After eight decades at the bottom of the Labrador Sea, the Terra Nova ship now bears little resemblance to its former self when it transported renowned British explorer Robert Falcon Scott to the South Pole. Described as a wreck in a deteriorating state yet intriguing due to its condition, co-chief scientist David Mearns expressed his fascination during the Canadian-led expedition aimed at documenting the vessel.
In 2012, Mearns participated in the discovery of the ship off the coast of Greenland, but the recent scientific mission marks the first comprehensive effort to capture detailed imagery. This expedition, led by the Royal Canadian Geographical Society, is utilizing remotely operated vehicles (ROVs) and an underwater submersible to investigate the second shipwreck, Terra Nova, following their examination of the Quest, the ship that carried Sir Ernest Shackleton on his final Antarctic voyage.
Recently, the team on board the research ship Atlantis employed an ROV to map the Terra Nova wreck, which was launched in 1884 before Scott’s ill-fated expedition in 1910. Resting beneath 170 meters of water, approximately 30 kilometers south of Greenland since its sinking in 1943, the ship’s double wheels, used for steering the 57-meter sail and steam vessel, remain distinctly visible. Notable features such as the rudder, boilers, and steam winches are also discernible.
Cutting-edge technology developed by Voyis, based in Waterloo, Ontario, is facilitating the creation of three-dimensional images of the wreck, going beyond simple imaging and video capture to comprehensive ship mapping. Marine biologist Kirstin Meyer-Kaiser emphasized the significance of the 3D model, enabling a complete contextual understanding that enhances the scientific value and provides a detailed historical snapshot for future research.
Co-chief scientist Dwight Coleman, director of ocean imaging at the Woods Hole Oceanographic Institution, highlighted the advancement in technology, eliminating the need for manual stitching of numerous photos for a comprehensive view. The expedition’s focus on in-depth study of northern shipwrecks is filling crucial knowledge gaps, with Coleman emphasizing the unique opportunity presented by the advanced camera system deployed during this mission.
Meyer-Kaiser’s research delves into the marine life that has colonized the Terra Nova wreck post-human abandonment, creating a thriving ecosystem compared to the barren seafloor around it. She aims to understand the impact of human-made structures like shipwrecks on marine environments, providing insights into the consequences of introducing new elements into the ocean.
Royal Canadian Geographical Society president John Geiger, leading the expedition, described the exploration of Terra Nova and Quest as a full-circle moment, honoring these vessels as pioneering exploration vehicles of their time. Over a century after Scott and Shackleton’s historic expeditions, their legacies are being meticulously documented using state-of-the-art ocean technology, bridging past exploration with modern scientific advancements.
