Considerable damage is done to roads, airfie lds, bridges, culverts, pipelines and buildings in regions where the ground and the climatological conditions are favorable to ground tree·zil'lg and thawing.

'This , �.. study has boon made. fro m the stand--point of a highway engineer, since the interests of structural engineers and agt'onomists m:ight be somewhat different. The body of the study is divided into s1x chapters.

By definition, the active layer is the layer above permafrost that heat flux, potentially creating tipping point for permafrost thaw freezes and thaws annually. This study, conducted in peatlands of subarctic Canada, in the zone of thawing discontinuous permafrost, demonstrates that the entire thickness of ground atop permafrost does not always refreeze over winter. In these instances, a talik exists between the permafrost and active layer, and ALT Correspondence to: must therefore be measured by the depth of refreeze at the end of winter.

Here including Orthels and Turbels (see definition below). Organic soils: Soils including a large amount of organic carbon (more than 20 percent by weight, Soil Survey Staff, 1999). Here including Histels (see definition below). Gelisols: Soil order in the Soil taxonomy (Soil Survey Staff, 1999). Gelisols include soils of very cold climates, containing permafrost within the first 2m below surface. Gelisols are divided into 3 suborders: Histels: Including large amounts of organic carbon that commonly accumulate under anaerobic conditions (>80 vol % organic carbon from the soil surface to a depth of 50 cm) (Soil Survey Staff, 1999). Turbels: Gelisols that have one or more horizons with evidence of cryoturbation in the form of irregular, broken, or distorted horizon boundaries, involutions, the accumulation of organic matter on top of the permafrost, ice or sand wedges (Soil Survey Staff, 1999).

Hodson1,3, Søren Jessen2, Victor Bense4, Kim Senger1 1Department of Arctic Geology, The University Centre in Svalbard (UNIS), N-9171 Longyearbyen, Norway. 5 2Department of Geosciences and Natural Resource Management, University of Copenhagen, 1350 Copenhagen K, Denmark. 3Department of Environmental Science, Western Norway University of Applied Sciences, N-6856 Sogndal, Norway 4Department of Environmental Sciences, Wageningen University, 6708PB Wageningen, Netherlands. Correspondence to: Mikkel T. Hornum ([email protected]) Abstract 10 In the high Arctic valley of Adventdalen, Svalbard, sub-permafrost groundwater feeds several pingo springs distributed along the valley axis. The driving mechanism for groundwater discharge and associated pingo formation is enigmatic because wet- based glaciers are not present in the adjacent highlands and the presence of continuous permafrost seem to preclude recharge of the sub-permafrost groundwater system by either a sub-glacial source or a precipitation surplus. Since the pingo springs enable methane that has accumulated underneath the permafrost to escape directly to the atmosphere, our limited understanding 15 of the groundwater system brings significant uncertainty to predictions of how methane emissions will respond to changing climate. We address this problem with a new conceptual model for open-system pingo formation wherein pingo growth is sustained by sub-permafrost pressure effects, as related to the expansion of water upon freezing, during millennial scale basal permafrost aggradation. We test the viability of this mechanism for generating groundwater flow with decoupled heat (1D- transient) and groundwater (3D-steady-state) transport modelling experiments.

Abstract In this paper the authors report the vertical bending properties of a test chilled gas pipeline and the countermeasures of the bending. A full-scale field experiment of the chilled gas pipeline system was conducted in Fairbanks, Alaska from 1999 to 2005. The length of the test pipeline was 105m and the diameter was 0.9m. The circulated chilled air was –10oC. One-third of the pipeline was buried in frozen ground and the rest of it was placed in talik.

  • Methane Emissions Proportional to Permafrost Carbon Thawed in Arctic
    LETTERS PUBLISHED ONLINE: 22 AUGUST 2016 | DOI: 10.1038/NGEO2795 Methane emissions proportional to permafrost carbon thawed in Arctic lakes since the 1950s Katey Walter Anthony1*, Ronald Daanen2, Peter Anthony1, Thomas Schneider von Deimling3,4, Chien-Lu Ping5, Jerey P. Chanton6 and Guido Grosse3 Permafrost thaw exposes previously frozen soil organic directly observed old carbon dioxide emission from thermokarst matter to microbial decomposition. This process generates in the unmanipulated upland tundra5; there, multiple decades were methane and carbon dioxide, and thereby fuels a positive required for the loss of old SOC to overcome atmospheric carbon feedback process that leads to further warming and thaw1. uptake from increased plant growth following permafrost thaw. Despite widespread permafrost degradation during the past Scientists have concluded that in most terrestrial environments the 40 years2–4, the degree to which permafrost thaw may be net movement of old carbon from permafrost to the atmosphere contributing∼ to a feedback between warming and thaw in over decades is difficult to detect amidst large input and output recent decades is not well understood. Radiocarbon evidence fluxes from ecosystem carbon exchange5,13. of modern emissions of ancient permafrost carbon is also In contrast to terrestrial environments, thermokarst lakes sparse5. Here we combine radiocarbon dating of lake bubble provide a direct conduit for processing and emission of old trace-gas methane (113 measurements) and soil organic carbon permafrost carbon to the atmosphere, and these emissions are (289 measurements) for lakes in Alaska, Canada, Sweden readily detectable. In ice-rich permafrost regions, permafrost thaw and Siberia with numerical modelling of thaw and remote associated with climate warming leads to ground surface collapse sensing of thermokarst shore expansion.
