The Deepest Shipwreck Ever Found

by Aliya Whiteley

The oceans still hold many secrets. We're only just beginning to find ways to explore the deepest trenches, using technological advances to look at the strange creatures and landscapes that inhabit the total darkness found thousands of feet below the surface.

But though they've been difficult to access, there are also human artifacts at those depths—objects that have sunk to lie, undisturbed, for many years. Humans have been making boats since prehistoric times; who knows how many wrecks now lie in the deep?

The question of just how many wrecks lie in the deep is difficult to answer, but according to Guinness World Records, the deepest shipwreck that has been identified so far is a German blockade runner from World War II—the SS Rio Grande. In early January 1944, it was sunk by two U.S. ships in the South Atlantic Ocean. It lies at a depth of about 18,900 feet—more than 3.5 miles below the surface—and was discovered on November 28, 1996, using side-scanning sonar technology. Two days later, the company responsible for the find, Blue Water Recoveries, confirmed the wreck using a remotely operated vehicle.

It’s impossible to even guess at how many shipwrecks might yet lie in the deepest parts of the oceans (the Mariana Trench reaches a depth of about 36,000 feet). Just to give some perspective, more than 150 ships sank in January 1944 alone.

Not all sunken ships are wartime casualties, of course. One of the oldest shipwrecks found thus far was a cargo ship that was discovered off the coast of southern Turkey in 1982. The Uluburun wreck is 3300 years old. The cargo it carried has been recovered by divers, and included copper, tin, glass, ebony, weapons, food, elephant tusks, hippopotamus teeth, tortoise shell, and amber beads. Some personal items from the crew were also recovered, including a scarab made of gold that bears the seal of Nefertiti, wife of the pharaoh Akhenaten. It now resides in the Bodrum Museum of Underwater Archaeology. More recently, divers in Greece have found wrecks dating as far back as 525 BCE.

It’s staggering to imagine how many crafts, and how many people, must have been claimed by the sea over the centuries—that technology is now, finally, allowing us to find.

History
Researchers Find 100-Year-Old Antarctic Fruitcake in 'Excellent Condition'

If you want a snack that really won’t go bad, consider the fruitcake. Conservationists working with artifacts from Cape Adare, Antarctica, just discovered a remarkably well-preserved fruitcake dating back a full century, according to Gizmodo.

The fruitcake dates back to Robert Falcon Scott’s disaster-plagued Terra Nova expedition, which began in 1910. Documentation proves that Scott brought tins of the same Huntley & Palmers fruitcake with him to Cape Adare, about 1700 miles south of New Zealand.

The 106-year-old fruitcake tin is rusted and its paper wrapper damaged—though still largely intact—but the cake itself “was in excellent condition,” as a press release from the New Zealand-based Antarctic Heritage Trust, whose researchers discovered the tin, describes. The release says it “looked and smelt (almost) edible,” which is a glowing review for a food that dates back to William Taft’s presidency.

Why fruitcake? “It’s an ideal high-energy food for Antarctic conditions, and is still a favorite item on modern trips to the Ice,” according to the AHT’s project manager for artifacts, Lizzie Meek. Four AHT conservators have been working to preserve almost 1500 artifacts from Cape Adare, where Norwegian explorer Carsten Borchgrevink erected the first buildings in Antarctica. (Scott’s expedition later used the same huts.) They're still standing, and the AHT’s next project will be preserving the structures.

The Cape Adare site is an Antarctic Specially Protected Area, and the trust is working under a permit that requires its conservators to return any artifacts to the huts after they’ve been restored, meaning Scott’s fruitcake will eventually go back to where it was found.

Surprisingly, this is not the first fruitcake that has stayed edible for more than a century. Fidelia Ford made a holiday fruitcake in 1878, and it’s still in the family. It’s not quite fresh, though. One of Ford’s descendants reviewed it thusly: “Not much of a taste, no, and not good.” Given that Scott’s fruitcake is set to return to Cape Adare eventually, it’s doubtful that anyone will get a taste. We’ll just have to use our imaginations.

Scientists Devise Clever Way to Test Old Manuscripts’ DNA

When encountering an obstacle, some people stop and give up, some force their way through, and others find another way around. That's what scientists in the United Kingdom have done with a delicate manuscript from the Dark Ages. Barred from taking parchment samples, the resourceful researchers instead analyzed the eraser crumbs left behind after archivists cleaned the paper. They describe their findings in an article on the prepress server bioRxiv.

Co-author and archaeologist Matthew Collins of the University of York did not start out a manuscript man. Collins had been trying to extract DNA from animal bones unearthed at a Viking settlement to learn more about the culture's use of livestock. But the bones had decayed too far to offer much in the way of genetic material. "You can imagine the frustration," Collins said in an interview with The Atlantic.

Then he realized that animal remains can be more than just bones. There are skins, too—and those, at least, we've taken some pains to preserve. At least the ones we've written on.

"You look at [archive] shelves," Collins said, "and every one of them has a skin of an animal with a date written on it."

Collins's excitement at discovering this untapped bounty of data was soon tempered when he and his collaborator, biochemist Sarah Fiddyment, learned that sampling the manuscripts was completely off-limits.

But they weren't about to give up that easily. Fiddyment spent weeks following the conservators as they worked with the fragile animal-skin paper, learning their process and watching for possible openings. Finally, she saw it: eraser crumbs.

Conservators routinely use PVC erasers to lift stains, grime, and damage from historic documents. The friction created by gently rubbing the eraser against the paper creates an electric charge that pulls in molecules of dirt and oil. And probably other things, too, Fiddyment thought.

Fiddyment, Collins, and their colleagues began collecting eraser crumbs from manuscript conservators around the world. They analyzed each document's chemical makeup and were even able to compare proteins to identify the livestock species responsible for the skin.

The next step was to look at the DNA itself. The researchers turned to the York Gospels, a leatherbound Bible with pages dating back to the year 990. By collecting another tiny pile of eraser crumbs from cleanup of eight pages, they were able to collect enough of a sample to run thorough DNA tests.

Those pages had quite a lot to say about their creation and history. The tests revealed 1000-year-old genetic material from the cows and sheep that gave the book its parchment pages. Remarkably, the DNA was so intact that the scientists could identify the cows' ancestry (something close to our modern-day Norwegian reds and Holsteins) and sex (mostly female).

The pages also contained human DNA and even bacteria, most likely from the hands and saliva of the people who made, wrote, and used the book.

Speaking to The Atlantic, parchment expert Bruce Holsinger of the University of Virginia called the findings "an exciting breakthrough."
