maritime archaeologists characterize the decay of the Titanic more precisely as we capture new footage in 2023 and beyond," says Stockton Rush, President, OceanGate Expeditions.

"In comparing footage and images from 2021, we do see slight changes in certain areas of the wreck. Our science team will be reviewing the 8k, 4k, and other footage captured during the 2022 Titanic Expedition for any changes.

"Having experts aboard the Titan submersible when we dive allows them to assess the shipwreck through direct observation, guide our exploration of different features of the wreck, and continue their study using the imagery," continues Rush.

The footage is expected to assist in determining the rate of decay for the Titanic as future expeditions capture new footage that can be compared year after year.

With the help of scientists, the video will also support the identification of species that are observed on and around the Titanic and archaeologists will be able to document elements of the wreck and debris field in greater detail.
