9 Amazing Statues You Can Only See Underwater

The vast oceans contain many natural wonders, but they are also home to some astounding additions made by humans. Across the world statues have been sunk into the oceans for a variety of reasons—as memorials, to offer protection to a fragile marine environment, or simply as art. Colored with algae and populated by coral, some of the statues have become tourist destinations in their own right.

1. CHRIST OF THE ABYSS // A MEMORIAL TO DIVERS LOST AT SEA

Famous Italian diver Duilio Marcante conceived the idea of placing a statue of Christ under the water near a popular dive site in San Fruttuoso, near Portofino, Italy, after his good friend and fellow diver Dario Gonzatti lost his life diving near that spot in 1947. Sculptor Guido Galletti received the commission, and created an 8-foot bronze statue of Christ with his arms outstretched. The statue was placed more than 50 feet underwater in 1954 and provides not just a memorial to those who have lost their lives at sea but also a reference point for divers in distress.

Christ of the Abyss has become a busy diving site and in 2003 the statue was removed from the ocean for refurbishment after it became corroded and lost a hand due to being hit with an anchor. It was returned to the sea in 2005. The beautiful and affecting statue has proved so popular it has been recast a number of times and copies now exist in St George, Grenada and Key Largo, Florida.

2. VIRGIN MARY // DETERRING ILLEGAL FISHING

In 2010 in Bohol, the Philippines, locals placed two statues 60 feet underwater near a very rare double barrier reef, the Danajon Bank. The delicate marine area had been a victim of overfishing and some fishermen were resorting to using dynamite and cyanide to increase their catch. In order to deter this destructive behavior, two 14-foot statues of the Virgin Mary and Baby Jesus were placed on the sea floor, apparently to remind everyone that God created this special marine environment. The initiative worked, and dynamite is no longer used for fear of damaging the religious icons. Instead, divers flock to the site to admire and pray at the statues.

3. OCEAN ATLAS // HOLDING THE OCEAN ALOFT

The largest known underwater statue is Ocean Atlas, made by sculptor Jason deCaires Taylor and placed 16 feet underwater off Nassau, the Bahamas, in 2014. The statue was designed to draw attention to the need to conserve the oceans. Ocean Atlas weighs 60 tons and depicts a girl sitting hunched over, seemingly holding up the ocean above her; the piece is inspired by the Greek legend of Atlas, the Titan who held the world aloft. DeCaires Taylor specializes in creating underwater works of art and uses special pH-neutral marine cement, which is intended to last for hundreds of years and encourages coral and seaweed to colonize it, forming an artificial reef.

4. MOLINERE, GRENADA // WORLD’S FIRST UNDERWATER SCULPTURE PARK

The world’s first underwater sculpture park was created in 2006 in Molinere Bay just off St. George's in Grenada, after the area was damaged by a storm surge. It was hoped that the sympathetic sculptures, also created by Jason deCaires Taylor, would help the sea life regenerate by providing surfaces for algae and coral to cling to. One of the first installations was Vicissitudes, a circle of life-sized figures with interlinked hands, cast from the bodies of local children. More recently, 14 new sculptures based on Amerindian art by local artist Troy Lewis have been added to the park, including a 3-foot high Zemi, or stone idol.

5. EASTER ISLAND STATUE // MYSTERIOUS MOAI

Off the coast of Easter Island, home to the amazing carved stone Moai figures, lies an underwater statue that is not all that it seems. The 10-foot tall concrete Moai is not an original ancient statue but a modern replica. Mystery surrounds the origins of the piece—some claim it was created by modern-day residents of Easter Island and placed underwater as a tourist attraction, while others assert that it was a prop created either for a Chilean television show or for a 1994 Kevin Costner movie. Whatever the truth, the statue has become a popular dive site, especially since the lack of pollution means that the crystal clear waters give divers a great view of the submerged statue.

6. AMPHITRITE // MERMAID STATUE OFF GRAND CAYMAN

In 2000, the Canadian artist Simon Morris created a 9-foot-tall bronze statue of a mermaid, named for Amphitrite, the wife of Greek god of the sea Poseidon. The 600-pound mermaid statue was sunk under 50 feet of water off the coast of Grand Cayman Island in Sunset Reef (an earlier version also exists in British Columbia). When the statue was put in place, it was lowered into the water using a crane before being towed to its resting place. To ensure the statue did not crack on its journey into the deep, three small holes were drilled into the head of the statue to allow air bubbles to escape. The statue is now a popular place for divers.

7. NEPTUNE MEMORIAL REEF // UNDERWATER MAUSOLEUM

The Neptune Memorial Reef off Key Biscayne, Florida, was created in 2007 as an underwater mausoleum with statues and memorials constructed from cremated remains. Built in the style of the lost city of Atlantis, the Neptune Memorial Reef is now the world’s largest human-made reef. Those wishing to have their loved one buried in this unique manner can have cremated remains mixed with non-porous cement, which is then fashioned into a statue or memorial stone of their choosing. Mourners (and curious divers alike) can then dive or snorkel the site to explore the vast underwater cemetery and coral garden and pay their respects.

8. RUINS OF BAIAE, ITALY // ROMAN ARCHAEOLOGICAL DIVE SITE

In Roman times, Baiae on the Bay of Naples was the equivalent of Las Vegas—a party site packed with lavish villas and populated by the elite. Unfortunately, the bay-side location proved its undoing, since the whole area is plagued by volcanic activity, and the entire city was abandoned by 1500 before being reclaimed by the sea. Today Baiae is a protected archaeological underwater park. Many of the statues have been removed to local museums, but excellent replicas stand in their place, ensuring the ruined temples retain their original character. Tourists can explore the area by glass-bottomed boat, snorkel, or scuba-diving, providing a tantalizing glimpse of this once thriving (and decadent) Roman resort.

9. MUSA // UNDERWATER SCULPTURE PARK

The Museo Subacuatico de Arte (MUSA) off Cancun, Mexico, is an underwater sculpture park for divers and snorkelers that now contains over 500 statues. Created in 2009, the site covers some 4520 square feet of otherwise featureless seabed and utilizes materials that promote sea life, creating an artificial reef. Six artists have created works for the underwater museum, ranging from interactive stone hoops through which divers can swim to Silent Evolution, the largest exhibit, which features a crowd of 450 life-sized statues. One of the aims of the project is to help protect the nearby natural reefs (which are becoming damaged through overuse) by diverting visitors to MUSA, an otherwise barren area of seabed.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

8 Common Dog Behaviors, Decoded
May 25, 2017

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
