Fundamentals of Glacier Dynamics, Second Edition


Book Description

Measuring, monitoring, and modeling technologies and methods changed the field of glaciology significantly in the 14 years since the publication of the first edition of Fundamentals of Glacier Dynamics. Designed to help readers achieve the basic level of understanding required to describe and model the flow and dynamics of glaciers, this second edition provides a theoretical framework for quantitatively interpreting glacier changes and for developing models of glacier flow. See What’s New in the Second Edition: Streamlined organization focusing on theory, model development, and data interpretation Introductory chapter reviews the most important mathematical tools used throughout the remainder of the book New chapter on fracture mechanics and iceberg calving Consolidated chapter covers applications of the force-budget technique using measurements of surface velocity to locate mechanical controls on glacier flow The latest developments in theory and modeling, including the addition of a discussion of exact time-dependent similarity solutions that can be used for verification of numerical models The book emphasizes developing procedures and presents derivations leading to frequently used equations step by step to allow readers to grasp the mathematical details as well as physical approximations involved without having to consult the original works. As a result, readers will have gained the understanding needed to apply similar techniques to somewhat different applications. Extensively updated with new material and focusing more on presenting the theoretical foundations of glacier flow, the book provides the tools for model validation in the form of analytical steady-state and time-evolving solutions. It provides the necessary background and theoretical foundation for developing more realistic ice-sheet models, which is essential for better integration of data and observations as well as for better model development.




The Wisconsinan Stage


Book Description




Glaciers


Book Description

"Glaciers is a volume about the role glaciers play in our daily lives (often without us knowing), the risks posed to glaciers from natural and anthropogenic activity (including climate change and industrial pollution), and policies and practices that should be employed to protect this fundamental hydrological reserve"--




Vanishing Ice


Book Description

The Arctic is thawing. In summer, cruise ships sail through the once ice-clogged Northwest Passage, lakes form on top of the Greenland Ice Sheet, and polar bears swim farther and farther in search of waning ice floes. At the opposite end of the world, floating Antarctic ice shelves are shrinking. Mountain glaciers are in retreat worldwide, unleashing flash floods and avalanches. We are on thin ice—and with melting permafrost’s potential to let loose still more greenhouse gases, these changes may be just the beginning. Vanishing Ice is a powerful depiction of the dramatic transformation of the cryosphere—the world of ice and snow—and its consequences for the human world. Delving into the major components of the cryosphere, including ice sheets, valley glaciers, permafrost, and floating ice, Vivien Gornitz gives an up-to-date explanation of key current trends in the decline of ice mass. Drawing on a long-term perspective gained by examining changes in the cryosphere and corresponding variations in sea level over millions of years, she demonstrates the link between thawing ice and sea-level rise to point to the social and economic challenges on the horizon. Gornitz highlights the widespread repercussions of ice loss, which will affect countless people far removed from frozen regions, to explain why the big meltdown matters to us all. Written for all readers and students interested in the science of our changing climate, Vanishing Ice is an accessible and lucid warning of the coming thaw.




Peatlands of Ohio and the Southern Great Lakes Region


Book Description

Exploring and appreciating the fascinating ecosystems of bogs and fens Peatlands--and specifically "bogs"--have long been a source of fascination for humans, and these amazing places are truly living relics of the Ice Age. More recently, bogs have come to be regarded as complex and fascinating wetland ecosystems. Peatlands of Ohio and the Southern Great Lakes Region focuses on the sphagnum peat bogs and rich fens of the lower Great Lakes states of Illinois, Indiana, Ohio, southern Michigan, and the glaciated northern corners of Pennsylvania. The peatlands of today are products of the Wisconsinan Glaciation, when peatland plants originating in northern latitudes migrated southward in a wide band preceding the glacial wall of ice. After thousands of years, the glacier's retreat severely diminished the sites with the very special environmental conditions needed to sustain these ecosystems. However, in a few sites, kettlehole lakes and cold alkaline hillside seeps and springs enabled remnants of peatland vegetation to survive to this day. Guy L. Denny, with accompanying photographs by Gary Meszaros, closely examines this habitat and its special environmental constraints, the geological and climatological origins, and the flora and fauna unique to the bogs and rich fens of this region. As readers will discover as they learn about places like Cranberry Bog in Michigan or Triangle Lake in Ohio, kettlehole sphagnum peat bogs and rich fens are not only essential places to protect, but they are amazing sites to explore, discover new plants, and observe the beauty and splendor of the natural world.




Thin Ice


Book Description

"One of the best books yet published on climate change . . . The best compact history of the science of global warming I have read."—Bill McKibben, The New York Review of Books The world's premier climatologist, Lonnie Thompson has been risking his career and life on the highest and most remote ice caps along the equator, in search of clues to the history of climate change. His most innovative work has taken place on these mountain glaciers, where he collects ice cores that provide detailed information about climate history, reaching back 750,000 years. To gather significant data Thompson has spent more time in the death zone—the environment above eighteen thousand feet—than any man who has ever lived. Scientist and expert climber Mark Bowen joined Thompson's crew on several expeditions; his exciting and brilliantly detailed narrative takes the reader deep inside retreating glaciers from China, across South America, and to Africa to unravel the mysteries of climate. Most important, we learn what Thompson's hard-won data reveals about global warming, the past, and the earth's probable future.







Ohio Hill Country


Book Description

In Ohio Hill Country, author Carolyn Platt describes how plant and animal life evolved to fill the many niches and micro-climates afforded by the area s weathered sandstones and shales and the ravines cut by area streams. She introduces readers to places such as the Hocking Hills and the Edge of Appalachia in Adams County, which are still home to an exotic and diverse group of flora and fauna. With engaging, readable prose complemented by maps and beautiful color photographs, Ohio Hill Country instills an understanding of and appreciation for southeastern Ohio's geology, ecology, and human history. Carolyn Platt is a retired professor of English at Cuyahoga Community College in Cleveland.
