Download or read book Juneau Icefield Research Project 1949 1958 written by Cal Heusser and published by Elsevier. This book was released on 2007-04-17 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Encyclopedia of Snow Ice and Glaciers written by Vijay P. Singh and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 1301 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Paleoenvironmental Record and Applications of Calcretes and Palustrine Carbonates written by Ana María Alonso-Zarza and published by Geological Society of America. This book was released on 2006-01-01 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This volume presents current understanding of the mechanisms and environments of the formation of calcretes and palustrine carbonates. Through a series of specific field examples, papers in this volume illustrate the wide variety of potential applications of these types of deposits. The papers presented here cover a wide array of ages and environmental settings of calcrete and palustrine deposition and include many interesting applications, such as the climatic and geomorphic controls on calcrete formation, possible modern analogues for palustrine carbonates, the interplay between palustrine, pedogenic, and diagenetic processes, the utility of radio-isotopic methods for dating pedogenic carbonates, applications to understanding landscape evolution, and reconstruction of diagenetic sequences. The result is a state-of-the-art book on these deposits so common in the geological record and in recent environments."--Publisher's website.

Download or read book Ecosystems of Disturbed Ground written by L.R. Walker and published by Elsevier. This book was released on 1999-12-17 with total page 881 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human population inexorably grows, its cumulative impact on the Earth's resources is hard to ignore. The ability of the Earth to support more humans is dependent on the ability of humans to manage natural resources wisely. Because disturbance alters resource levels, effective management requires understanding of the ecology of disturbance. This book is the first to take a global approach to the description of both natural and anthropogenic disturbance regimes that physically impact the ground. Natural disturbances such as erosion, volcanoes, wind, herbivory, flooding and drought plus anthropogenic disturbances such as foresty, grazing, mining, urbanization and military actions are considered. Both disturbance impacts and the biotic recovery are addressed as well as the interactions of different types of disturbance. Other chapters cover processes that are important to the understanding of disturbance of all types including soil processes, nutrient cycles, primary productivity, succession, animal behaviour and competition. Humans react to disturbances by avoiding, exacerbating, or restoring them or by passing environmental legislation. All of these issues are covered in this book. Managers need better predictive models and robust data-collections that help determine both site-specfic and generalized responses to disturbance. Multiple disturbances have a complex effect on both physical and biotic processes as they interact. This book provides a wealth of detail about the process of disturbance and recovery as well as a synthesis of the current state of knowledge about disturbance theory, with extensive documentation.

Download or read book Investigating the Holocene History of Eliot Glacier Mount Hood Oregon written by Nadia Sittara Jones and published by . This book was released on 2012 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research documents the Holocene glacial history of Mount Hood, Cascade Mountains, Oregon by analyzing a set of three lateral moraines abutting Eliot Glacier, the largest glacier on the mountain. This study seeks to: 1) establish the relative ages of these lateral moraines and 2) determine if these features represent distinct glacial advances. The hypothesis is that the lateral moraines for Eliot Glacier represent three distinct periods of glacial advance based on their position relative to the current glacier and other diagnostic indicators. Soil profiles of three positions (shoulder, backslope, and footslope) on the distal side of each lateral moraine were described in the field and samples were taken from each horizon for laboratory analyses of pH and particle size. The results of the soil analysis show that the soils developing on the moraine closest to the current glacier are poorly developed and significantly younger than the other two features. The closest moraine likely dates to the Little Ice Age (600-150 YBP) and has soils with an A/C profile and a classification of Andic Cryopsamment. The soils on the middle and furthest moraines from the glacier are similar in the profile sequence (Andic Haplocryepts). Silt bulges were noted in the mid-slope pits. The furthest moraine has deeper horizons and more color development than the middle moraine. Ash layers were found in the backslope soil profile (36-51cm deep) on the middle moraine. Additional lab testing confirms the ash layers originated from Mount Hood, but no date can be assigned. The eruptive history of Mount Hood points to the Timberline eruptive period (1,500 YBP) as a likely candidate for one of the ash deposits. This evidence suggests the middle moraine was actively forming during this period and is intermediate in age between the furthest moraine and the Little Ice Age Moraine; hence, this sequence of moraines indicates three distinct periods of glacial advance in the Neoglacial.
