This book was released on 2000-11 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issue of global warming and climate change is of continuous concern. Since the 1970s, it bas been shown that the pack-ice around the Arctic Ocean is thinning, the margin of permafrost is moving north and the vegetation in the high northern parts of the world is changing (the 'greening' of the Arctic). But are these changes the result of human activity or simply regular variations of the Earth's climate system? Over thousands of years, a continuous archive of iceberg and sea ice drift bas formed in the deep-sea sediments, revealing the place of the ice's origin and allowing a reconstruction of the surface currents and the climate of the past. However, the drift of floating ice from one place to another is not just a passive record of past ocean circulation. It actively influences and changes the surface ocean circulation, thus having a profound effect on climate change. Ice Drift, Ocean Circulation and Climate Change is the first book to focus on the interactions between ice, the ocean and the atmosphere and to describe how these three components of the climate system influence each other. It makes clear the positive contribution of paleoclimatology and paleoceanography and should be read by anyone concerned with global warming and climate change.
Download or read book Glacigenic Sediments written by K. Brodzikowski and published by Elsevier. This book was released on 1990-12-11 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims primarily at providing those involved in fundamental or applied research in the fields of geology, geomorphology and hydrology with a systematic overview of glacigenic sediments. A generally applicable terminology is proposed which should facilitate communication between scientists from several fields. Also it should form a bridge between western and eastern "schools" dealing with Quaternary geology. Because the book is mainly devoted to depositional processes and the resulting deposits, the approach and the terminology followed in this book are obviously founded strongly on sedimentology, the geological discipline that deals specifically with these phenomena.The book will be helpful in describing the sediments involved, interpreting their genesis, establishing their extent and their mutual relationships, and thus in the reconstruction of the palaeogeographic development.The large list of references reflects the author's extensive search of the literature.

This book was released on 1991 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourteen chapters discuss regional stratigraphy by time intervals from Precambrian to Quaternary, while other chapters describe the geography, geomorphology, tectonics, geophysical characteristics, and resources of the region. A summary chapter includes geologic maps, structural cross-sections, a geotectonic correlation chart, a gravity map, and a location map for exploration wells in the Arctic Islands and northern Greenland. A wealth of additional information is contained on the nine accompanying plates.

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 428 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.
Download or read book The Permafrost Environment written by Stuart A. Harris and published by Routledge. This book was released on 2020-03-31 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1986, The Permafrost Environment examines how the search for oil, gas and minerals in the arctic region instigated new and vitally important needs to understand the permafrost environment. The construction of roads, airfields, buildings and pipelines in this inhospitable environment has posed enormous problems for engineers and geologists. This book is a comprehensive review of the nature of the permafrost environment and its utilization. It looks at environmental processes and their effects and examines the management problems which result. It provides a detailed look at how normal procedures for construction etc. need to be modified to cope with the special conditions and it gives examples from throughout the arctic region, including Canada, Siberia, Alaska, Greenland and Northern Scandinavia.
