All Eyes on Lake Vostok...To Be Breached Today!!! | |
Anonymous Coward User ID: 1511582 United States 01/18/2012 07:49 PM Report Abusive Post Report Copyright Violation | This story seems weird to me. I don't pretend to know anything about drilling at those depths but why does it take 24 hours to drill down just 2 meters in ice? I guess I could see if it were solid rock or something like that but ice? Heck my little ice auger can cut an 8" hole through 24 inches of ice in under a minute. Also, at those depths, why wouldn't the water pressure break the remaining ice at the bottom of the hole? Quoting: Hawgzilla Anyone know the answers to these questions? The water pressure will eventually help break the ice remaining at the bottom. In fact, the pressure being released has been discussed amongst the scientist who are working on this and other drillings happening in antarctica. They have hypthosiezed that pressure being released could throw off the balance of the ice sheet creating "unknown damage." Lake Vostok is not an isolated lake. There is a massive network of subterranean lakes including Vostok. But anyway.. at the end of Lake Vostok is what’s known as a gigantic masscon—a mass concentration of metal, very similar to the masscons they discovered on the Moon — a gigantic, circular-shaped, metallic object deep under the ice at the end of Lake Vostok. So between the "unknown damage" this could create and the masscon there has been quite a few delays in the prusuit of this objective. -- But it is our opinion that what they are doing now, right now, is rushed. The objectives a few are prusuing may have direct consequences to the many. The Russians have been drilling for years at that location. Think they will think twice now? Doubtful, I sure hope they have covered all scenarios! they are in the dark. [link to www.bbc.co.uk] From article: "We don't know what awaits us down there," he said, adding that personnel at the station have been working shifts, drilling 24 hours a day. Overlaid by nearly 4km of ice, it has been isolated from the rest of the world for millions of years. Some scientists think the ice cap above and at the edges has created a hydrostatic seal with the surface, preventing lake water from escaping or anything else from getting inside. >>>>> It was at the Vostok station that the coldest temperature ever found on Earth (-89°C) was recorded on 21 July 1983. Normally, water in such extreme conditions exists only in one state: ice. And when, in the 1970s British scientists in Antarctica received strange radar readings at the site, the presence of a liquid, freshwater lake below the ice did not instantly spring to mind. >>>> Up until three km down, drilling is usually relatively easy - it has been done in Greenland and here in Antarctica. But after three km and as we near the bottom [of the ice sheet], the ice temperature gets very close to the ice melting point, and all sorts of problems begin," said Dr Ekaikin. >>> But the Russians working in Antarctica believe that the risks are virtually non existent and that the possibility of a great discovery makes it entirely worthwhile. In 2006, researchers reported evidence for a network of rivers under the ice which connect Antarctica's sub-glacial lakes. Some scientists think this could spell trouble for the prospects of finding microbial life that has evolved "independently". ------- They are doing not thinking.. surprised? Imagine if the earth was sentient being, we are poking away at the last sacred untouched spot in the name of DISCOVERY. Is it high pressure that is keeping it liquified? Also, is the masscon highly magnetized? If so, then at one point in its life it was exposed to vast amounts of energy (charge/electricity). kori |

El Quisqueyano User ID: 9030729 United States 01/18/2012 08:24 PM Report Abusive Post Report Copyright Violation | This week, a Russian team drilling into Lake Vostok in the center of the Antarctic continent is likely to break through the ice to water. It will be the first time that a subglacial lake has been breached. These modern-day explorers hope to discover whether Vostok, which at 5000 km 3 is the third largest lake on the planet, is teeming with hidden, cold-loving life that could have evolved separately from the rest of the world for hundreds of thousands of years. Quoting: RazorX 1378340 Microbiologist John Priscu of Montana State University in Bozeman, who was one of the original planners of the Vostok mission, has been getting regular updates from the Russian team. As of 13 January, they had reached a depth of 3737.5 meters, about 15 meters away from liquid water. With three teams drilling around the clock and making progress at an average of 2 meters per day, Priscu says they're on track to break through within the week. "This is an epic event. I really wish them luck," he says. "I wish I was out there with them." After drilling 3720 meters last February, time ran out for the team and the project was stymied just 29.5 meters from its destination as winter set in. Over the summer, they modified their drill bits and now the team is back at work with plenty of time to spare. They had left the large hole filled with antifreeze, so it was ready and waiting for them. It will remain open for years to come, Priscu says, potentially allowing other teams to sample the waters in the future. It's a nerve-wracking moment for the drillers, however. The lake water is under immense pressure, making it imperative that the team's calculations are correct. In the worst case scenario, Priscu says, "water could come up the hole and degas explosively, blowing out the whole borehole." [link to news.sciencemag.org] Obviously, this is uncharted territory, a first for mankind. sounds like many things could go wrong. I wish them all the best! This is incredible news! For 14 millian years it has been sealed under the ice. If life exists in Lake Vostok it will further the evidence that life can exist elsewhere in the cosmos, such as Jupiter's moon Europa and beyond. If the Russians stay on schedule, they should breach the lake by tomorrow! I can't wait to hear about their findings. RazorX Will they do a Live stream?

Does the ice regenerate itself, faster then it can melt, does it create a barrier of imovable object, and irrisistable force? Are the magnetics of the mascon at play to keep a barrier around the lake, preventing the temp of the lake from consuming the glacier?

Anonymous Coward (OP) User ID: 1378340 United States 01/18/2012 08:45 PM Report Abusive Post Report Copyright Violation | Interesting articles here too. [link to s8int.com] Lake Vostok is located 2.48 miles (four kilometers) beneath the East Antarctic Ice Sheet. The lake, and more than 70 other lakes deep beneath the polar plateau, are part of a large, sub-glacial environment that has been isolated from the atmosphere since Antarctica became covered with ice more than 15 million years ago. Moffett Field - Aug 12, 2003 Water released from Lake Vostok, deep beneath the south polar ice sheet, could gush like a popped can of soda if not contained, opening the lake to possible contamination and posing a potential health hazard to NASA and university researchers. A team of scientists that recently investigated the levels of dissolved gases in the remote Antarctic lake found the concentrations of gas in the lake water were much higher than expected, measuring 2.65 quarts (2.5 liters) of nitrogen and oxygen per 2.2 pounds (1 kilogram) of water. According to scientists, this high ratio of gases trapped under the ice will cause a gas-driven "fizz" when the water is released. "Our research suggests that U.S. and Russian teams studying the lake should be careful when drilling because high gas concentrations could make the water unstable and potentially dangerous," said Dr. Chris McKay of NASA's Ames Research Center in California's Silicon Valley. Serious doom potential! |

The water in the Lake (determined by surface thermal scans) ranges from 50 to 65 degrees F, clearly indicating a sub-terranean heat source.

As a satellite passes 50 or 60 miles overhead, the mascons pull it forward, back, left, right, or down, the exact direction and magnitude of the tugging depends on the satellite's trajectory. Absent any periodic boosts from onboard rockets to correct the orbit, most satellites released into low lunar orbits (under about 60 miles or 100 km) will eventually crash into the Moon. PFS-2 released by Apollo 16 was simply a dramatic worst-case example. But even its longer-lived predecessor PFS-1 (released by Apollo 15) literally bit the dust in January 1973 after less than a year and a half. |

But after three km and as we near the bottom [of the ice sheet], the ice temperature gets very close to the ice melting point, and all sorts of problems begin," said Dr Ekaikin. >>> But the Russians working in Antarctica believe that the risks are virtually non existent and that the possibility of a great discovery makes it entirely worthwhile. In 2006, researchers reported evidence for a network of rivers under the ice which connect Antarctica's sub-glacial lakes. Some scientists think this could spell trouble for the prospects of finding microbial life that has evolved "independently". ------- They are doing not thinking.. surprised? Imagine if the earth was sentient being, we are poking away at the last sacred untouched spot in the name of DISCOVERY. Is it high pressure that is keeping it liquified? Also, is the masscon highly magnetized? If so, then at one point in its life it was exposed to vast amounts of energy (charge/electricity). kori Ss I read somewhere the reason, but my internet is down and I can't look up the sources as easily on my phone. But, im sure you can find the answer on the net, well at least theories. Yes I believe there is something to the idea that masscon is magnetised. [link to science.nasa.gov] Lunar mascons make most low lunar orbits unstable," says Konopliv. As a satellite passes 50 or 60 miles overhead, the mascons pull it forward, back, left, right, or down, the exact direction and magnitude of the tugging depends on the satellite's trajectory. Absent any periodic boosts from onboard rockets to correct the orbit, most satellites released into low lunar orbits (under about 60 miles or 100 km) will eventually crash into the Moon. PFS-2 released by Apollo 16 was simply a dramatic worst-case example. But even its longer-lived predecessor PFS-1 (released by Apollo 15) literally bit the dust in January 1973 after less than a year and a half. From what I read it is highly magnetised. So much so, our satellites picked it up. This mascon is huge though, roughly 65 miles square. Wow! |

I don't pretend to know anything about drilling at those depths but why does it take 24 hours to drill down just 2 meters in ice? I guess I could see if it were solid rock or something like that but ice? Heck my little ice auger can cut an 8" hole through 24 inches of ice in under a minute. Quoting: Hawgzilla I thought the same thing, Kilometers, maybe? |
