Available in PDF, EPUB and Kindle. Book excerpt: The hydrological cycle plays a central role in geobiological and near-surface geological processes and in the energy balance of the earth. It is of crucial importance to many vital practical problems relative to man and his environment. This is especially true in arctic and subarctic regions, where knowledge of hydrologic processes is particularly limited. The introductory section of this report discusses the global hydrologic cycle and summarizes current estimates of the quantities of water involved in various portions of it. Following this, the definitions and boundaries of the arctic and subarctic are reviewed; a map showing these boundaries and annotations of a number of publications dealing with this problem are also presented. The main part of the report gives several hundred annotations of reports that directly discuss elements of the water balance in arctic and subarctic regions. These annotations are grouped by geographic area: the Northern Hemisphere, Europe, the U.S.S.R., Alaska, Canada, and Greenland and Iceland. For each area, annotations are presented according to water-balance elements: precipitation, evapotranspiration, runoff, streamflow, groundwater contributions to runoff, and changes in glacial storage.

Download or read book Groundwater Dynamics in Degrading Discontinuous Permafrost written by Michelle Lee Barnes and published by . This book was released on 2014 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: In regions impacted by permafrost, discontinuities are areas of possible connection between the supra- and sub-permafrost portions of an aquifer. Permafrost discontinuities influence the transport of contaminants in an aquifer, necessitating delineation of these discontinuities and their influence on groundwater flow. Means of identifying the locations of permafrost discontinuities have previously been limited to geophysical methods and the evaluation of well logs. In this study we use groundwater elevation trends and environmental tracers (e.g., stable isotopes and temperature) to evaluate the dynamics in a sulfolane-contaminated aquifer located in a region of discontinuous permafrost in the Interior of Alaska. Using tracers to identify areas of discontinuities in the permafrost should help us locate thawed through-taliks and may also improve our understanding of the interaction between the supra- and sub-permafrost groundwater in discontinuous permafrost. With this approach we identified at least three discontinuities within the study area. The locations of these discontinuities coincide with transport of the contaminant found in this aquifer. The primary source of recharge for this aquifer is the Tanana River, a major tributary to the Yukon River. The source of water for the Tanana River is glacial melt in the summer and groundwater during the winter. Through the isotopic composition of the supra-permafrost groundwater we show the occurrence of additional recharge to the supra-permafrost groundwater from sub-permafrost groundwater and precipitation. Understanding these dynamics is paramount to characterizing the contaminant transport in permafrost impacted aquifers.

Download or read book The Periglacial Environment written by Hugh M. French and published by John Wiley & Sons. This book was released on 2017-10-27 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2019 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arctic landscapes are more susceptible to stronger and earlier impacts from climate change than are the mid-latitudes. The potential for the vast amount of carbon that has been stored in permafrost soils (1400-1850 Pg, Grosse et. al, 2011) for thousands of years to be mobilized due permafrost degradation and thermokarst development in response to climate change is poorly understood and of global importance. With the prevalence of thermokarst lakes in arctic regions, thaw beneath these lakes in response to a changing climate will be an important pathway for carbon and methane release into the atmosphere. Using a lake ice regime classification based on spaceborne synthetic aperture radar over a 25-year time period, we can begin to decipher the trends in bedfast ice extent in response to differing environmental parameters and ambient conditions. Trends in the distribution of bedfast ice extent for lakes in the 0-60% bedfast ice interval emerged by applying a robust probability density function statistical methodological technique. Simple linear regression analysis revealed statistically significant slopes and good model performance in the vulnerable sub-population of lakes that are floating ice across the Inner and Outer Coastal Plains of the North Slope. Using transient electromagnetic soundings on 33 lakes, we can characterize the electrical resistivity profiles of lakes of different ice regimes. In general, bedfast ice regime lakes had the most resistive profile corresponding to little to no permafrost thaw and floating ice lakes had the least resistive profiles corresponding to associated permafrost thaw beneath them. Transitional ice lake profiles were more closely related to floating ice lake profiles than bedfast ice. In a case study of eleven transitional ice lakes in the Barrow region, we find there exists a linear relationship between the proportion of time a lake has been under floating ice conditions and the depth of the talik. Combining lake initiation age, thermal modeling using available ground material properties, and geophysical investigations we are able to independently determine talik thickness across transects of a lake with different lake shore expansion rates. Both thermal modeling and geophysical methods showed deeper talik development than previous modeling studies on the Alaskan coastal plain. The products of this work include past, present, and projected distribution of bedfast ice regime lakes in the study areas across the Alaskan North Slope and permafrost thaw associated with the change in ice regime. These results, when coupled to the permafrost-water-climate system, greatly increase our understanding of how lake rich arctic regions are responding in response to changing ambient weather conditions. This is of particular importance for expanses of lowland Alaska, Canada, and Siberia where arctic amplification has been severe and expected to continue.
Download or read book Geocryology written by Stuart A. Harris and published by CRC Press. This book was released on 2017-09-28 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature.
