Download or read book Melt Water Retention Processes in Snow and Firn on Ice Sheets and Glaciers Observations and Modeling written by W. Tad Pfeffer and published by Frontiers Media SA. This book was released on 2018-11-08 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Melt takes place where the surface of glaciers or ice sheets interacts with the atmosphere. While the processes governing surface melt are fairly well understood, the pathways of the meltwater, from its origin to the moment it leaves a glacier system, remain enigmatic. It is not even guaranteed that meltwater leaves a glacier or ice sheet. On Greenland, for example, only slightly more than 50% of the meltwater runs off. The remainder mostly refreezes within the so-called firn cover of the ice sheet. This eBook contains 11 studies which tackle the challenge of understanding meltwater retention in snow and firn from various angles. The studies focus both on mountain glaciers and on the Greenland ice sheet and address challenges such as measuring firn properties, quantifying their influence on meltwater retention, modelling firn processes and meltwater refreezing as well as unravelling the mechanisms within the recently discovered Greenland firn aquifers.

Tomorrow's most successful brands are already embracing Outside Insight, benefitting from an information advantage while their competition is left behind. Drawing on practical examples of transformative, data-led decisions made by brands like Apple, Facebook, Barack Obama and many more, in Outside Insight, Meltwater CEO Jorn Lyseggen illustrates the future of corporate decision-making and offers a detailed plan for business leaders to implement Outside Insight thinking into their company mindset and processes.

Download or read book Meltwater written by Michael Ridpath and published by Atlantic Books. This book was released on 2014-06-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third book in the Fire & Ice series featuring Icelandic detective Magnus Jonson FreeFlow, a group of internet activists committed to the freedom of information, have video evidence of a military atrocity in the Middle East and have chosen Iceland as their HQ while they prepare to unleash their greatest coup on the world's media. On the glacial rim of erupting volcano Eyjafjallaj&ökull, minutes after they christen their endeavor Operation Meltwater, one of them is murdered. The list of people Freeflow has antagonized is long—the Chinese government, Israeli military, a German Bank, Italian politicians, even U.S. college fraternities. Magnus Jonson has a long list of suspects but he's getting precious little help from FreeFlow—for an organization dedicated to the transparency of information, they're a secretive bunch. But they are not the only ones with secrets. Asta, a newly qualified priest, has contacted FreeFlow with information about a scandal in the church. Her involvement with FreeFlow will cost her dearly. And with the return of Magnus's brother Ollie to Iceland, the feud that has haunted their family for three generations is about to reignite.

Download or read book Effects of Past Global Change on Life written by Panel on Effects of Past Global Change on Life and published by National Academies Press. This book was released on 1995-01-15 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: What can we expect as global change progresses? Will there be thresholds that trigger sudden shifts in environmental conditions--or that cause catastrophic destruction of life? Effects of Past Global Change on Life explores what earth scientists are learning about the impact of large-scale environmental changes on ancient life--and how these findings may help us resolve today's environmental controversies. Leading authorities discuss historical climate trends and what can be learned from the mass extinctions and other critical periods about the rise and fall of plant and animal species in response to global change. The volume develops a picture of how environmental change has closed some evolutionary doors while opening others--including profound effects on the early members of the human family. An expert panel offers specific recommendations on expanding research and improving investigative tools--and targets historical periods and geological and biological patterns with the most promise of shedding light on future developments. This readable and informative book will be of special interest to professionals in the earth sciences and the environmental community as well as concerned policymakers.

Download or read book Glaciogenic Reservoirs and Hydrocarbon Systems written by M. Huuse and published by Geological Society of London. This book was released on 2012 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Glaciogenic reservoirs and hydrocarbon systems occur intermittently throughout the stratigraphic record, with particular prominence in Neoproterozoic, Late Ordovician, Permo-Carboniferous and Late Cenozoic strata. Recent interest in glaciogenic successions has been fuelled by hydrocarbon discoveries in ancient glaciogenic reservoirs in North Africa, the Middle East, Australia and South America. Glaciogenic deposits of Pleistocene age are noteworthy for their content of groundwater onshore and potentially prospective and/or hazardous gas accumulations offshore. The abundant imprints of Pleistocene glaciations in both hemispheres can be used to reconstruct complex histories of repeated ice cover and retreat, and glacier-bed interactions, thus informing our view on the dynamics of older ice caps and predictions of future glaciations. This volume aims to provide a better understanding of glaciogenic processes, their stratigraphic record and reservoir characteristics of glaciogenic deposits. The book comprises 3 overview papers and 16 original case studies of Neoproterozoic to Pleistocene successions on 6 continents and will be of interest to sedimentologists, glaciologists, geophysicists, hydrologists and petroleum geologists alike."-- P. 4 of cover.

Download or read book Seasonal Snowpacks written by Trevor D. Davies and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seasonal Snowpacks examines the processes which control the chemistry of seasonal snowcover and provides detailed information on the biogeographical distribution of snow (e.g. urban, alpine snowpacks), snow composition (e.g. micropollutants, stable isotopes) or the physical and biological processes which influence the chemical changes in snow (e.g. wind, microbiological activity). The fluxes of chemicals at the snow-atmosphere and snow-soil interfaces are examined, as are processes which modify composition within the snowcover. It is the first book in which the reader will find a comprehensive overview of the theoretical concepts, latest measurement techniques, process-oriented research methods, and models of studies in snow chemistry. The linkages between snow chemistry, atmospheric chemistry and hydrology will make this book of use to both research workers and students in the physical and biological sciences and to natural resource management personnel.

Download or read book The New Border Wars written by Klaus Dodds and published by Diversion Books. This book was released on 2021-09-28 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: An enlightening look at contemporary border tensions—from the Gaza Strip to the space race—by one of the world’s leading experts in geopolitics. Border expert Klaus Dodds journeys into the geopolitical clashes of tomorrow in an eye-opening tour of border walls both literal and figurative. In the Himalayas, the Mediterranean, and elsewhere, the tension inherent to trying to divide the world into separate parcels has not gone away. And with climate change shifting our natural borders, from mountains to glaciers to rivers, the question of how we live in a world that’s becoming warmer and wetter and growing in population looms large. With wide-ranging insight and provocative analysis, Dodds shows why we are more likely to see more walls, barriers, and securitization in our daily lives. The New Border Wars examines just what borders truly mean in the modern world: How are they built; what do they signify for citizens and governments; and how do they help us understand our political past and, most importantly, our diplomatic future?

Download or read book Canada s Cold Environments written by Hugh M. French and published by McGill-Queen's Press - MQUP. This book was released on 1993 with total page 772 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Antarctic Ecosystems written by Alex D. Rogers and published by John Wiley & Sons. This book was released on 2012-02-28 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its discovery Antarctica has held a deep fascination for biologists. Extreme environmental conditions, seasonality and isolation have lead to some of the most striking examples of natural selection and adaptation on Earth. Paradoxically, some of these adaptations may pose constraints on the ability of the Antarctic biota to respond to climate change. Parts of Antarctica are showing some of the largest changes in temperature and other environmental conditions in the world. In this volume, published in association with the Royal Society, leading polar scientists present a synthesis of the latest research on the biological systems in Antarctica, covering organisms from microbes to vertebrate higher predators. This book comes at a time when new technologies and approaches allow the implications of climate change and other direct human impacts on Antarctica to be viewed at a range of scales; across entire regions, whole ecosystems and down to the level of species and variation within their genomes. Chapters address both Antarctic terrestrial and marine ecosystems, and the scientific and management challenges of the future are explored.
