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.

Download or read book Canada s Cold Environments written by Hugh M. French and published by McGill-Queen's Press - MQUP. This book was released on 1993 with total page 772 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low temperatures, wind-chill, snow, sea ice, and permafrost have been primary characteristics of Canada's northern and alpine environments during the past two million years. The evolution of Canada's cultural landscapes, the processes of settlement of rural areas, and the present interaction of Canadian industrial society with its biophysical environment are all deeply influenced, directly or indirectly, by the frigidity of the greater part of the country. The phenomenon of global warming, if it occurs, will lessen this coldness, but its impact on temperature extremes, sea ice regimes, vegetation, snow distribution, permafrost, glaciers, lakes, rivers, and mountain hazards are all the subject of intensive research -- the highlights of which are reviewed in Canada's Cold Environments. Eleven of Canada's leading geographers, geologists, and ecologists provide an authoritative yet readable scientific statement about the physical nature of Canada's coldness. They focus on the distinctive attributes of Canada's cold environments, their temporal and spatial variability, and the constraints that coldness places on human activity. The book is aimed at environmental scientists at all levels who need informed overviews of the substantive findings on a range of cold-related topics.

Available in PDF, EPUB and Kindle. Book excerpt: Canadian Geography: A Scholarly Bibliography is a compendium of published works on geographical studies of Canada and its various provinces. It includes works on geographical studies of Canada as a whole, on multiple provinces, and on individual provinces. Works covered include books, monographs, atlases, book chapters, scholarly articles, dissertations, and theses. The contents are organized first by region into main chapters, and then each chapter is divided into sections: General Studies, Cultural and Social Geography, Economic Geography, Historical Geography, Physical Geography, Political Geography, and Urban Geography. Each section is further sub-divided into specific topics within each main subject. All known publications on the geographical studies of Canada—in English, French, and other languages—covering all types of geography are included in this bibliography. It is an essential resource for all researchers, students, teachers, and government officials needing information and references on the varied aspects of the environments and human geographies of Canada.

Download or read book Periglacial Processes and Landforms in Britain and Ireland written by John Boardman and published by Cambridge University Press. This book was released on 2011-04-14 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1987 book examines the intimate link between periglacial geomorphology and the fluctuating climates of the Quaternary Period in the British Isles. In the last two million years, ice sheets have covered northern Britain several times. In the south, at the limit of the glaciation, intense frost action and the formation of permafrost have influenced past and present landscapes. The first part of the book looks at areas of the world that have climates similar to periglacial Britain: Scandinavia, the Canadian Arctic, and alpine regions. Contributors then present data on periglacial landforms in the British Isles. Topics discussed include the periglaciation of upland Britain, ground ice depressions, and pingo remnants. The regions surveyed stretch from northern Scotland to the Isles of Scilly. The contributions are based on a conference held in late 1985 under the sponsorship of the International Geographical Union and the Quaternary Research Association of the United Kingdom.

Available in PDF, EPUB and Kindle. Book excerpt: This volume had its origins in an international symposium organised by the Cold Regions Research Centre, and held at Wilfrid Laurier University in November, 1999. The chapters are modified from a selection of the papers at the meeting, and reflect reviews and revisions in light of discussions then. The original idea for the meeting was to address certain questions that the organisers were encountering in their own work, and that we felt had received limited attention in the recent literature. The two broad issues we wanted to address were: the complex associations of actual landforms and processes in cold regions, and how the almost universal legacies of past, different cold environments of the late Quaternary affect these landscapes in the present. The former involves the problem of identifying landform and sediment complexes, and the interrelations of relevant processes. We sought to identify this in terms oflandform and sediment assemblages appropriate to regional and field-oriented concerns.
Download or read book Thermal Design Considerations in Frozen Ground Engineering written by Thomas G. Krzewinski and published by ASCE Publications. This book was released on 1985-01-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Technical Council on Cold Regions Engineering of ASCE. The design of engineering projects in frozen ground requires thermal design considerations in addition to standard geotechnical design. Factors that influence the thermal characteristics of a site include climatological data, microclimatic characteristics, local hydrology, soil properties, and disturbance. This monograph presents ground temperature observations, procedures for temperature monitoring, analytical methods for ground thermal regime calculations, and ground thermal properties. Active and passive techniques for ground temperature control and ground thawing methods are also presented, followed by case histories of ground temperature effects.
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.
