Top 10 Mysterious Things Found Underwater

Hey YouTube, Jim here! Welcome to Top10 Archive! The Earth’s oceans are vast and mysterious,
and even top scientists still can’t be certain exactly what’s hidden down there. Thankfully, curious researchers are diving
deep below the surface of the earth to see what they can find. And every now and again they find things so
baffling and incredible that no explanation can be found. Here’s our list of the top ten mysterious
things found underwater. Before we take you on a journey beneath the

Over the years, many ancient cities have been discovered in the depths of the ocean, but
the Atlit Yam ruins are especially mysterious. Buried 8 to 12 meters, or 26 to 39 feet deep,
the 1984 discovery of the 9,000-year-old site is nothing short of fascinating. The city is thought to be from the Neolithic
era and is one of the oldest and largest civilizations ever discovered. Many interesting artifacts have been found
at the site in the Mediterranean Sea, including mysterious structures that date back thousands
of years. One such structure is an incredible ritual
site which consists of gigantic stones arranged in a circle around what was once a spring. A stone well was also found, which was first
used for water service, but due to a large number of remains found in it, it was later
thought to be used as a disposal pit. A total of 65 sets of human remains were located
around the city, and some of them have provided some of the earliest proof of tuberculosis. Bones belonging to wild and domestic animals
were also found, which seems to prove that the residents of Atlit Yam both raised and
hunted animals for food. 9. Manganese Balls
Back in 2015, a vast collection of metal balls were discovered in the Atlantic Ocean. Scientists looking for deep-sea creatures
between South America and Africa made the startling discovery of what looks to be thousands
of manganese balls scattered along the seabed. A German research ship was several hundred
miles off the coast of Barbados when the mesh net they were using to capture marine life
brought up several balls of manganese ore. Some were as big as softballs, and upon further
investigation, it was found that there were many, many others. Some were even as big as bowling balls, while
other just a few millimeters in circumference, and the mysterious thing is that nobody knows
where they came from. The metal lumps are formed from layers of
metal ore that have slowly crystallized to form the balls that were found. The center of the masses were either fossils,
rocks, or fragments of other nodules. 8. Underwater River
The idea of finding water underwater probably doesn’t sound that mysterious, but when
you consider the fact that this particular river is only accessible to experienced master
divers, it becomes a whole lot more impressive. The Cenote Angelita Cave is situated in the
Mayan Riviera in Mexico, and 90 feet below the water’s surface is a beautiful and fascinating
river that draws divers from all around the world. There are trees and plants adorning the river’s
banks, and it truly resembles a real-life river. It is, however, an illusion, and the river
is actually just a cloud of hydrogen sulfide created by mixing saltwater and freshwater
together. If you’re only interested in real underwater
rivers, the Black Sea’s offering might, erm, float your boat a little more. The river remains its own entity because the
water is much saltier than the water that surrounds it, and so, it’s denser. Its salinity also allows the river to run
faster than the surrounding Black Sea water, giving it a realistic appearance of a river. Oh, and if that wasn’t awesome enough, it’s
said that the river’s large volume would make it the world’s sixth largest river
if it was on land. 7. Zhemchug Canyon
From underwater rivers to an underwater canyon. This gigantic formation is so huge that it’s
actually only visible in full from space. Amazing, yes? This mega-canyon was discovered in the Bering
Sea and is the deepest underwater canyon known to man. Its volume is a mind-blowing 5,800 cubic kilometers
or 1,400 cubic miles, and it has a depth of 2.6 kilometers or 1.6 miles. To put that into perspective, Zhemchug Canyon
could fit the entire Grand Canyon inside of it! Submarines have traveled through the canyon
and have discovered sea life-galore. But sadly, unless you have a submarine or
a way of traveling to space, you’re just going to have to make do with these images
here. 6. The Antikythera Mechanism
If you haven’t heard of the Antikythera Mechanism – and let’s face it, not many
of us have – it’s an ancient Greek analog computer which was used to predict astronomical
positions and eclipses. The Greeks would then use this information
to create calendars decades in advance. It’s also thought that the computer was
used to track the four-year cycle of the ancient athletic games. When one was found in 1901 by Greek divers,
archeologists around the globe were thrilled to find something dating back so far. It was determined that the instrument was
designed and constructed around 87 BC, and it’s incredible that such an advanced piece
of machinery was developed in ancient times. Makes you wonder what you’ve achieved with
your life really, doesn’t it? No? Just me? Rats. 5. Black Smokers in the Arctic Circle
The last place you’d think to look for boiling water is in the Arctic Sea, but that’s exactly
was found back in 2008. Scientists discovered chimney-like formations
which occur when the icy seawater meets magma, and they behave in the same way that hot springs
do when they shoot water out. The fluids in the chimneys reach temperatures
of 370 degrees Celsius, or 700 degrees Fahrenheit, and are often called Black Smokers because
of the color of the iron sulfide deposits created by the formations. Black Smokers are found around the globe,
but what makes these ones special is that they’re the northernmost examples ever discovered,
and scientists had previously believed that they wouldn’t be able to form in areas with
such slow tectonic plate spreading. This discovery is yet another example of how
mysterious and spectacular our planet is. 4. Blackbeard’s Books
Captain Blackbeard is perhaps the best-known pirate of all time, and so any discovery relating
to him is instantly fascinating. Blackbeard’s ship, the Queen Anne’s Revenge,
was discovered by private salvagers off the coast of North Carolina in 1996, and excavation
began around a year later. Cannons weighing as much as 3,000 pounds were
found, as well as personal items belonging to Blackbeard himself. Fragments from a wet mass of textiles were
taken and cleaned up, and of 16 paper fragments, seven of them contained legible text. A team of people worked out that the page
fragments were from a first edition of Captain Edward Cooke’s book dating back to 1712. Who knew that Blackbeard had time to read
in-between stealing ships, fighting enemies, and other pirate activities? 3. Yonaguni Monument
A giant rock formation off the coast of Japan has scientists baffled, as nobody can figure
out whether or not it’s manmade. Divers found the structure in 1987 and although
it looks as though it must have been constructed by humans, it’s entirely underwater. How would they have managed such a feat? The 3,000-year-old sandstone formation is
connected to the rock beneath it, and the most prominent section of the structure is
almost 500 feet long and 130 feet wide. It’s also 90 feet tall, which creates more
questions surrounding how it could possibly be manmade. Some scientists debate that the structure
was once on dry land, but that an earthquake or erosion must have resulted in it sliding
into the ocean. But, maybe we’ll never know the origins
of the mysterious structure. 2. Lake Michigan Stonehenge
While scouring the depths of Lake Michigan for shipwrecks, archeologists discovered something
much more fascinating. They stumbled upon an incredible underwater
version of Stonehenge. The series of stones arranged in a similar
manner to Stonehenge was also accompanied by a boulder with a prehistoric carving of
a mastodon. This mysterious prehistoric discovery was
found 40 feet into Lake Michigan’s Grand Traverse Bay, and although some of the markings
could easily have been created by nature over the years, it seems as though many of them
were manmade. The discovery could be up to 10,000 years
old, which would coincide with the post-Ice Age presence of humans and mastodons in the
area. Could the stone circle have been used in rituals? What was the purpose of the structure? We may never know, but the thought is truly
fascinating. 1. Baltic Sea Anomaly
Anything with ‘anomaly’ in the title is bound to be cool, right? Well, this finding is no exception to the
rule. Since its discovery by the cool-sounding Ocean
X diving team, researchers around the globe have tried and failed to find an explanation
for the geological feature found on the seabed. The diving team was returning from an expedition
in 2011 when they noticed a blurry but interesting object on the ocean floor. Upon further investigation, the team realized
that they were seeing a crop of land around 60-meters or 200 feet in diameter. The object seems to have stairs and ramps
that could not have been created naturally, and that’s not even the strangest thing
about it. The diving team reported that their technology
malfunctioned around the site and that anything electrical would fail within a 200-meter range. The object is thought by some, including me,
to resemble the Millennium Falcon from the Star Wars films. What do you think?
