A fascinating and informative exploration of periglacial processes, past and present, and their role in landscape evolution Periglacial Geomorphology presents a comprehensive introduction to the processes that operate in present periglacial environments and discusses the inferences that can be drawn about former periglacial environments from those processes. Organized into six parts, the book opens with the historical and scientific context of periglacial geomorphology and the nature of periglacial environments. Following chapters provide systematic coverage of the full range of topics germane to a thorough understanding of periglacial geomorphology, including: The physics of ground freezing and thawing, characteristics of permafrost, and the nature and origin of underground ice Characteristics, formation and significance of landforms, sediments, and structures associated with permafrost, permafrost degradation, and seasonal ground freezing and thawing Rock weathering in periglacial environments, periglacial processes operating on hillslopes, and the characteristic landforms produced by rock breakdown and slope processes in cold environments The operation of fluvial, aeolian and coastal processes in cold environments, and the resulting distinctive landforms and sediments The use of relict periglacial features to reconstruct past cold environments in midlatitude regions and the responses of periglacial environments to recent and predicted climate change Periglacial Geomorphology is an important resource for undergraduate and graduate students studying geomorphology or Quaternary science within the context of geography and geology degree programs. It will be of use to all scientists whose research involves an understanding of cold environments, whether from a geographical, geological, ecological, climatological, pedological, hydrological, or engineering perspective.

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.

The study of glaciers is important not only for explaining how landscapes are created, but also for understanding global issues such as climate change and sea-level rise. This book examines the characteristics of glaciers, explores how they shape the landscape, and explains their role in the unfolding drama of global environmental change. It also considers the impact of glaciers on human activity, and the potential impact of humans on the future growth or melting of the world's ice. The aim of the book is to provide a quick, straightforward introduction to glaciers and glacial landscapes. It is intended for people who have very little background knowledge in the subject, and is pitched very much at an introductory level. Given the importance of glaciers in the global environmental system it is surprising that they come and go in the teaching syllabus. For a few years, lots of students are studying glaciers at school, then for a few years nobody is doing glaciers and everybody is studying rivers instead. Teachers who perhaps did not study glaciers at university suddenly find that a curriculum change at school leaves them having to teach glaciers to their own students. Students at university find that they have to deal with glaciers at degree level even though they never studied them at school. University lecturers find that the students just enrolled on what was intended as a degree-level glaciers module have no background at all in the subject. And members of the general public who just want to find out a little bit about glaciers discover that the only books available are either coffee-table books with no real information or advanced texts intended for people who already have some expertise. This little book throws itself into that picture with the aim of helping all those readers!

Dynamic Mars: Recent and Current Landscape Evolution of the Red Planet presents the latest observations, interpretations, and explanations of geological change at the surface or near-surface of this terrestrial body. These changes raise questions about a decades-old paradigm, formed largely in the aftermath of very coarse Mariner-mission imagery in the 1960s, suggesting that much of the interesting geological activity on Mars occurred deep in its past, eons ago. The book includes discussions of (1) Mars’ ever-changing atmosphere and the impact of this on the planet’s surface and near-surface; (2) the possible involvement of water in relatively new, if not contemporary, gully-like flows and slope streaks (i.e. recurring slope lineae); and (3) the identification of a broad suite of agents and processes (i.e. glacial, periglacial, aeolian, meteorological, volcanic, and meteoric) that are actively revising surface and near-surface landscapes, landforms, and features on a local, regional, and hemispheric scale. Highly illustrated and punctuated by data from the most recent Mars missions, Dynamic Mars is a valuable resource for all levels of research in the geological history of Mars, as well as of the three other terrestrial planets. Utilizes observational and model-based data as well as geological context to frame the understanding of Mars’ dynamic surface and near-surface Presents a broad spectrum of highly regarded experts and themes to discuss and evaluate the geological history of late and current Mars Includes extensive and detailed imagery to clearly illustrate these themes, discussions, and evaluations

This undergraduate textbook provides a current and comprehensive survey of the sediments and forms generated within Pleistocene and pre-Pleistocene glacial environments. Techniques and methods used in the examination of these sediments and forms are extensively reviewed. This is the most comprehensive and wide-ranging book ever prepared on this topic, and will form the basis for future work in the area. In studying past glacial environments, links are made between understanding modern glaciodynamics, ice physics, and the processes of erosion, transport and deposition of glacial sediments and the generation of various glacial landforms. Past Glacial Environments presents physical geography, earth and environmental science students with an extensive review of the latest research on past glacial environments. The text encompasses Pleistocene subglacial, supraglacial and proglacial sediments and environments, pre-Pleistocene global glacial conditions and sediments, as well as past glacioaeolian, glaciolacustrine, and glaciomarine sediments. Subsequent chapters focus on stratigraphy, lithofacies associations, paleosols, glacio-eustasy and isostasy, micromorphology, SEM, drift prospecting and placer mining.

This book, originally published in 1980, provides a comprehensive overview of frost-action and mass-wasting processes and their effects, present and past. As warming of permafrost is becoming an increasingly important component of global climate change research, this text is also of increasing relevance. Geocryology is included in the title to emphasize the pervasive influence of ice and its phase changes in these processes. This book is neither a formal text nor a reference manual but something of both and a guide to the enormous literature. The text is illustrated with over 200 photographs and diagrams. The following topics are covered: Environmental factors, frozen ground, general frost-action processes, some periglacial forms, mass-wasting processes and forms, nivation, slopewash, fluvial action, lacrustine and marine action, wind action, thermokarst, environmental overview and environmental reconstructions. L. Washburn was the first executive director of the Arctic Institute of North America. He dedicated his life to fieldwork and the intensive study of the Arctic and Polar Regions in general, focusing on glacial and periglacial environments and Quaternary history of the earth. Dr. Washburn was Professor Emeritus in the department of Geological Sciences and the Quaternary Research Center at the University of Washington, and former Director of its Quaternary Research Center. He was deeply involved in the establishment of the journal Arctic and was founder and former Editor of Quaternary Research.

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.

Studies in the Scottish Lateglacial Environment presents information on environmental reconstructions and dramatic changes, as well as the important implications of studies of the Lateglacial environment for Quaternary studies and modern climatic variations. Composed of 10 chapters, this book begins with a review of the Late Devensian glaciation in north-east Scotland. Then, detailed evidence concerning Lateglacial sea-level changes in the Earn-Tay area and their relationship to deglaciation is presented. Subsequent chapters explore the validity of the Oban-Ford Moraine, the only pre-Loch Lomond Readvance moraine remaining virtually unchallenged in the literature; reconstruction of Lateglacial and early Flandrian environments in south-west Scotland; and the fauna in marine sediments at Lochgilphead. Other chapters describe results of pollen-stratigraphic investigations at six Lateglacial sites in the southern and eastern Grampian Highlands; analyses of biological and chemical variables from sediment profiles from lochs in northern Scotland; and radiocarbon dates that are related to pollen profiles from the Scottish Highlands and the Isle of Skye. This book will be of value to students of Quaternary, as this text provides an integrated survey of available information in this field.

This book discusses the political and economic history and geography of Georgia, the problems it has faced, and how it has overcome and is still overcoming them. In most countries, at the end of the 20th century the successful resolution of social-economic, political, demographic and ecological problems was largely dependent on effectively protecting the population and economic assets from natural disasters and on ensuring conditions for their sustainable development. These problems are most acute in mountainous regions like Georgia, where the unplanned development of natural ecosystems has had drastic consequences. It is therefore necessary to understand not only the probability of changing conditions (natural as well as political and demographic), but also the probability of the resulting economic losses. The book is divided into four sections; historical and political geography, geological processes, ecological processes and developmental geography. In the historical and political geography section the authors present a detailed discussion on ancient history, historical and political geography, ethnic groups and religions, demographics and socio-cultural geography. The geological processes section contains information on geology, geodynamical processes, glacial and periglacial processes. The ecological processes section examines a variety of landscapes and ecosystems, aspects of deforestation, reforestation and desertification along with anthropogenic impacts on the environment. The developmental geography section looks at different economies, natural resources, sustainable development and climate change.

The volume highlights developments in our understanding of the palaeogeographical, palaeobiological, palaeoclimatic and cryospheric evolution of Antarctica. It focuses on the sedimentary record from the Devonian to the Quaternary Period. It features tectonic evolution and stratigraphy, as well as processes taking place adjacent to, beneath and beyond the ice-sheet margin, including the continental shelf. The contributions in this volume include several invited review papers, as well as original research papers arising from the International Symposium on Antarctic Earth Sciences in Edinburgh, in July 2011. These papers demonstrate a remarkable diversity of Earth science interests in the Antarctic. Following international trends, there is particular emphasis on the Cenozoic Era, reflecting the increasing emphasis on the documentation and understanding of the past record of ice-sheet fluctuations. Furthermore, Antarctic Earth history is providing us with important information about potential future trends, as the impact of global warming is increasingly felt on the continent and its ocean.
