deepest hole ever made was sealed for this reason

The Kola Superdeep Borehole is 23 centimeters (about 8.7 inches) in diameter and its metal lid is welded on so it is unlikely that anyone would ever fall down it. And while life above the Antarctic waves is harsh and unforgiving, beneath them lies a huge abundance of bizarre, almost otherworldly sea creatures. This water, unlike surface water, must have come from deep-crust minerals and had been unable to reach the surface because of a layer of impermeable rock. However, we know more about certain distant galaxies than we do about what lies miles beneath our very own feet. But as we continue to stare skywards in wonder, are we overlooking another equally mysterious world back on Earth? To scientists, one of the more fascinating findings to emerge from this well is that no transition from granite to basalt was found at the depth of about 7 km (4.3 mi), where the velocity of seismic waves has a discontinuity. Furthermore, diving in the Antarctic is essentially like peering into a window that shows you what life in the seas was like well before humankind ever walked on Earth.

Vote Now! Eventually, though, they picked a location called “Iceberg Alley” – and the area hasn’t been given that name without good cause. And that blood is clear, too, since it doesn’t need the hemoglobin that we humans do to carry oxygen around its body. If you fell down the hole, it would take around 3.5 to 4 minutes to reach the bottom. “It’s the animals without backbones that dominate and that dominate as predators,” said Dr. Copley. Then, however, something unexpected happens, and the researchers are forced to seal up their experiment for good. To put that into some perspective, the average distance between Mars and Earth is 140 million miles. In 1992, although the Russian team was still about 9,000 feet away from their goal, the drilling came to an abrupt end due to dangerous conditions. And beyond the scope for scientific revelations and a better understanding of our own world, there’s perhaps something even more profound about going to a place that’s so hard to reach. “Part of why you’re drilling is because you want to find out what’s down there,” he said. However, in 1992 they had to stop drilling because the temperature was around 180 degrees Celsius (356 Fahrenheit), which was far hotter than the scientists predicted it would be. For 12 months, they paused work on the borehole so that various people could visit the fascinating site. Today, then, the site is flagged as an environmental hazard, although visitors can still see some relics from the experiment in the nearby town of Zapolyarny, some six miles away. All this drilling wasn’t for nothing though as some scientific discoveries were made. And, impressively, researchers have yet to beat its record, meaning the borehole remains the planet’s deepest man-made point. This story has been shared 104,619 times. The project attempted to drill as deep as possible into the Earth's crust. Because the water at the South Pole is so cold, few fish can survive there. “On these dives, we watched the everyday lives of Antarctic deep-sea animals, helping us to understand them much better than studying specimens collected by nets or trawls from ships,” Dr. Copley explained to the BBC. With a depth of 12,262 metres (40,230 ft), it has been since 1989 the deepest artificial point on Earth. But if you think that makes it sound like the dive under the Antarctic was simple, then you’re very wrong. The project was officially terminated in 1995, due to the dissolution of the Soviet Union, and the site has since been abandoned. The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. By measuring seismic waves, experts had previously predicted that the rock under our feet shifts from granite to basalt at around two to four miles beneath the surface. For example, at some four miles deep, they discovered tiny fossils of marine plants. Krill are tiny crustaceans that live throughout our planet’s oceans and play an important role there. For the first 10,000 feet, temperatures inside the borehole had more or less adhered to what the researchers had expected to find. Ask Smithsonian: Will the Leaning Tower of Pisa Ever Topple? Chikyu is capable of carrying up to 6 miles of drill pipes at a time. But that wasn’t it, either. It’s a hugely important source of food for creatures that live in the deep, as it transfers nutrients and energy from the parts of the sea that receive sunlight to the areas of the ocean that don’t. “If we have a better knowledge of what the mantle is and how the mantle behaves, we have better knowledge of volcanoes and earthquakes, and better knowledge of how the planet as a whole works,” said Benjamin Andrews, a research geologist and a curator for the National Rock and Ore Collection at the Smithsonian's National Museum of Natural History.
