More than a thousand feet beneath the Labrador Sea, the darkness gave way to a bow. For the scientists watching from a submersible, it was the first close look anyone had ever had at the Quest, the last ship of the Antarctic explorer Ernest Shackleton — a moment its expedition leader called simply "moving."
The dive was part of an expedition by the Royal Canadian Geographical Society (RCGS) and the Woods Hole Oceanographic Institution (WHOI) to document two of the most storied vessels of polar exploration's "heroic age." Besides the Quest, the team surveyed the Terra Nova, the ship that carried Robert Falcon Scott toward the South Pole in 1910. Rather than simply photograph the wrecks, the researchers set out to preserve them: using stereo cameras, lasers and a technique called photogrammetry, they stitched thousands of overlapping images into highly detailed three-dimensional "digital twins."
A record that outlasts the wreck
The Quest holds a particular place in the story. Shackleton died aboard the ship in 1922, and it sank decades later, in 1962; the RCGS located the wreck in 2024, but only as a faint sonar shadow. This return trip — with WHOI's Falcon remotely operated vehicle and the storied submersible Alvin, the first crewed sub to reach the Titanic, forty years ago — brought it into sharp focus for the first time. Much of the ship survives: the bow, the deck and some portholes remain, now colonized by pink corals and circled by cod, redfish and wolffish.
For expedition leader John Geiger, the RCGS chief executive, the work marks what he described as a "golden era" for investigating shipwrecks, as imaging technology finally reaches places humans can barely go. The digital models will let researchers — and the public — study the vessels in detail without disturbing them, freezing in data a snapshot of ships that the deep sea will, in time, slowly reclaim.
