The deepest, SG-3, reached 12,262 metres (40,230 ft; 7.619 mi) in 1989 and is the deepest artificial point on Earth. In the process, the firm created the “Bertha Rogers hole” – a man-made marvel that reached over 31,400 feet, or nearly six miles, below the surface of the earth. Part of the reason the project — named the “Kola Superdeep Borehole” — wasn’t widely known at the time was because the former Soviet Union initially supervised the operation (located within Russia’s Kola Peninsula), and some details were likely kept under wraps. Then, on June 6, 1979, one of the Kola boreholes, dubbed SG-3, smashed the record. Alicia Ault is a Washington, DC-based journalist whose work has appeared in publications including the New York Times, the Washington Post and Wired. The project to drill into the Earth’s surface began near Murmansk in the 1970s, when Soviet scientists wanted to learn more about the Earth’s crust. The borehole is located on the Kola Peninsula of Russia. Not to be defeated, the researchers abandoned the previous borehole and began again from a depth of 23,000 feet. However, we know more about certain distant galaxies than we do about what lies miles beneath our very own feet.

In 1970, Soviet geologists took on the challenge, setting their drills over the Kola Peninsula, which juts eastward out of the Scandinavian landmass.

The stated areas of study were the deep structure of the Baltic Shield, seismic discontinuities and the thermal regime in the Earth's crust, the physical and chemical composition of the deep crust and the transition from upper to lower crust, lithospheric geophysics, and to create and develop technologies for deep geophysical study. The drilling rig—lost in an explosion in 2010— managed to get some 30,000 feet below the sea, or about 5 miles.

But they gleaned new knowledge about seismic activity and the crust’s composition. 62,700, © 2020 NYP Holdings, Inc. All Rights Reserved 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. “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. [14] The site is still visited by curious sightseers, who have reported that the structure over the borehole has been partially destroyed or removed.[7]. Terms of Use But as we continue to stare skywards in wonder, are we overlooking another equally mysterious world back on Earth? Afterwards, impermeable rocks caused the newly formed water to become trapped beneath the surface. The Kola-92 working group consisted of researchers from the Universities of Glasgow and Edinburgh in Scotland, the University of Wyoming in the United States and the University of Bergen in Norway as well as several Russian earth science research institutions. The quest to drill deeper created a global scientific contest akin to the Space Race. “If we all share in the exploration of our planet, then… we’ll all feel involved in its stewardship for the future.”.

The result was the Kola Superdeep Borehole and a drill-depth of more than 7.5 miles (12 kilometers). However, they soon found that this was not the case – at least not on the Kola Peninsula. That’s the challenge that has been taken up by scientists around the world over the last five decades, with each seeking to drill a hole that will go deeper than before. And by 1983, the hole, a mere nine inches wide, had traveled a staggering 39,000 feet into Earth’s crust. For one thing, the team weren’t certain how the submarines that they intended to use were going to perform under the strain of the deep water. They labeled the creature a Death Star – and with good reason.

Ask Smithsonian: Could the Volcano Beneath Yellowstone National Park Ever Erupt? The effort is expected to take many, if not dozens, of years, and may require $1 billion. But those concerns may have faded away as they began their 3,000-foot descent. [13] In 2008 the Russian InfoCentre announced that the borehole was to be destroyed.

The 40,230ft-deep (12.2km) construction is so deep … And that blood is clear, too, since it doesn’t need the hemoglobin that we humans do to carry oxygen around its body. Their Kola Superdeep Borehole was started in 1970 and still holds the world record for the deepest hole in the ground.

So did we learn anything from these decades of labor? Beginning in the late 1950s, competing teams of American and Soviet scientists began organizing elaborate experiments designed to penetrate Earth’s crust. [1], In terms of true vertical depth, it is the deepest borehole in the world. But the drill bits have a limited lifespan, and high temperatures can deform bits and pipes, not to mention creating a mess out of the bore hole. The borehole is 23 centimetres (9 in) in diameter.

But while some enthusiastic commenters have jumped on this discovery of subterranean water as proof of biblical floods, this phenomenon is believed instead to be the result of strong pressure forcing oxygen and hydrogen atoms out of the rock.

[9], Microscopic plankton fossils were found 6 kilometers (4 mi) below the surface. 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. The crew’s quest to set sail into the unknown has also been recorded in a documentary. Eventually, though, they picked a location called “Iceberg Alley” – and the area hasn’t been given that name without good cause. For the Russian horror film, see, A scientific deep drilling project of the Soviet Union on the Kola Peninsula, Superstructure of the Kola Superdeep Borehole, 2007, German Continental Deep Drilling Programme, "Ask Smithsonian: What's the Deepest Hole Ever Dug? Boreholes were drilled by branching from a central hole. For more than 20 years, the world’s deepest hole could be found on Russia’s Kola peninsula, boring 40,000 feet down into the Earth’s crust. But while they slowly made their way down, prospectors in America had made some progress of their own.

[18], "Kola Superdeep" redirects here. Lots of countries wanted to be the first to drill into the Earth’s mantle during the Cold War and today Japan is attempting to set this record. Essentially, marine snow is organic material that flows from the upper part of the ocean down to the floor. For the next 24 years, they drilled on and off into the Earth’s crust. More often than not, the unlucky victim is a passing krill. Although Lone Star did not find what it was looking for, its effort remained the deepest hole on the planet for another five years. The borehole is 23 centimetres (9 in) in diameter.

The heat wreaks havoc on equipment. When not chasing down a story from our nation's capital, she takes in the food, music and culture of southwest Louisiana from the peaceful perch of her part-time New Orleans home. According to the studies - read that the Russians began this Kola Peninsula deep hole at the middle of the earth. 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. The researchers passed through seismic plates and encountered temperatures as high as 600 degrees F. They managed to get down about six miles before they ran out of funds. “Part of why you’re drilling is because you want to find out what’s down there,” he said. And there’s something else that’s strange about this sunstar. In the past, drillers … Terms of Use

With a depth of 12,262 metres (40,230 ft), it has been since 1989 the deepest artificial point on Earth. Now, the international team that sponsors the Chikyu is endeavoring to top all previous records. And what they discovered down there is an incredible glimpse into a world that no one has ever set eyes on before.
