, 2008 Significant numbers of viable ancient microorganisms are known to be present within the permafrost. They have been isolated in both polar regions from the cores up to 400 m deep and ground temperatures of -27 C. The age of the cells corresponds to the longevity of the permanently frozen state of the soils, with the oldest cells dating back to {approx}3

AbstractData from Yakutia, Siberia, indicate that permafrost has been generally stable for the last 300,000 years. Historic records indicate climatic variability in the last 150 years and predict that, in comparison with the 1980s, winters will be colder and summers warmer in the early part of the twenty‐first century.

Journal of Cold Regions Engineering, 1987 Piles have been installed in permafrost in the northern hemisphere for various engineering purposes. To date, there is a large amount of published information on piles in permafrost which has led to accepted design practices. However, there are no standards for designing or testing piles.

Hydrogenotrophic and acetoclastic methanogenesis was measured at temperatures between 5 and -16.5 degrees C with H14CO3- and 14CH3CO2- as substrates in Siberian permafrost soils. The rate of methane formation was reduced approximately 2-fold over the temperature range from 5 to -1.8 degrees C.
