Submarine Expedition Reveals Parts of the Titanic Have Fully Decayed

In 1985, oceanographers Robert Ballard, Jean-Louis Michel, and their crew located the wreck of the RMS Titanic at the bottom of the Atlantic Ocean. Images of the shipwreck have since become as iconic as photographs of the ocean liner taken before the 1912 tragedy. But the ruin's time in the ocean is limited. As part of an upcoming documentary, a crew of scientists carried out the first manned expedition to the wreck in 14 years and discovered the Titanic is rapidly decaying, BBC reports.

After it sank, the Titanic settled in two parts on the seafloor about 370 miles off the coast of Newfoundland, Canada. Most of the wreck is still intact, but a lot has changed since 2005, when it was last visited by a human-occupied submersible.

While working on a film for Atlantic Productions London, an exploration team from Triton Submarines visited the wreck five times over eight days and discovered that entire sections of the ship have disappeared. The starboard side of the officer's quarters has deteriorated, and the captain's bathtub is totally gone. The deck house on the same side and the sloping lounge roof of the bow are also on the brink of collapse, according to the crew.

Unlike other artifacts and historic sites, there's no way to preserve the wreckage of the Titanic for future generations. Churning ocean currents, corrosive salt, and metal-eating bacteria will continue to break down the steel behemoth until it becomes part of the sea. Some experts estimate that by 2030, it's likely that no part of the wreck will remain.

Whether that projection is off by years or decades, these findings suggest that every new team that visits the Titanic may find something different than the team before them. On this most recent expedition, the Triton Submarines exploration team was able to film the wreck in 4K for the first time. That footage may end up being some of the last ever captured of many elements of the ship.

Swedish Divers Just Discovered Two Shipwrecks That Might Be Related to the Famous Vasa Warship

In 1625, King Gustavus II Adolphus of Sweden commissioned shipbuilders to create the most beautiful, lethal flagship that ever existed, as a symbol of Sweden’s naval strength. Three years later, crowds gathered to watch the Vasa, named after Sweden’s royal house, set sail for the first time. But less than a mile into its maiden voyage, the poorly and hastily constructed warship sunk to the bottom of the Baltic Sea, where it remained until 1961 when it was salvaged and later transported to the Vasa Museum.

Now, the Guardian reports Swedish maritime archaeologists from Vrak—Museum of Wrecks have located two shipwrecks in the Swedish archipelago outside of Vaxholm that could be linked to the Vasa. This is because the shipwright responsible for the Vasa built three other ships, the Äpplet, the Kronan, and the Scepter (though, unlike their ill-fated sibling, they actually made it into battle).

“It was like swimming around the Vasa ship,” maritime archaeologist Jim Hansson said in a museum press release. They believe the first wreck they discovered may be the Äpplet, and the second wreck could be either the Kronan or the Scepter.

“We think that some of them were sunk in the area,” Patrik Hoglund, another Vrak archaeologist, told the Guardian. But these ships didn’t capsize because of shoddy engineering or even an enemy attack. Instead, experts believe the Swedish navy intentionally sunk them after they were decommissioned, so their wrecks would function as surprise spike strips to damage approaching enemy ships.

The divers brought back wood samples from the wrecks to send to a laboratory for testing. Once they know when and where the timber came from, they can cross-reference the data with Swedish archives to find out if it matches information from the Vasa.

Even if the warships do turn out to be the Vasa’s long-lost siblings, it’s unlikely that they’ll be salvaged and displayed alongside it, since the Baltic Sea’s brackish waters actually preserve them much better than a museum could.

Sweden isn’t the only nation that boasts a beautiful shipwreck or two—here are 10 other shipwrecks around the world that you can visit.

How the T. Rex at the American Museum of Natural History Became an Icon

When asked to think of a Tyrannosaurus rex, you may picture the dinosaur from the original King Kong (1933), the famous vintage illustration by Charles Knight, or perhaps the sinister fossil gracing the poster for Jurassic Park (1993). Each of these pop culture depictions of T. Rex was inspired by a single specimen: A skeleton on display at the American Museum of Natural History in New York City dubbed AMNH 5027.

In the video below, the AMNH explains how their fossil became the most iconic T. Rex—and therefore the most iconic dinosaur—in history. From 1915 to about 1940, it was the only the mounted T. Rex skeleton on display to the public. That means that most movies created in the early 20th century featuring a T. Rex—including The Ghost of Slumber Mountain (1918), King Kong, and Fantasia (1940)—were either directly or indirectly inspired by the museum's specimen. AMNH 5027 was incorrectly displayed standing upright with its tail on the ground for decades, which is why so many early depictions of the dinosaur in pop culture show it with the same posture.

The fossil's influence on the world isn't limited to early 20th century cinema. When brainstorming ideas for Jurassic Park's book cover, designer Chip Kidd went to the American Museum of Natural History for inspiration. He used AMNH 5027 as the model for one of the most iconic book jackets ever made. The design was repurposed in the posters for Jurassic Park the movie, and the rex's silhouette has since appeared on countless toys, T-shirts, and other merchandise.

The image has become synonymous with the species, but there's one small detail that's unique to AMNH 5027. The dinosaur in the Jurassic Park artwork has a small bump on the inside of its skull. This bump formed when a bone in the original specimen got pushed out of place during fossilization, and today it's a distinct feature that makes its profile instantly recognizable.

To learn more about the huge impact AMNH 5027 has had in the last century or so of its 65 million years on Earth, check out the video below.
