Researchers have now seen the wreck of Quest, the last expedition ship used by Ernest Shackleton, rather than only mapping its sonar outline. A remotely operated vehicle descended almost 400 meters in the Labrador Sea and returned close-up imagery. The July 2026 survey followed the wreck’s discovery two years earlier.
Quest was found by sonar before it was seen
Quest sank in 1962 after ice damaged the vessel during a sealing voyage. A Royal Canadian Geographical Society expedition located it in 2024 using sonar and historical navigation records. The 2026 team returned aboard the research vessel Atlantis with a robotic submersible designed to work far below safe diving depth.
The saved CBC report describes the robot’s first visual survey of Quest nearly 400 meters below the Labrador Sea. Sonar had located the wreck in 2024, but acoustic outlines could not show surfaces, fishing gear or small structural details. The 2026 return converted a target on a screen into an archaeological site visible in close-up.
A remotely operated vehicle reached the wreck
The Royal Canadian Geographical Society announced on July 8 that its expedition had obtained the first close-up images of Quest on the Labrador seafloor. The vehicle sent back video of recognizable structures despite decades of corrosion and marine growth.
Quest was built in Norway in 1917 and later purchased for Shackleton’s final expedition. Shackleton died aboard in South Georgia in January 1922, after which the ship continued under other owners. It sank in May 1962 when ice damaged the hull during a sealing voyage; the crew escaped, leaving the vessel to descend largely intact.
Fishing gear covers parts of the structure
The wreck lies about 390 meters deep, where darkness, cold and pressure rule out ordinary archaeological diving. Pilots control the robot through a tether that carries power, commands and high-bandwidth video. Careful navigation is essential because contact could damage both fragile wreckage and the expensive vehicle.
The remotely operated vehicle was linked to the research ship by a cable carrying power and data. Pilots navigated through darkness using sonar, cameras and precise positioning while the surface vessel held station. At that depth, pressure is about 40 times surface pressure, making a crewed scuba survey impossible and placing every camera movement behind a layer of robotic control.
The ship links two eras of polar exploration
Much of Quest is reportedly draped in abandoned fishing gear. Imagery can help identify snagged lines, assess deterioration and map the surrounding debris field more precisely than sonar alone. Comparison with construction plans and historical photographs may reveal which sections survived the sinking and impact with the seabed.
An Eye on the Arctic report shows fishing gear draped across much of the wreck. Nets and lines can obscure features and continue trapping marine life. Removing them would also risk disturbing fragile structure, so documentation comes before any intervention decision.
Images can answer questions sonar cannot
Quest carried Shackleton on the 1921-22 expedition during which he died in South Georgia, making the ship a bridge between the heroic age of Antarctic exploration and later commercial service. The current expedition treated the wreck as a site for documentation rather than recovery. Its greatest return is a visual record gathered without bringing artifacts to the surface.
Photogrammetry can turn overlapping video frames into a three-dimensional model. Researchers can measure the hull, map the debris field and compare later surveys for deterioration without lifting an artifact. Historical plans and photographs help identify machinery or deck features. Each match adds confidence while preserving uncertainty where corrosion has erased diagnostic shapes.
The Labrador seafloor remains a protected grave site
The expedition approached Quest as cultural heritage rather than salvage. A wreck’s arrangement records how it sank, struck bottom and changed over six decades. Moving objects would break those relationships. High-resolution imagery creates public access and a scientific baseline while leaving the ship in the cold, dark environment that has preserved it since 1962. Marine growth can both conceal and protect metal. Corrosion consumes exposed surfaces, while sediment may cover lower sections and slow oxygen exchange. Fishing gear adds abrasion and tension as currents move it across weakened structure. Repeated imagery could show whether lines are shifting or whether hull sections are collapsing, giving heritage managers evidence for leaving the site untouched or considering narrowly targeted debris removal. Quest also carries stories beyond its famous owner. The 1962 crew’s safe escape, later sealing work and decades as a working ship are part of the wreck’s history. Archaeology can hold those layers together instead of freezing the vessel only in 1922. The first images create a fixed baseline dated to July 2026, allowing every later expedition to measure change against a documented starting point rather than memory or sonar alone.
