Book Description
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.

Book Description
The Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field. The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)

Book Description
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.

Book Description
Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundreds of research papers and special issues of journals dedicated to the topic. The explosion of primary literature devoted to GPR technology, theory and applications, has lead to a strong demand for an up-to-date synthesis and overview of this rapidly developing field. Because there are specifics in the utilization of GPR for different applications, a review of the current state of development of the applications along with the fundamental theory is required. This book will provide sufficient detail to allow both practitioners and newcomers to the area of GPR to use it as a handbook and primary research reference. *Review of GPR theory and applications by leaders in the field*Up-to-date information and references*Effective handbook and primary research reference for both experienced practitioners and newcomers

Book Description
Examination of the sedimentary record in areas occupied by fast flowing outlet glaciers and ice streams is critical for understanding ice sheet dynamics on millennial timescales. We use high-resolution seismic data together with log data and foraminiferal-based radiocarbon and isotope data from Integrated Ocean Drilling Program (IODP) Expedition 341 cores to examine the evolution of the Cordilleran Ice Sheet (CIS) in southeast Alaska. Evidence for at least seven advances of the Bering Glacier to the shelf break since the end of Middle Pleistocene Transition (MPT) are interpreted from the seismic data. Seismic data demonstrate two distinctive patterns of slope sedimentation, which are: (1) dominated by sediments bypassing a steep paleo-slope or (2) dominated by glacigenic debris flows (GDFs) that form a trough mouth fan (TMF) on a lower slope. Integration of seismic, well, and age data suggests that the TMF was formed as a result of three advances to the shelf break since ca. 140 ka, implying extreme (average > 4m/ka) rates of sediment delivery. Extraordinarily high sediment flux played a key role in the development of the margin architecture resulting from a temperate, highly aggressive Bering Glacial System and abundant source of erodible bedrock onshore (St. Elias orogeny). We use the first high-resolution seismic data acquired on the Sabrina Coast, East Antarctica, together with core data, to examine major transitions in glacial regime of East Antarctic Ice Sheet. Three large-scale megasequences represent changes in the dominant pattern of sedimentation: Megasequence I shows signs of Eocene fluvial and possibly glacio-fluvial sedimentation; Megasequence II provides evidence of Oligocene-Miocene polythermal glacial sedimentation with significant amount of meltwater; Megasequence III overlies the regional erosional surface that marks major Miocene ice sheet expansion and transition into polar (cold-based) ice sheet glacial regime with no significant evidence of subglacial meltwater preserved. Megasequence II exhibits preserved record of EAIS evolution starting from its first expansion. Seismic stratigraphic analysis suggests a dynamic glacial late Paleogene-early Neogene evolution including expansions of the EAIS across the shelf at least eight times, which is marked by erosional surfaces and chaotic acoustic character of overlying strata. We report on finding the first conclusive seismic evidence of deep, extensive tunnel valley systems incised into sedimentary substrate from Antarctic continental margins. The Sabrina Coast tunnel valley system was presumably formed during Oligocene as a result of the second major EAIS shelf expansion. Shallower erosion events observed in the upper part of Megasequence II suggest more extensive glaciations in the Oligocene compared to the Miocene.
