Book Synopsis Permafrost in Canada by : Roger J.E. Brown
Download or read book Permafrost in Canada written by Roger J.E. Brown and published by University of Toronto Press. This book was released on 1970-12-15 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permafrost is the thermal condition of the earth’s crust when its temperature has been below 32°F continuously for a number of years. Half of Canada’s land surface lies in the permafrost region—either in the continuous zone where the ground is frozen to a depth of hundreds of feet, or in the discontinuous zone where permafrost is thinner, and there are areas of unfrozen ground. The existence of permafrost causes problems for the development of the northern regions of all countries extending into the Arctic. Mining operations are hindered by frozen ore which resists blasting and is difficult to thaw. Agriculture is restricted by the presence of permafrost near the ground surface which limits the soil available for plant growth. Engineering structures are also affected by the low temperatures. Ice layers give soil a rock-like structure with high strength. However heat transmitted by buildings often causes the ice to melt, and the resulting slurry is unable to support the structure. Many settlements in northern Canada have examples of structural damage or failure caused by permafrost. In the construction and maintenance of railways, buildings, water and sewage lines, dams, roads, bridges, and airfields, normal techniques must often be modified at additional cost because of permafrost. For the last twenty-five years scientific investigations and engineering projects have increased steadily in Canada’s permafrost region, and it is now technically possible to build any structure or conduct any activity on the worst soils and under permafrost conditions. This comprehensive analysis of permafrost—its origin, definition, and occurrence, and the effect it has on industry and agriculture—will be invaluable to the growing number of people working in the north and to those interested in its development.
Book Synopsis Permafrost Hydrology by : Ming-ko Woo
Download or read book Permafrost Hydrology written by Ming-ko Woo and published by Springer Science & Business Media. This book was released on 2012-04-14 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permafrost Hydrology systematically elucidates the roles of seasonally and perennially frozen ground on the distribution, storage and flow of water. Cold regions of the World are subject to mounting development which significantly affects the physical environment. Climate change, natural or human-induced, reinforces the impacts. Knowledge of surface and ground water processes operating in permafrost terrain is fundamental to planning, management and conservation. This book is an indispensable reference for libraries and researchers, an information source for practitioners, and a valuable text for training the next generations of cold region scientists and engineers.
Download or read book Geocryology written by Stuart A. Harris and published by CRC Press. This book was released on 2017-09-28 with total page 964 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature.

Book Synopsis Permafrost Response on Economic Development, Environmental Security and Natural Resources by : R. Paepe
Download or read book Permafrost Response on Economic Development, Environmental Security and Natural Resources written by R. Paepe and published by Springer Science & Business Media. This book was released on 2001-04-30 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: The permafrost regions of the planet are remote, barren and isolated; as far as the decision makers are concerned, these inhospitable regions are simply "out of sight, out of mind", having no immediate effect on the global environment and habitat. Those who are pioneering the study of the permafrost, however, know better, as they confront the sustainable development of these peculiarly resource-rich regions. It rapidly became evident that social survival was not merely a matter of technology, and sustainable development involved more than just bringing in adequate machinery. Operating in permafrost regions necessitates a thorough understanding of all aspects of their ecology. This state-of-the-art book on permafrost discusses the topic in terms of geology, biology, chemistry, physics, climatology, engineering, land development, environmental management, social and economic impacts. Topics discussed include on- and offshore data assessment, past and future permafrost evolution according to global climate change, engineering effects on permafrost, and new dimensions in geocryology, including gas hydrates, microbiology, and information technology.

Book Synopsis Origin and Environmental Significance of Large-scale Patterned Ground, Donnelly Dome Area, Alaska by : Richard E. Church
Download or read book Origin and Environmental Significance of Large-scale Patterned Ground, Donnelly Dome Area, Alaska written by Richard E. Church and published by . This book was released on 1965 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-scale patterned ground in the Donnelly Dome area of central Alaska consists of polygons 25 to 46 m in diameter bounded by shallow troughs 1 to 2 m wide that form the sides of the polygons. The troughs are underlain by wedge-shaped masses of sediments that extend downward 2 to 3 m. Texture of the sediments of the wedges is distinct from that of the poorly stratified glacial outwash gravel that the wedges transect. Sediments of the wedge vary texturally along the strike and vertically within a given wedge. The coarsest material in the wedge is about 75 mm in diameter, which is the same size as the coarsest material in the outwash. The fine material in the wedges is silt, the same as that which blankets the area. The patterned ground of the Donnelly Dome area originated during Wisconsin time when the mean annual air temperature was at least 3C colder than now. Wigh the warming of the climate in post-Wisconsin time most of the perennially frozen gravel thawed and the ice wedges melted. The voids created by the melting of the ice wedges were filled with sediment that was washed from the surface or collapsed from the thawed sides of the voids. The troughs bounding the polygons are now, however, no longer underlain with ice wedges but with ice wedge pseudomorphs (fossil ice wedges). (Author).
