The earth’s cryosphere, which includes snow, glaciers, ice caps, ice sheets, ice shelves, sea ice, river and lake ice, and permafrost, contains about 75% of the earth’s fresh water. It exists at almost all latitudes, from the tropics to the poles, and plays a vital role in controlling the global climate system. It also provides direct visible evidence of the effect of climate change, and, therefore, requires proper understanding of its complex dynamics. This encyclopedia mainly focuses on the various aspects of snow, ice and glaciers, but also covers other cryospheric branches, and provides up-to-date information and basic concepts on relevant topics. It includes alphabetically arranged and professionally written, comprehensive and authoritative academic articles by well-known international experts in individual fields. The encyclopedia contains a broad spectrum of topics, ranging from the atmospheric processes responsible for snow formation; transformation of snow to ice and changes in their properties; classification of ice and glaciers and their worldwide distribution; glaciation and ice ages; glacier dynamics; glacier surface and subsurface characteristics; geomorphic processes and landscape formation; hydrology and sedimentary systems; permafrost degradation; hazards caused by cryospheric changes; and trends of glacier retreat on the global scale along with the impact of climate change. This book can serve as a source of reference at the undergraduate and graduate level and help to better understand snow, ice and glaciers. It will also be an indispensable tool containing specialized literature for geologists, geographers, climatologists, hydrologists, and water resources engineers; as well as for those who are engaged in the practice of agricultural and civil engineering, earth sciences, environmental sciences and engineering, ecosystem management, and other relevant subjects.

This book is a comprehensive overview of the ever-captivating field of glaciation from the perspective of glacial landsystems. This approach models the many processes, forms and interactions that can be found in glaciated landscapes throughout the world. Landsystems models allow the glacial geologist and geomorphologist to evaluate these landscapes in relation to the dynamics of glaciation and to climate and geology. Glacial Landsystems brings together the expertise of an international range of specialists to provide an up-to-date summary of landsystems relevant to both modern and ancient glacier systems and also in the reconstruction and interpretation of former glacial environments. The models are applicable at all scales from ice sheets to small valley glaciers. This book is an essential reference for anyone embarking upon research or engineering surveys in glaciated basins and provides a wide-ranging handbook of glacial landsystem types for students of glaciation.

Glaciated Coasts is a collection of articles that deals with shoreline morphologies of glaciated coasts and the processes that formed these coastlines in North America. This book examines nonsandy shorelines and covers a range of geologic and geographic coastal settings in a northern-southern order. This text investigates and compares the glaciated northern shorelines. These shorelines north of the glacial limit are mostly of the primary form in different stages of modification by marine agents. Shorelines are associated with embayments; baymouth barriers in turn enclose embayments. This book describes beaches as having coarse or mixed sediment populations. Most beaches worldwide have gravel clasts that have been rounded and sorted by marine processes. In the southeastern coast of Alaska, active tectonics on a mountainous shoreline is evident. The region also shows emergent and submerging shorelines with a glacial imprint undergoing formation by modern processes. This book also gives examples of gravel beach environments in various coastal settings. This book can prove useful for students of meteorology, oceanography as well as to marine ecologists and biologists. It can also benefit readers whose interest lie with coastal environment or with the general earth sciences.

Iceland provides an unique stage on which to study the natural environment, both past and present, and it is understanding both aspects of reconstructing the past and observing and interpreting the present that form the focus of the contributions to this volume. The papers are all written by active researchers and incorporate both reviews and new data. Although concentrating largely on the recent Quaternary timescale a wide range of topics is explored including subglacial volcanism, onshore and offshore evidence for the Last Glacial Maximum and subsequent deglaciation, current glacial characteristics including jökulhlaups and glacial landsystems, soil development, Holocene ecosystem change, current oceanography, impacts of volcanic sulphur loading, chemical weathering and the CO2 budget and documentary evidence for historical climate. The key element of the volume is that for the first time it provides a wide overview of a range of topics for which Iceland provides an almost unparalleled laboratory emphasizing the importance of research on this small island for studies over a much broader global scale. These reviews point the way to future research directions and are supplemented by extensive illustrations and a comprehensive bibliography. * Wide range of related topics covered both from a present day and quaternary perspective * Reviews from scientists active in each research area across a range of subjects providing both overviews and new data supplemented by an extensive bibliography * Extensive illustrations and examples from the field

Sediments are the most valuable form of physical evidence for past Earth surface processes. They have the potential to build up an archive of events and provide a window into the past. Through careful examination of sediments the shifting patterns of surface processes across space and time are revealed, allowing us to reconstruct past environments and environmental change. A Practical Guide to the Study of Glacial Sediments is a guide to the standard techniques employed to read the sedimentary record of former glaciers and ice sheets. It demonstrates that the often complex and fragmentary glacial sedimentary record can, when examined systematically and rationally, provide detailed insights into former environments and climates in places where no other evidence is available. The complementary techniques covered in this book include: facies description, grain size analysis, clast form assessment, clast macrofabric analysis, micromorphology, particle lithology and assessment of engineering properties. They yield consistent and meaningful results in a range of glacial depositional environments throughout the world, from the high Arctic to the Himalayas. A Practical Guide to the Study of Glacial Sediments provides students and researchers with a clear and accessible guide to recording and interpreting glacial successions wherever the location.

Periglacial and Paraglacial Processes and Environments

Author: Stephan Harrison

Publisher: Geological Society of London

ISBN: 9781862392816

Category: Science

Page: 272

View: 3982

Periglacial and paraglacial environments, located outside ice sheet margins but responding to similar climate forcings, are key to identifying climate change effects upon the Earth system. These environments are relicts of cold Earth processes and so are most sensitive to global warming. Changes in the distribution and thickness of permafrost in continental interiors have implications for ecosystem and landscape stability. Periglacial Alpine environments are experiencing increased rockfall and mass movement, leading to rock glacier instability and sediment release to downstream rivers. In turn, these landscape effects impact on natural hazards and human activities in these sensitive and geologically transient environments.

Periglacial Processes and Landforms in Britain and Ireland

Author: John Boardman

Publisher: Cambridge University Press

ISBN: 9780521169127

Category: Science

Page: 308

View: 7423

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.

The current volume provides examples of how environmental hazards such as landslides, earthquakes, mountain processes, cold climate processes and tidal flows and currents can affect the energy supply infrastructure. In times of uncertainty, the security of the European cross-border energy supply infrastructure, such as pipelines, has great importance. Whilst the potential effects of political disagreement, economic inequalities and social differences are relatively well understood, the impact of environmental change is often poorly appreciated by decision-makers. New approaches have been examined for monitoring of hazardous landslide processes, including early warning systems, and near-real-time 3D data processing and visualization. The scientific problems of environmental systems design have been discussed and approaches for their implementation have been suggested. New integrated remote sensing techniques consisting mainly of hyperspectral and radar imagery are presented together with the processing of monitoring data using GIS techniques and, in particular, dynamic visualization. Attention is also given to conceptual issues of environmental and energy security and the role of education, to help resolve environmental problems through cooperation in the development of the European energy supply infrastructure.
