Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Army Cold Regions Research and Engineering Laboratory's permafrost tunnel at Fox, near Fairbanks, Alaska, was used to investigate the sublimation process in permafrost silt. The rate of increase in thickness of the dried silt layer from sublimation was found to be approximately 0.023 in. (0.058 cm) in 1 month and closely related to the relative humidity in the tunnel. Sublimation prevention studies consisted of evaluation of various membranes to impede the sublimation. Ice was found to show promise as an easily installed, effective membrane when applied as a fine water mist and subsequently left to freeze. (Author).
Download or read book Preparation and Description of a Research Geophysical Borehole Site Containing Massive Ground Ice Near Fairbanks Alaska written by Allan J. Delaney and published by . This book was released on 1987 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A geophysical control site consisting of 27 holes drilled in permafrost and cased with ABS pipe has been completed near the USACRREL permafrost tunnel at Fox, Alaska. The site provides excellent control on a range of material types in permafrost terrain including frozen silt, gravel, bedrock, and all common ground-ice types such as wedge, lens, and pore ice. The holes delineate massive ground-ice features of which there is no surface manifestation. Ground temperature data is available from a small-diameter glycol-filled hole. This report describes the site, its preparation, and the soil logs and data obtained. Keywords: Drilling equipment; Ground-ice; Ground temperature.

This book was released on 1972 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Army Cold Regions Research and Engineering Laboratory (USA CRREL) permafrost tunnel near Fiarbanks, Alaska, was recently enlarged. A new winze and lower room were constructed in the tunnel, permitting examination of new silt exposures and previously unexposed, stratigraphically lower gravels and bedrock. From these exposures additional stratigraphic information was obtained by radiocarbon dating; new data on the material properties of the perennially frozen gravels were also acquired. (Author).

This book was released on 2012-12-06 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike connotations such as greenhouse effect. global change, sea level, desertification, etc. , permafrost is definitely lacking in the everyday speech of many non-specialists. The reason is that areas of permafrost are too remote, barren and isolated. Focus on permafrost today is brought when huge environmental disasters, mainly related to pollution by oil spills, occur. Even then it is offered as
Download or read book Feasibility of Tunnel Detection by Trace Gas Analysis written by R. P. Murrmann and published by . This book was released on 1970 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of tunnel detection by trace gas analysis was investigated at the USA CRREL permafrost tunnel near Fox, Alaska. Under favorable conditions, the presence of an odor unique to the tunnel could be sensed at least 200 yards downwind from the air vent. Under extremely unfavorable conditions, trace gases identified in the tunnel were present 40 years downwind from the air vent in concentrations 10 to 100 times greater than were observed upwind. These results supported the principle of detection by trace gas analysis. (Author).

Download or read book Ice marginal and Periglacial Processes and Sediments written by Ireneo Peter Martini and published by Geological Society of London. This book was released on 2011 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the sediments deposited by glaciers or other cold-climate processes assumes enhanced significance in the context of current global warming and the predicted melt and retreat of glaciers and ice sheets. This volume analyses glacial, proglacial and periglacial settings. Papers include topics such as sedimentation at termini of tidewater glaciers, poorly understood high-mountain features, and slope and aeolian deposits that have been sourced in glacial and periglacial regions and subsequently transported and deposited by azonal processes. Difficulties encountered in inferring Pleistocene and pre-Pleistocene cold-climate conditions when the sedimentary record lacks specific diagnostic indicators are discussed. The main objective of this volume is to establish the validity and limitations of the evidence that is used to achieve reliable palaeogeographic and palaeoclimatic reconstructions. On the much longer geological timescale, an understanding of ice-marginal and periglacial environments may better prepare us for the unavoidable reversal towards cooler and perhaps even glacial times in the future.

Download or read book The Periglacial Environment written by Hugh M. French and published by John Wiley & Sons. This book was released on 2017-10-27 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Periglacial Environment, Fourth Edition, is an authoritative overview of the world’s cold, non-glacial environments. First published in 1976 and subsequently revised in 1996 and 2007, the text has been the international standard for nearly 40 years. The Fourth Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes and landforms that characterize periglacial environments. Part One discusses the periglacial concept and describes the typical climates and ecosystems that are involved. Part Two describes the geocryology (permafrost science) associated with frozen ground. Part Three outlines the weathering and geomorphic processes associated with cold-climate conditions. Part Four provides insight into the periglacial environments of the Quaternary, especially the Late Pleistocene. Part Five describes some of the problems associated with human occupancy in regions that experience frozen ground and cold-climate conditions. Extensively revised and updated Written by an expert with over 50 years of field research Draws upon the author’s personal experience from Northern Canada, Alaska, Siberia, Tibet, Antarctica, Svalbard, Scandinavia, southern South America, Western Europe and eastern North America This book is an invaluable reference for advanced undergraduates in geography, geology, earth sciences and environmental sciences programs, and to resource managers and geotechnical engineers interested in cold regions.
