An expedition probing the Titanic wreck has revealed sharp new images of the world’s most tragic shipwreck.

A research team has been relying on a robot pair to click thousands of photographs and hours of video of the wreck, roughly four km below the sea surface.

The high-resolution images include views of the ship’s bow, clearly depicting the railing and anchors, reports the Daily Mail.

The expedition left Newfoundland in Canada earlier this month for the spot in the Atlantic where Titanic sank after colliding with an iceberg in 1912. More than 1,500 passengers and crew perished. It was super luxury liner’s maiden voyage.

Scientists are relying on imaging technology and sonar devices that are being used for the first time on the Titanic wreck.

They are probing nearly a century of sediment in the debris field to seek a full inventory of the ship’s artefacts.

The expedition is a partnership between RMS Titanic Inc., which has exclusive salvage rights to the wreck, and the Woods Hole Oceanographic Institution in Massachusetts, US.

Officials from Expedition Titanic said they are now headed back to Newfoundland because of the rough weather conditions brought on by hurricane Danielle.

The expedition is scheduled to probe a three-by-five-km debris field where hundreds of thousands of artefacts remain scattered.

Expedition officials say they intend to return to finish their work after a delay of a few days.

“Titanic” Director James Cameron has also led teams to the wreck to record the bow and the stern, which separated during the sinking and now lie one-third of a mile apart. RMS Titanic made the last expedition to site in 2004.
