November 21, 1915: The Day the Endurance Sank
The men were standing on the ice when she went down. Twenty-eight of them, scattered across a flat white expanse of frozen Weddell Sea, watching the ship that had been their home for fifteen months break apart in slow motion two hundred yards away. The pressure had been working at her hull since October, the pack ice closing on her flanks like jaws. By 21 November 1915 the sea had finally won. The stern lifted out of the floe, the masts snapped forward in a slow forty-five-degree arc, and then the Endurance slid backwards into the dark water and was gone. The ice closed over the place where she had been.
Frank Hurley, the expedition's photographer, captured the final moments on a glass plate. Frank Wild, second-in-command, was standing beside Shackleton. The men were silent. Shackleton, according to Hurley's diary, said only one thing as the masts disappeared: "She's gone, boys." Then he turned to face the camp and the work that came next.
The arithmetic was simple and impossible. Twenty-eight men. Three lifeboats. Approximately a year's worth of supplies on the ice with them. Their position was 68°38'30"S, 52°58'W — roughly 1,200 miles from the nearest inhabited place on Earth, which was a Norwegian whaling station on the island of South Georgia. The Antarctic winter was approaching. The pack ice they were standing on was drifting, slowly, in a direction nobody could be sure of. Nobody on Earth knew they were alive. Nobody would come looking for at least a year. They could not stay where they were because the floe would eventually break up. They could not move because there was nowhere on the continent to go.
Shackleton's response was to issue a single instruction: nothing essential is to be wasted. Personal possessions over two pounds in weight were to be discarded. He himself reached into his coat, took out a gold cigarette case and a handful of sovereigns, and dropped them on the ice. He kept his pipe and a few photographs. The men understood the message. Their job was now to live.
The thesis of the Endurance is the inversion of every other polar disaster. Robert Falcon Scott led five men to the South Pole and lost them all. Sir John Franklin sailed two ships into the Arctic and lost everyone. Shackleton lost his ship in the Weddell Sea and brought home twenty-eight men out of twenty-eight. The Endurance is the only major polar expedition of the Heroic Age in which leadership did the one thing the British Empire considered optional: it kept its men alive. The wreck the world spent a century looking for was the wreck of a successful catastrophe.
Shackleton's Imperial Trans-Antarctic Expedition and the Last Great Polar Prize
The South Pole Was Already Lost: Shackleton's New Goal
The South Pole had been claimed in December 1911 by Roald Amundsen and his Norwegian dog teams. Robert Falcon Scott, attempting the same feat for the British Empire, had reached the pole thirty-four days later and died on the way back. By the time the news of Scott's death reached London in early 1913, the polar prize most coveted by the imperial powers was no longer available. Someone else had it, and someone else's men had died trying.
Shackleton needed a new objective. He had been south twice already — once with Scott on the Discovery expedition of 1901, and once as leader of his own Nimrod expedition in 1908, on which he had reached 88°23'S, ninety-seven miles from the pole, and turned back rather than die. He understood Antarctica in a way few Edwardians did: as a continent, not a flag. The new prize, the only one left worth funding, was the continent itself. A crossing. Eighteen hundred miles from the Weddell Sea coast over the South Pole and down to the Ross Sea, the longest sledging journey ever attempted.
The plan required two ships. The Endurance would carry Shackleton's main party to the Weddell Sea, where they would land and march. The Aurora would land a support party on the Ross Sea side at Cape Evans — Scott's old base — and lay supply depots inland that Shackleton's group would consume on the second half of the crossing. Shackleton named the project the Imperial Trans-Antarctic Expedition and raised the funding from Scottish industrialist Sir James Caird, the British government, and a string of private donors who wanted their names attached to a national effort. The expedition sailed from Plymouth on 8 August 1914, four days after Britain declared war on Germany.
Recruiting the Crew of the Endurance in 1914
Shackleton chose his men personally and quickly, often in interviews lasting under five minutes. He was looking for temperament more than experience. The naval officers he wanted were the ones who could spend two years in a small wooden building without needing to kill anyone. He hired Frank Wild as second-in-command — Wild had been with him on the Nimrod and was the most reliable man Shackleton had ever met. Frank Worsley, a New Zealand merchant captain, was hired to navigate the Endurance, a decision that would prove, in retrospect, one of the most consequential personnel choices in the history of exploration. Tom Crean, an Irish chief petty officer who had nearly died with Scott on the Terra Nova expedition, signed on as second officer. Frank Hurley, an Australian photographer with a reputation for getting impossible images at any cost, took the camera position. The ship's surgeon was Alexander Macklin. The cook was Charles Green. The doctor-biologist was James McIlroy. The carpenter, Henry McNish — a sour-tempered Scotsman known to everyone as "Chippy" — would later perform the work that saved the entire expedition.
A widely repeated story claims Shackleton placed an advertisement in a London newspaper reading "Men wanted for hazardous journey. Low wages, bitter cold, long hours of complete darkness. Safe return doubtful. Honour and recognition in event of success." No copy of the advertisement has ever been found in any London paper of 1914, and the line is almost certainly apocryphal. What is true is that Shackleton received over five thousand applications for twenty-eight positions. The men who got the jobs were chosen, in part, on the basis of singing voice. He wanted men who could keep morale up in the dark.
Caught in the Pack Ice of the Weddell Sea
The Endurance Enters the Ice in December 1914
The Endurance was a 144-foot, three-masted barquentine built at the Framnæs shipyard in Sandefjord, Norway, in 1912. She had been constructed as a tourist vessel for Arctic cruises but had never sailed in that role. Her hull was reinforced with greenheart, the hardest tropical hardwood known, sheathed over a six-foot-thick layer of laminated planks designed to ride up over pack ice rather than be crushed by it. Shackleton bought her cheap because the original buyer had gone bankrupt. The hull was the strongest ever built for ice work outside the Russian icebreaker fleet.
She sailed from South Georgia on 5 December 1914, heading south into the Weddell Sea — the most ice-choked body of water on the planet, a closed gulf where the prevailing currents drag pack ice in a slow clockwise gyre against the continent and never let it go. By 19 January 1915, after only six weeks of southerly progress, the Endurance was beset. The ice closed in from every direction at once. The ship stopped moving. Within days she was frozen fast, locked into a floe roughly a mile across, and the floe itself was drifting with the current at the rate of one or two miles a day, in directions over which neither Shackleton nor Worsley had any control.
The expedition was supposed to land men ashore. They had not landed. They were now frozen in motion, eighty miles from a coast they could see on clear days but could not reach. Shackleton's options narrowed by the week. By February 1915 the option had become singular: wait for spring, hope the ice broke up, and try again the following season.
Frozen In: 281 Days on a Drifting Ship
The men set up routines. They hunted seal and penguin to feed themselves and the dogs. They played football on the floe. They built kennels out of ice for the sixty-nine sledge dogs and called the layout "Dogloo Town." Hurley took photographs that have since become the visual signature of the entire Heroic Age: the Endurance listing slightly in the floe with her masts hung in rime, men in heavy wool standing in attitudes of forced normalcy, the surreal black silhouettes of sledge dogs against an absolutely white horizon. The ship's piano was used. The expedition's small library circulated. A manuscript newspaper, the Endurance Magazine, was kept up. The men celebrated the King's birthday, Christmas, and the midwinter sun. Through it all, the ice pressed in.
Pressure ridges began rising around the hull in July. The men could hear the floe groaning at night, a sound Shackleton described as the sound of a thousand pianos being played at once with the wrong fingers. By August the ice had begun lifting the Endurance bodily, tilting her hull thirty degrees to port. By October the timbers were audibly cracking. The ship's interior fittings were popping out of their joints from the pressure. The men kept working through it because there was nothing else to do.
On 24 October 1915 the pack made its decisive move. A pressure wave from the south compressed the floe against the hull from three sides at once. The starboard side of the Endurance split open along the keel. Water flooded into the engine room. Shackleton ordered the dogs and the lifeboats off the ship and the men onto the floe. They watched from a distance over the next three weeks as the ship died slowly. The masts came down one by one. The hull twisted and reopened along new fault lines.
The Ship Crushed: October 27, 1915
The men camped on the ice two hundred yards from the wreck. They called it Ocean Camp. The ice beneath them was variable in thickness and quality; some days they woke to find a crack had opened under one of the tents during the night. They salvaged what they could from the dying ship. Hurley dove repeatedly into the flooded hold to retrieve his glass plate negatives, eventually surfacing with about 150 of the 400 he had taken. He destroyed the rest by smashing them on the ice in front of Shackleton, who insisted that any plates left behind be broken so Hurley would not be tempted to go back for them. Henry McNish, the carpenter, salvaged tools, planks, and the ship's longboat fittings.
The Endurance finally sank on 21 November 1915. Shackleton wrote in his diary that night: "I cannot write about it." He did not need to. The men had now been on the ice with no ship for a month and would be on it for another five.
Patience Camp and the Drift North
Living on a Floating Ice Floe for Five Months
Shackleton renamed the camp Patience Camp in late December 1915. The name was a directive. The floe they were camped on was being carried slowly north by the Weddell Gyre, which gave them, in theory, a chance of drifting close enough to land or to open water for the boats to be launched. In practice it meant five months of psychological warfare against a flat white emptiness. The men rationed seal meat. They ran out of milk and sugar. They killed the dogs in stages, beginning with the puppies, because there was no longer enough food for them and they could not be allowed to eat the men's rations. Shackleton himself shot his favorite dog, a husky named Songster. Macklin wrote in his journal: "I have known many men I would readily have shot in preference."
The floe shrank under them. By February 1916 they had moved their tents three times to stay ahead of cracks. By March the surface had thinned enough that walking on it required care. By early April the floe was small enough that the men could no longer pretend they were on something solid. On the morning of 9 April 1916, the ice they were camped on cracked directly under the cook tent. Shackleton gave the order. The three lifeboats — the James Caird, the Stancomb Wills, and the Dudley Docker — were dragged to the edge of the floe. Twenty-eight men climbed in. The boats pushed off into a freezing sea full of ice fragments and a swell that the men, who had been on a stationary surface for sixteen months, had forgotten how to balance against.
April 9, 1916: The Lifeboats Launch
Seven days at sea in open boats. The men slept in shifts in puddles of freezing seawater. They had no compass that worked reliably in the high southern latitudes and no chart accurate enough to trust. Worsley took sextant readings whenever the sun briefly appeared between cloud banks, often standing in the bow of the Dudley Docker with two men holding his legs while he caught a horizon between waves. Their fingers froze to the boat's gunwales. Their lips split. The temperature inside the boats was below freezing day and night. One man, the steward Thomas Orde-Lees, developed frostbite so severe he could no longer feed himself. They had no fuel for cooking. They drank seawater when their freshwater ran out, which made them sicker.
On 15 April 1916, after five days of the worst sailing conditions any of them had ever experienced, the boats made landfall at Elephant Island, a black volcanic crag on the South Shetland chain. It was the first piece of solid ground any of them had stood on in 497 days. Several men collapsed weeping on the beach. Several others laughed uncontrollably. One ate a handful of pebbles, apparently to confirm to himself that they were real.
Elephant Island and the Open-Boat Voyage to South Georgia
Stranded on Elephant Island
Elephant Island is uninhabited and uninhabitable. It is a steep glaciated rock with no harbor, no shelter, no permanent food source beyond seal and penguin colonies on a few exposed beaches. The men landed at a point Shackleton named Point Wild, after Frank Wild, who would be left in charge of the men who stayed there. The beach was 200 feet wide and rose almost vertically into a glacier. The wind blew constantly. The temperature stayed below freezing. The men flipped the two smaller lifeboats, the Stancomb Wills and the Dudley Docker, upside down on a low stone wall and lived under them for the next four months.
Twenty-two men under two upturned lifeboats. They cooked seal meat over blubber lamps. They burned the boats' planking and their own clothing for warmth. They developed frostbite, gangrene, and chronic dysentery. One man, Perce Blackborow — a Welsh teenage stowaway who had hidden in a locker when the Endurance sailed and been kept on by Shackleton out of bemused admiration — had the toes of his left foot amputated by Macklin and McIlroy on a kitchen table made from packing crates, with chloroform as the only anaesthetic. He survived.
Nobody on Earth knew they were on Elephant Island. The ship was lost. The expedition was overdue but assumed to be still operating. The British public was preoccupied with the Western Front, where the Battle of the Somme was being prepared. Shackleton calculated correctly that no rescue would come. If the men were going to be saved, he would have to bring the rescue himself.
Shackleton, Worsley, Crean and the James Caird: 800 Miles in an Open Boat
Shackleton, Worsley, and Crean — together with carpenter McNish, sailmaker Timothy McCarthy, and able seaman John Vincent — left Elephant Island on 24 April 1916 in the James Caird, a 22-foot lifeboat that McNish had reinforced over the previous week with planks salvaged from the Endurance's wreck and a deck cobbled together from canvas and packing-case wood. Their target was South Georgia, a Norwegian whaling outpost approximately 800 nautical miles to the northeast across what is widely considered the most violent stretch of ocean on Earth: the Drake Passage convergence, where the Atlantic and Pacific funnel into the Southern Ocean and produce waves regularly exceeding sixty feet.
Worsley navigated by sextant, taking readings approximately four times in the entire voyage because cloud cover prevented sun sights any more often than that. The math he did each night by candlelight in a soaking-wet logbook, balancing the book on his knees as the boat rolled, has been studied by professional navigators ever since. He was attempting to thread a 22-foot boat onto a 100-mile-long target across 800 miles of empty sea with four star sights. A standard error of one degree in his calculations would have put them in open water with no way to correct.
The voyage took fifteen days. The boat shipped water continuously and the men bailed in shifts. Vincent collapsed psychologically partway through and had to be relieved. McCarthy, the youngest of the boat crew, kept the others laughing and was later described by Worsley as the bravest man he had ever known. On the eleventh day a wave broke over them that Shackleton estimated as the largest he had ever seen at sea, and which capsized the boat partially before it righted. They survived because the deck McNish had built held.
On 8 May 1916 they sighted South Georgia. They could not land on the eastern coast where the whaling stations were because the wind was driving them onto the rocks. They were forced to come ashore at King Haakon Bay on the southwestern coast — the wrong side of the island. The whaling stations were on the other side. Between the James Caird and Stromness Whaling Station lay an unmapped, unclimbed range of glaciated mountains, 9,000 feet high, that no human being had ever crossed.
The Crossing of South Georgia
Shackleton, Worsley, and Crean left McNish, McCarthy, and Vincent with the boat on 19 May 1916 and walked into the mountains. They had no climbing equipment beyond a fifty-foot length of rope and a carpenter's adze that McNish had given them. They had screwed brass screws from the boat's hull into the soles of their boots for traction. They climbed for thirty-six hours without sleeping. At one point, faced with a slope they could not descend in the failing light, Shackleton ordered the three of them to coil the rope, sit on it as a sledge, link arms, and slide down into the dark, with no idea what was at the bottom. They survived. The bottom turned out to be a soft snowfield approximately 2,000 feet below.
They walked into Stromness Whaling Station on the morning of 20 May 1916. They had not bathed in seventeen months. Their clothes were rags. Their hair and beards were matted with seal grease and salt. The first people they encountered were two children, who saw them at the edge of the settlement and ran away screaming. The station manager, Thoralf Sørlle — who had hosted the Endurance eighteen months earlier — did not recognize Shackleton when the three men walked into his office. Shackleton said: "My name is Shackleton." Sørlle, according to multiple accounts, turned away and wept.
The Rescue and the Forgotten Half of the Expedition
Four Attempts to Rescue the Elephant Island Men
Shackleton organized the rescue of the twenty-two men still on Elephant Island within hours of arriving at Stromness. McNish, McCarthy, and Vincent were retrieved from King Haakon Bay first. Shackleton then attempted to reach Elephant Island three times in three different ships and was turned back each time by pack ice. He refused to delegate. He insisted on being on every rescue attempt personally. The fourth attempt, in the Chilean naval tug Yelcho in August 1916, finally broke through. Shackleton stood at the bow as the ship approached Point Wild and counted heads. "Are you all well?" he shouted across the water to Frank Wild on the beach. Wild's reply: "All safe, all well."
Twenty-two men had spent four and a half months on Elephant Island under two upturned boats and not a single one had died. The combined survival of all twenty-eight expedition members through twenty-two months of disasters that should have killed any of them, by any actuarial reckoning, several times over, is the achievement on which Shackleton's reputation rests. He was not a great explorer in the conventional sense. He never reached a major geographical objective. He was a great leader of men in conditions designed to kill them.
The Ross Sea Party: The Tragedy on the Other Side of the Continent
The story almost everyone tells stops here, at the Elephant Island rescue. It leaves out half the expedition.
On the other side of Antarctica, the Aurora had been laying supply depots on the Ross Sea side under the command of Aeneas Mackintosh. Their orders were to lay caches inland from Cape Evans for Shackleton's overland party — the party that, unknown to the depot-layers, was at that moment marooned on Elephant Island and would never use the depots at all. The Aurora had been carried out to sea in a storm in early 1915, leaving ten men stranded ashore at Cape Evans with the supplies and clothing left behind by Robert Falcon Scott three years earlier. They laid the depots they had been ordered to lay. Three of them died in the process: Mackintosh himself and Victor Hayward walked out onto unstable sea ice in a blizzard and were never seen again, and Arnold Spencer-Smith, a chaplain, died of scurvy as his companions dragged him on a sledge across the ice shelf.
The seven survivors were rescued in January 1917 by the repaired Aurora, which Shackleton himself sailed south to collect them. The hut they had wintered in — Scott's Hut, still standing today at Cape Evans, frozen with their clothing and tin cans layered over Scott's — is the surviving physical record of the expedition's quiet half. The Imperial Trans-Antarctic Expedition is remembered as a triumph of survival because of what happened on the Weddell Sea side. On the Ross Sea side it killed three men laying depots for a continental crossing that never happened.
The 107-Year Search for the Wreck
The Last Known Position: Worsley's Coordinates
Frank Worsley took the last sextant reading of the Endurance on the day she sank. He recorded it in pencil in the ship's logbook, which he carried with him through the floe, the lifeboats, Elephant Island, and the open-boat voyage to South Georgia, and which he eventually delivered to the Royal Geographical Society in London. The reading: 68°39'30"S, 52°26'30"W. A single point in the central Weddell Sea, approximately 100 miles southeast of the original besetment site. For 107 years it was the only data anyone had about where the ship lay.
The Weddell Sea coordinates were nearly useless in practical terms. The wreck was sitting somewhere on a seabed roughly 3,000 meters down, in a body of water covered year-round by drifting pack ice that no surface vessel could reliably penetrate. Anyone who wanted to find the Endurance would need to first get a ship to within a few miles of Worsley's point — itself a major operation requiring an icebreaker — and then deploy underwater equipment capable of operating at extreme depth, in extreme cold, and in conditions where the surface ship overhead could be carried away from the survey grid by drifting ice at any moment.
The Failed Searches
The first serious attempt was led by David Mearns, a marine archaeologist, in 2001, but never reached the search area because the expedition's icebreaker was unable to penetrate the pack. A second expedition, in 2019 — the Weddell Sea Expedition, organized by the Flotilla Foundation and led by polar geographer Julian Dowdeswell — did reach the area aboard the South African icebreaker S.A. Agulhas II. It deployed an autonomous underwater vehicle (AUV) to survey Worsley's coordinates. The AUV was lost. No wreck was found. The expedition retreated.
Each failure clarified what the next attempt would need: a more capable AUV, redundant systems, and a survey window long enough to absorb mechanical failures and weather delays. By 2021 the technological gap had narrowed enough that one more attempt was considered viable.
The Endurance22 Expedition: March 5, 2022
The Falklands Maritime Heritage Trust funded the Endurance22 expedition in 2022. The team was led by veteran marine archaeologist Mensun Bound and operated again from the S.A. Agulhas II. They deployed two Saab Sabertooth hybrid AUVs, capable of both autonomous survey and tethered remote operation, and equipped with high-resolution side-scan sonar and 4K cameras. The expedition entered the search area in mid-February 2022. The ice that year was the heaviest on record. The window was small.
On the afternoon of 5 March 2022, after two weeks of surveys producing nothing, the side-scan sonar of one of the AUVs returned an image. A three-masted vessel, sitting upright on the seabed, 3,008 meters down. Four nautical miles from Worsley's century-old coordinates. The team that examined the image first did not allow themselves to believe it. The high-resolution camera was sent down on the next dive. The footage came back showing a ship in a state of preservation that nobody on the expedition had thought possible.
The hull was largely intact. The masts had broken but lay on the seabed beside the ship. The ship's wheel was still in place at the helm. Ceramic plates were stacked on shelves in what had been the wardroom. Crew boots stood upright on the deck. A single flare gun lay on the rail. The taffrail at the stern was unbroken, and across it, in raised gold letters that the camera lights caught with hallucinatory clarity, was the word ENDURANCE.
The Antarctic deep had preserved her almost completely. The Weddell Sea is below 0°C year-round at depth, and the absence of wood-boring organisms — particularly Teredo navalis, the shipworm that destroys most wooden wrecks within a decade — meant that the timbers had not been eaten. The ship was the second time capsule the expedition produced. The hut at Cape Evans on one side of the continent. The wreck on the other. Both held by cold.
Visiting the Endurance and the Ethics of a Protected Wreck
The wreck of the Endurance cannot be visited. It cannot be salvaged. It cannot be touched. Within hours of its discovery, the Falklands Maritime Heritage Trust applied for and received protection of the site as Historic Site and Monument No. 93 under the Antarctic Treaty's Antarctic Treaty Consultative Meeting (ATCM), the highest level of legal protection available for any underwater cultural heritage on the continent. No diving, no recovery, no removal of objects, and no contact with the wreck of any kind is permitted. The Sabertooth AUVs that filmed her were specifically programmed to maintain a minimum standoff distance from the hull. Only photography and 4K video footage was taken back. Everything else stays where it is.
The Weddell Sea itself remains one of the least accessible bodies of water on the planet. A small number of specialist Antarctic cruises operated by IAATO members enter the northwestern Weddell Sea each austral summer, but reaching the central Weddell Sea where the wreck lies requires icebreaker support and is not commercially feasible. Visitors to Antarctica can stand on Elephant Island, where Frank Wild's twenty-two men survived under the upturned boats. They can visit the Scott's Hut at Cape Evans, where the Ross Sea Party of the same expedition wintered for two years and lost three men. They cannot visit the wreck itself. The closest a member of the public will ever get to the Endurance is the photograph and video archive released by the Endurance22 expedition.
The wreck is not a tomb. Nobody died on the Endurance. The ship is the physical record of the only major polar disaster in which leadership chose to bring its men home over reaching its objective. She lies on the seabed of the Weddell Sea, three kilometers down, name still legible, looking from the side-scan images almost as she did the day Frank Hurley took his final photographs of her sinking. She is the most successful failed ship in the history of exploration. The continent that took her has held her, exactly as she was, for a hundred and ten years. There is no reason to believe she will not still be there in another thousand.
Frequently Asked Questions
Where is the wreck of the Endurance located?
The wreck lies in the central Weddell Sea, off the Antarctic coast, at coordinates approximately 68°44'21"S, 52°19'47"W. It sits on the seabed at a depth of 3,008 meters — roughly three kilometers below the surface. The wreck is approximately four nautical miles south of the position recorded by Captain Frank Worsley in the ship's logbook on the day she sank in 1915. The Weddell Sea is one of the most ice-choked and inaccessible bodies of water on Earth, and the wreck site is covered year-round by drifting pack ice.
When did the Endurance sink and how?
The Endurance was crushed by Weddell Sea pack ice and sank on 21 November 1915. The ship had been frozen into the ice since 19 January 1915 and had drifted with the floe for ten months. Pressure from the surrounding pack progressively compressed and twisted the hull through October 1915 until the timbers split open along the keel on 24 October. The men evacuated to the ice and watched the ship die slowly over the next four weeks. She finally went under on 21 November. Every one of the 28 men aboard survived the sinking.
How were Shackleton's men rescued?
After the ship sank, the men camped on the ice for five months as the floe drifted north. When the ice broke up in April 1916, they sailed three lifeboats to Elephant Island, an uninhabited rock in the South Shetland chain. Twenty-two men remained on the island under two upturned lifeboats while Shackleton, Worsley, and four others sailed an open 22-foot boat called the James Caird approximately 800 miles to South Georgia. The three of them then climbed across the unmapped, glaciated mountains of the island in 36 hours to reach the Stromness whaling station. Shackleton organized four rescue attempts and finally retrieved all 22 men from Elephant Island in August 1916 aboard the Chilean tug Yelcho.
When was the Endurance wreck found?
The wreck was located on 5 March 2022 by the Endurance22 expedition, organized by the Falklands Maritime Heritage Trust and led by marine archaeologist Mensun Bound. The expedition operated from the South African icebreaker S.A. Agulhas II and used Saab Sabertooth autonomous underwater vehicles to survey the seabed in the central Weddell Sea. The wreck was found four nautical miles from the position Captain Frank Worsley recorded by sextant in 1915. It was the first time anyone had located the ship in the 107 years since it sank.
Why is the wreck so well preserved after more than a century?
The Weddell Sea is below 0°C year-round at depth, and the dark cold-water environment is largely free of Teredo navalis (the shipworm) and other wood-boring organisms that destroy most wooden wrecks within a decade or two. The ship sank in calm conditions onto a soft seabed and has not been subjected to currents strong enough to disturb it. Footage from the Sabertooth AUVs shows that the hull is largely intact, the masts are lying beside the ship, the helm wheel remains in place, the ship's name is still legible on the stern, and small artifacts including ceramic plates and crew boots remain in their original positions on deck.
Can anyone visit the Endurance wreck?
No. The wreck is protected as Historic Site and Monument No. 93 under the Antarctic Treaty. No diving, no salvage, no recovery of artifacts, and no physical contact with the wreck is permitted. The Endurance22 expedition's AUVs were programmed to maintain a minimum distance from the hull and only recorded photographic and video documentation. The wreck site itself, in the central Weddell Sea at 3,008 meters depth and under year-round pack ice, is in any case beyond the reach of normal Antarctic tourism. The closest a visitor can come to the expedition today is Elephant Island, occasionally accessible via specialist Antarctic cruises, or the Scott's Hut at Cape Evans on the opposite side of the continent.
Did anyone die on the Imperial Trans-Antarctic Expedition?
Three men died, but not on the Endurance. All 28 men aboard the Endurance survived the loss of the ship and the entire 22-month ordeal that followed. The deaths occurred on the other side of Antarctica, among the Ross Sea Party of the same expedition, which had been laying supply depots from Cape Evans for the overland crossing that never happened. Aeneas Mackintosh and Victor Hayward walked onto unstable sea ice in a blizzard and were never seen again. Arnold Spencer-Smith, a chaplain, died of scurvy on the ice shelf as his companions dragged him on a sledge. The seven Ross Sea Party survivors were rescued in January 1917.
