As a (one-time) oceanographer, I was thrilled to read that Shackleton's ship, the Endurance, was finally located on 5th March 2022.
’s 1914 expedition was an attempt to make the first land crossing of Antarctica via the South Pole. However, after Endurance became trapped in pack ice, Shackleton was forced to abandon his ship and take his twenty-eight crew members across the ice to Elephant Island, where they built a makeshift camp. Shackleton himself pressed on with five other men for 800 miles before arriving in South Georgia, from where a rescue was mounted.
The discovery of Endurance was made possible through the use of a hybrid underwater search vehicle from Saab, known as a Sabertooth. This vehicle combines the features of a Remote Operating Vehicle (ROV), which is linked to a ship or other structure on the surface via a tether, and an Autonomous Underwater Vehicle (AUV), which can operate without a link.
Underwater exploration is not the only field in which Sabertooth vehicles operate; they are increasingly being used in the oil and gas industry, for example, undertaking a range of tasks, including undersea inspection, maintenance and repair.
