Divers exploring Belize’s iconic Great Blue Hole made a shocking discovery that alerted people to the state of our planet, as well as more hidden secrets.

The Great Blue Hole is an expansive marine sinkhole lurking off the Belizean coast, stretching a staggering 318 meters (approximately 1043 feet) across and plunging 124 meters (about 407 feet) deep.

In 2018, an expedition, backed by billionaire tycoon Richard Branson, dared to explore the enigma of the Great Blue Hole. Although completed in 2018, this daring venture has recently resurfaced, captivating audiences anew with its startling revelation about our human footprint.

As reported by the New York Post, a team from Aquatica Submarines embarked on a descent to fathom the depths of the Blue Hole. Their intention was to chart a comprehensive 3D map of the sinkhole's interior. However, as they delved deeper, an unsettling spectacle awaited them.

During their descent, which included the intrepid Branson himself, the crew was treated to visits from marine life – sea turtles, reef sharks, and majestic corals. Yet, as they approached the 90-meter (295-foot) mark, a sense of foreboding descended along with them.

Erika Bergman, a member of the expedition, recounted their encounter with a noxious layer of toxic hydrogen sulfide, effectively sealing off deeper access and cutting off the oxygen supply.

"We found conchs and conch shells and hermit crabs that had fallen into the hole and suffocated," she said.

Amidst the discovery, the team stumbled upon a two-liter Coke bottle, venturing an astonishing 407 feet below the surface, and a lost GoPro camera still full of a holidaymaker's photos.

Amidst the debris, lay the remains of two human divers, believed to be those who vanished during a previous expedition. A poignant decision was made not to disturb their resting place. As Bergman stated: "It’s very dark and peaceful down there, just kind of let them stay," while adding that the team let the Belize government know about the bodies.

Not everything was so grim, as the expedition unveiled ancient stalactites, reminiscent of icicles adorning the ceilings of caves. This stunning discovery painted a vivid portrait of the Great Blue Hole's past - a time when it was a dry cave, teeming with prehistoric life.

Scientists believe that the cavity was born during the waning days of the last Ice Age, some 14,000 years ago. As the Ice Age's grip loosened, and the seas rose, the cave eventually succumbed to the rising water levels.

Sadly, it seems as though the Great Blue Hole won't be around forever as daily cascades of sand tumble into the chasm, meaning that it might one day fill up.

Branson, the driving force behind the exploration, noted that it drew attention to the climate crisis. Describing the expedition as "one of the starkest reminders of the danger of climate change [he had] ever seen," Branson underscored the vital importance of recognizing humanity's impact.

"The Blue Hole is made of a complex system of caves that once formed on dry land. It is proof of how oceans can rise quickly and catastrophically," Branson said.

"The real monsters facing the ocean are climate change - and plastic. Sadly, we saw plastic bottles at the bottom of the hole, which is a real scourge of the ocean. We’ve all got to get rid of single-use plastic."

The Great Blue Hole, a marine marvel off the coast of Belize, has always been shrouded in mystery and allure. This massive underwater sinkhole spans an impressive 1,043 feet in diameter and plunges to depths of 407 feet.

But in 2018, an exploration team sponsored by none other than billionaire Richard Branson delved into this enigmatic abyss. What they found not only astounded the scientific community but also sent a harrowing message about the state of our planet.

As the New York Post reported, a specialized team from Aquatica Submarines took on the audacious task of creating a comprehensive 3D map of the Great Blue Hole's interior. Featuring aquatic celebrities like reef sharks, sea turtles, and colorful corals, the team initially enjoyed the natural beauty the sinkhole offered. However, the charm faded as they neared the 295-foot mark.

Erika Bergman, a key member of the expedition, described encountering a "noxious layer of toxic hydrogen sulfide" at this depth. "We found conchs and conch shells and hermit crabs that had fallen into the hole and suffocated," she revealed.

The dive took a darker turn when amidst the ancient stalactites—painting a vivid portrait of a time when this underwater cave was a dry haven teeming with prehistoric life—the team discovered contemporary garbage.

A two-liter Coke bottle and a GoPro camera full of vacation photos lay at an astonishing depth of 407 feet, alarmingly close to the skeletal remains of two divers from a previous expedition.

"It’s very dark and peaceful down there, just kind of let them stay," said Bergman, noting that they had informed the Belize government about the human remains.

Backed by Branson, who described the expedition as "one of the starkest reminders of the danger of climate change [he had] ever seen," the adventure took on a larger meaning. "The Blue Hole is made of a complex system of caves that once formed on dry land. It is proof of how oceans can rise quickly and catastrophically," Branson emphasized.

Scientists suggest that the Great Blue Hole was formed approximately 14,000 years ago during the last days of the Ice Age. As the frozen world melted and sea levels rose, the dry cave was eventually inundated. Today, it's a time capsule that's degrading fast as sand constantly cascades into the depths, threatening to one day fill it up completely.

"The real monsters facing the ocean are climate change - and plastic," Branson lamented. "Sadly, we saw plastic bottles at the bottom of the hole, which is a real scourge of the ocean. We’ve all got to get rid of single-use plastic."

This chilling dive into the heart of Belize's Great Blue Hole serves as an urgent wake-up call, highlighting not just the wonders of our natural world but the frightening pace at which it's being compromised. As this once-hidden treasure reveals its untold secrets, it also exposes the urgent need for environmental stewardship. Will we heed its warning in time?

An underwater drone captured terrifying footage after reaching the bottom of the Great Blue Hole.

The famous marine sinkhole, located about 60 miles off the coast of Belize, has long been considered one of the most feared and interesting dive spots on the planet.

From the surface, it’s a near-perfect sapphire circle, but beneath the surface lies a darker, more dangerous reality.

Over the years, explorers have sent drones, submarines, and divers into the void, uncovering everything from human remains and lost GoPros to plastic waste and lifeless zones beyond a toxic gas layer.

YouTuber’s Mission

Most recently, YouTuber Will Mitchell attempted to reach the bottom of the 124-metre-deep hole using a weighted underwater drone rigged with a GoPro.

The mission started out smooth, with the camera capturing bright blue water, curious marine life, and the occasional shark gliding past. But that calm didn’t last.

As the drone continued its descent, a shark suddenly vanished from view - only to return with full force. It charged directly at the device, violently smashing into it and sending the footage into a chaotic spin.

“The shark just blitzed us!” Mitchell shouted in shock.

The shark eventually disappeared into the darkness, leaving behind only shaky footage and rattled nerves. Fortunately, the equipment survived - but what came next was even more disturbing.

A Lifeless Graveyard

Around 90 metres down, the camera went through a thick layer of hydrogen sulphide, a toxic gas that blocks oxygen and sunlight. Below that, everything was dead.

Above the layer, there were fish and other sea life. But under it, there was nothing - no light, no movement, just the outlines of dead creatures in a dark underwater graveyard.

Scientists say this deadly zone is also like a time capsule, with layers of untouched history.

In 2022, scientists from Goethe University Frankfurt studied how the hole was formed and looked at its sediment layers, which have stayed mostly untouched because of the area’s special conditions, like layered water and a lack of oxygen.

“Inside the sediment core, they look a bit like tree rings,” said Dr. Dominik Schmitt, who led the research team.

Their findings revealed that roughly 574 storm events have hit the area in the last 5,700 years. But that number could spike dramatically in the coming decades.

Professor Eberhard Gischler warned: “Our results suggest that some 45 tropical storms and hurricanes could pass over this region in our century alone. This would far exceed the natural variability of the past millennia."

Scientists have made a stunning discovery after they uncovered 100 new species off of the coast of New Zealand and an entirely new life form.

The Ocean Census, launched last April, has set an ambitious goal to identify 100,000 unknown species within the next decade, aiming to shed light on the mysteries lurking in the ocean depths, as reported by CNN.

During a three-week expedition in February aboard the research vessel Tangaroa, the team collected nearly 1,800 samples from depths as far down as three miles below the surface.

The team employed various types of sleds modified for different terrains, including a beam trawl, a seamount sled, and a specialized device for sampling just above the seafloor.

Regarding the incredible new find, the researchers mistook it for a sea star or sea anemone, though those working along the expansive 500-mile-long Bounty Trough now speculate it might be an entirely new species of deep-sea coral.

Dr. Michela Mitchell, a taxonomist at the Queensland Museum Network, expressed her excitement, stating: "Even more excitingly, it could be a whole new group outside of the octocoral. If it is, that is a significant find for the deep sea and gives us a much clearer picture of the planet’s unique biodiversity."

The discovery has left scientists scratching their heads. "It is still a mystery. We can’t even describe it to family. We don’t know where it is in the tree (of life) as of yet, so that’ll be interesting," said Dr. Daniel Moore of the Ocean Census.

"It was true exploration, very exciting," Moore exclaimed.

In addition to the potentially groundbreaking discovery of the deep-sea coral, the team also encountered a new species of fish, identified as an eelpout.

"The eelpout was instantly recognized as being different from the others," Moore explained.

Commenting on the rarity of discovering new vertebrates, Moore stated: "Finding new vertebrates is rare. There are hundreds of thousands of invertebrates in the sea that we still don’t know. Vertebrates, we like to think that we know what’s out there, but the reality is, we just don’t."

Despite these remarkable discoveries, the vast majority of the ocean remains unexplored. According to the Ocean Census, of the estimated 2.2 million species believed to inhabit its watery depths, only about 240,000 have been cataloged by scientists.

This isn't the only recent remarkable discovery, as a group led by Dr. Javier Sellanes of the Universidad Católica del Norte off the coast of Chile believes they've discovered over 100 new species.

Dr. Javier Sellanes told Schmidt Ocean: "We far exceeded our hopes on this expedition. You always expect to find new species in these remote and poorly explored areas, but the amount we found, especially for some groups like sponges, is mind-blowing.

"These thriving and healthy ecosystems indicate that the Nazca-Desventuradas and Juan Fernández Marine Parks effectively protect delicate marine habitats."

Who knows what sea creatures are lurking down there... it's no wonder some people have a fear of the ocean!

This is one of those stories that reminds you just how incredible nature is.

A strikingly beautiful pink manta ray - believed to be the rarest in the world due to its unique coloring - has been photographed off the Great Barrier Reef near Lady Elliot Island, Australia.

In a moment that I can only compare to that time I caught a shiny Matine in Pokémon Gold, the stunning images were captured by Finnish underwater photographer Kristian Laine, and were later shared to his social media accounts.

The spectacular creature has been named Inspector Clouseau by experts, after the detective from the Pink Panther series.

You never know what nature is going to throw up. This is the moment a fish with a "human face" was spotted in China:

According to National Geographic, the 11-foot Inspector Clouseau was first spotted back in 2015, and the pink giant has been seen fewer than 10 times since.

Sharing the images with his 13,000 Instagram followers, Laine captioned the image: "[The world's] only pink manta called Inspector Clouseau. What an amazing and absolutely unforgettable encounter that was. Stay tuned for more photos to come of this beautiful mantas little adventures at Lady Elliot Island".

In an interview with Angela Heathcote at Australian Geographic, Laine said: "At first I was very confused. I actually thought my strobes were playing up."

The photographer shared more pictures of the incredible ocean dweller on Monday, along with the caption: "Its pink manta kind of monday today. The only pink manta in the whole world can be found cruising the shallow waters around lady elliot from time to time, around 8 times in 8 years i think is more like the odds [sic]"

Per National Geographic, Project MANTA - a multidisciplinary study of manta rays established back in 2007 - says the leading theory is that Inspector Clouseau has a genetic mutation in its expression of melanin, or pigment, says Asia Haines, a research assistant for the group.

Smithsonian Magazine states: "Such mutations are fairly common in the animal world, including among fish, as well as humans with albinism."

Writing on his official photography website, KristianLainePhotography.com, Kristian says his love of water came when he was just nine months old, when his mom was bathing him. Laine recalls that he "started diving like a fish and never stopped".

Laine then found a love for snorkeling when his family would travel to Spain, and would later move to the Australian Gold Coast, where he fell in love with surfing. However, after a back injury left him unable to surf anymore, Laine says he became obsessed with nature in Queensland, and started to take pictures during weekend hikes.

It was after he saw a "cool photo of a turtle" that Kristian "knew he needed to start underwater photography".
