The mysterious traces are found at the bottom of the Big Blue Hole, the largest ocean hole in the world, about 60 miles from Belize.
In December last year, a team of researchers, including billionaire Richard Branson and Fabien Cousteau, grandson of French explorer Jacques Cousteau, took part in a mission to dive to the bottom of the hole to find out what was down there. At a depth of more than 1,000 feet and a depth of 410 feet, this is largely an unexplored natural miracle. At the end of the last Ice Age, ice caps melted and sea levels rose, dipping the cave to become what is now the Big Blue Hole.
In November and December last year, the teams made over 20 dives. create a 3D map of it. One of those dives was broadcast live on the Discovery Channel. In it, Branson and Cousteau, led by the pilot of the submarine Erika Bergman, dived into the depths of the hole.
In an interview with CNN Travel, Bergman has talked about what she saw in the Big Blue Hole. He said that at the base of the hole they found unprecedented stalactites: "It was quite exciting because they were not mapped there before, they were not found there before."
Although the water was totally dark, high-resolution sonar equipment on board allowed them to see the hidden features of the formation. "You can be 20 or 30 meters from a stalactite or a piece of a wall and see it in every perfect detail, better than the eyesight even provide," she said, adding that they also found some unknown traces just at the base of the hole ̵
Researchers are now near the completion of the 3D sonar map of the hole. , "It looks really cool, this is this sieve coating, sonar scanning the whole hole a thousand feet in diameter," Bergman said on the website. The Aquatica submarine, which was included in the expedition, said: "The view the map provides is enhanced by other passive environmental data collected from the blue hole submarine. Once processed and collected, this data will be shared with the Belize government and the larger world scientific community as a legacy of the expedition. "Like the mysterious traces, Branson also recently said he found plastic bottles sitting on the bottom of the Big Blue Hole. In a blog post about diving, he writes: "As for mythical monsters from the depths? Well, the real monsters facing the ocean are climate change and plastic. Unfortunately, we saw plastic bottles at the bottom of the hole, which is a real bull of the ocean. We all need to get rid of disposable plastic. "
A documentary on diving by INE Entertainment will be released this spring.
