Dogs Join the Search for Amelia Earhart’s Remains

The quest to find Amelia Earhart’s final resting place just got a little more interesting, as four National Geographic-sponsored bone-sniffing border collies set sail for a remote Pacific island.

The famed aviatrix and her navigator were last seen on July 2, 1937, soaring into the sky above New Guinea. We know where they were headed—Howland Island, a mere speck in the ocean—but we don’t know where they went. There are plenty of theories, of course. Some people think Earhart was actually a spy who went into hiding after completing her final mission. Others think she was captured.

But some of the most compelling evidence comes from Nikumaroro, an uninhabited atoll located about 1000 miles north of Fiji. The island is just 350 nautical miles southwest of Howland Island. At low tide, its exposed reef could have made a welcoming spot to land an ailing plane. Most importantly, we’ve found bones there before; the British government recovered 13 human bones there in 1940.

Those bones have since been lost, as has the precise location of where they were discovered, but archaeologists believe they know where to find more.

So the International Group for Historic Aircraft Recovery (TIGHAR) is sending a new mission to the island, bolstered with some very special experts. Berkeley, Piper, Marcy, and Kayle all trained as remains detection dogs by the Institute for Canine Forensics.

“No other technology is more sophisticated than the dogs,” expert Fred Hiebert told National Geographic News. “They have a higher rate of success identifying things than ground-penetrating radar.” Hiebert is archaeologist in residence at the National Geographic Society, which sponsored the collies’ involvement.

The dogs’ job is to follow the scent of human bones, then alert their human counterparts, who will excavate in a wide circle around the targeted area. It probably won’t be an easy job. Heat, vegetation, and scavengers can all throw off the scent, and Nikumaroro is sweltering, dense with greenery, and crawling with bone-cracking coconut crabs.

That last thing might not be terrible. “The crabs are our friends,” Hiebert says. It’s possible that they found the remains themselves, then dragged them back to their burrows. The dark, underground holes could actually help preserve the remains and their scent.

Hiebert and his colleagues at TIGHAR know it’s a long shot. The scent trail likely went cold ages ago, if the bones are even still there, if they ever were there at all.

“But if the dogs are successful,” Hiebert says, “it will be the discovery of a lifetime.”

'Ship Graveyard' Discovered in the Black Sea Provides New Insights into Maritime History

In 2015, to learn how prehistoric humans dealt with the coastal impact of climate change, an international team of researchers in Bulgaria embarked on a multiyear geophysical survey of the Black Sea. Little did they know that the undertaking would morph into what's been dubbed "one of the largest maritime archaeological projects ever staged": As IFLScience reports, the team ended up discovering dozen of shipwrecks, dating from the 19th century all the way back to the 5th century BCE.

News of the "ship graveyard," as researchers have taken to calling it, was first announced in 2016. Following three field seasons, marine scientists have just returned from their final trip with recovered artifacts and new insights about ancient ship design and trade patterns.

Scientists from the Black Sea Maritime Project (Black Sea MAP), conducted by the University of Southampton's Center for Maritime Archaeology, used a host of high-tech equipment to survey the Black Sea's floor and take pictures. In all, they located around 60 ships spanning 2500 years of history.

The vessels were in remarkable condition, considering their age. The Black Sea is uniquely suited for preserving organic materials, as it contains two separate layers of water: a top layer that contains oxygen and salt, and a second salty layer with little oxygen or light. Organisms that eat organic matter can't survive in this environment, which is why the site's ships stayed relatively intact.

According to National Geographic, researchers were still able to make out the chisel and tool marks on planks, along with carved decorations. They also saw rigging materials, rope coils, tills, rudders, standing masts, and cargo.

Ships were discovered from the Classical, Roman, Byzantine, and Ottoman periods, with the oldest dating back to the 4th or 5th century BCE. One particularly exciting find was an ornately carved Ottoman ship, which researchers nicknamed Flower of the Black Sea due to its floral deck carvings. Meanwhile, a potentially Venetian ship from the 13th or 14th century provided scientists with a first-ever glimpse of the ships that were the precursors to those used during the Age of Exploration.

"That's never been seen archaeologically," expedition member Rodrigo Pacheco-Ruiz told The New York Times in 2016. "We couldn't believe our eyes."

To reconstruct how these vessels once looked, researchers used 3D software to combine thousands of still photos shot from different angles. This photogrammetric method allowed them to create digital models of the vessels and identify historical features that were once a mystery to archaeologists.

"There's one medieval trading vessel where the towers on the bow and stern are pretty much still there," said Ed Parker, CEO of Black Sea MAP, according to IFLScience. "It's as if you are looking at a ship in a movie, with ropes still on the deck and carvings in the wood."

Scientists say the ship graveyard will help them learn more about ancient trade routes, and how various Black Sea coastal communities were connected. That said, they're still committed to their initial goal of investigating ancient changes in the region's environment, using sedimentary core samples and other methods to learn more about the impact of sea level change after the last glacial cycle.

"Our primary aims are focused on the later prehistory of the region and in particular on human response to major environmental change," said Jon Adams, the project's chief investigator and a founding director of the University of Southampton's Centre for Maritime Archaeology, in a news statement. "We believe we now have an unparalleled archive of data with which to address these big questions about the human past."

Found: A Sunken German World War I-Era Submarine

During World War I, one of Germany's most formidable weapons was the U-boat, an advanced military submarine with torpedoes that sank countless Allied merchant and cargo ships. But while deadly, these submersibles weren't invincible, as evidenced by the recent discovery of a sunken German U-boat in the North Sea.

As ABC News reports, researchers located the UB II-type dive boat—a smaller submarine that typically plagued coastal waters—off the coast of Belgium, around 82 to 98 feet below the North Sea. The 88-foot vessel appears to have struck a mine with its upper deck, judging by damage suffered to its front.

The submarine is remarkably intact. Two of its torpedo tubes were destroyed, but one of them is still in good condition. The ship itself remained sealed, and may serve as a watery grave for up to 23 crew members.

The U-boat's final resting place hasn't been announced, as to prevent looting or damage, according to the BBC. Meanwhile, Belgian officials have contacted the German ambassador to see how they should proceed with any potential remains.

This isn't the first time a World War I-era U-boat has been found in Belgian waters. Experts have catalogued 11 such discoveries so far, but this one is reported to be the best preserved. The Chicago Tribune reports that since 18 U-boats were stationed in Bruges between 1915 and 1918, and 13 of them were destroyed, there might be even more of these kinds of finds to come.
