Antarctic scientists seeking to locate the wreck of Sir Ernest Shackleton's lost ship, the Endurance, have arrived at the search site.
The team broke through thick pack-ice on Sunday to reach the vessel's last known position in the Weddell Sea.
Robotic submersibles will now spend the next few days scouring the ocean floor for the maritime icon.
Shackleton and his crew had to abandon Endurance in 1915 when it was crushed by sea-ice and sank in 3,000m of water.
Their escape across the frozen floes on foot and in lifeboats is an extraordinary story that has resonated down the years - and makes the wooden polar yacht perhaps the most sought-after of all undiscovered wrecks.
