Book Description
The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available for download at: http://booksite.elsevier.com/9780444534477/ Completely updated detailed coverage of worldwide Quaternary glaciations Information in digital, uniformly prepared maps which can be used in a GIS such as ArcView or ArcGis Step-by-step guideline how to open and use ArcGis files Possibility to convert the shapefiles into GoogleEarth kmz-files Availability of chronological controls

Book Description
This book represents the archeological evidence for the first 5,500 years of prehistory in British Columbia, from about 10,500 to 5,000 years ago. As this period is poorly known, even to specialists, Early Human Occupation in British Columbia is a vital contribution to current knowledge about an enigmatic time in a critically important area of western North America.

Book Description
The Juneau Icefield Research Project (JIRP) was formed to find a prototype area to study Alaska's coastal glaciers and trends in climatic change. For the past 57 years JIRP has conducted a systematic study of key receding and advancing glaciers, including Lemon Creek and Taku Glaciers. From this study, a model has been developed to study the mass balance of these glaciers and their relation to general atmospheric circulation. Taku's mass balance was expected to provide a meaningful assessment of flakier climate relations and environmental trends, specifically the increase in atmospheric trace element pollution and global warming.Juneau Icefield Research Project (1949-1958) is represented by 15 chapters, organized in four parts: Background of the Project, Early Years of the Project (1949-1952, Later Years of the Project (1953-1958), and Summation and Epilogue. After describing the Project's background, Chapters 3 through 12 cover year-by-year activities, personnel, logistics, and research of the Taku and Lemon Creek Glaciers. These chapters included day-to-day journal entries that represent a record of the informal itineraries covering the course of the study. Chapters 13 and 14 summarize glaciological findings on Taku Glacier and the status of hydrological budgets on Lemon Creek Glacier through the International Geophysical year (1957-19658). The final chapter of the text is an overview of paleoecological work by the Project in North Pacific America brought into the context of modern research with the recognition of glacier-climate cycles.* Documents the study Juneau Icefield Research Project on a year-by-year account covering activities, personnel, logistics and research * Discusses the model developed from the JIRP and explains its importance in predicting future climate changes* Presents the information with day-to-day journal entries, making the text attractive and easy to read

Book Description
Reports preliminary results from scientific cruises in the central & northern Strait of Georgia conducted to study the regional glacial & sea-level history of the area. The cruises collected a regional network of geophysical sub-bottom profiles and 54 sediment cores. The preliminary results describe six Quaternary sediment facies identified from the acoustic stratigraphy, including pre-glacial sediments, glacial till, ice-proximal sediments, glaciomarine mud, and Holocene deposits. Preliminary data are presented to support a previous interpretation of changes in sea level.

Book Description
The end of the Pleistocene era brought dramatic environmental changes to small bands of humans living in North America: changes that affected subsistence, mobility, demography, technology, and social relations. The transition they made from Paleoindian (Pleistocene) to Archaic (Early Holocene) societies represents the first major cultural shift that took place solely in the Americas. This event—which manifested in ways and at times much more varied than often supposed—set the stage for the unique developments of behavioral complexity that distinguish later Native American prehistoric societies. Using localized studies and broad regional syntheses, the contributors to this volume demonstrate the diversity of adaptations to the dynamic and changing environmental and cultural landscapes that occurred between the Pleistocene and early portion of the Holocene. The authors' research areas range from Northern Mexico to Alaska and across the continent to the American Northeast, synthesizing the copious available evidence from well-known and recent excavations.With its methodologically and geographically diverse approach, From the Pleistocene to the Holocene: Human Organization and Cultural Transformations in Prehistoric North America provides an overview of the present state of knowledge regarding this crucial transformative period in Native North America. It offers a large-scale synthesis of human adaptation, reflects the range of ideas and concepts in current archaeological theoretical approaches, and acts as a springboard for future explanations and models of prehistoric change.

Book Description
The world's continental shelves are the sites of vast resources of food, energy and minerals, the exploitation of which is continuously increasing. Fluctuating global sea levels throughout the Quaternary period produced multiple transgressive and regressive cycles that profoundly affected and shaped these shelves. The complex interactions among climate, sea level, tectonics, oceanography and sediment input have formed distinctive sediment packages on each shelf and provide a guide to the interpretation of older shelf sequences throughout the geological record. This Memoir compiles studies on 23 selected shelves from all the continents, focusing on their evolution and examining the patterns of sedimentation during the past approximately 125 000 years. In addition to providing basic background information for each area, the chapters consider specific aspects of continental shelf research, from seismic stratigraphy to geomorphology, from palaeoceanography to palaeo sea-level reconstruction and from palaeontology to geochemistry.

Book Description
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.
