It is shown that the temperature gradient normal to the bed is an important parameter in determining whether sliding can or cannot occur in a glacier whose bottom surface is at the melting point. Only if a large temperature gradient exists will sliding be prevented. Since the temperature gradient of a glacier whose bottom surface is at the melting point is expected to be small, it is concluded that sliding usually will occur in such a glacier even if obstacles in the bed may protrude into cold ice.

The book unifies classical continuum mechanics and turbulence modeling, i.e. the same fundamental concepts are used to derive model equations for material behaviour and turbulence closure and complements these with methods of dimensional analysis. The intention is to equip the reader with the ability to understand the complex nonlinear modeling in material behaviour and turbulence closure as well as to derive or invent his own models. Examples are mostly taken from environmental physics and geophysics.

This proceedings volume is the fifth in our continuing publication series that result from the annual geomorphology symposiums conducted in the Department of Geological Sciences, State University of New York at Binghamton. The First proceedings Environmental Geomorphology spoke to an emerging Geld that is becoming ever more popular and necessary in today's complex world. The Second proceedings, Quantitative Geomorphology, again cross-cut many of the geomorphic subdisciplines and united them with one of the most important methodologies of the science. The Third and Fourth proceedings, Coastal Geomorphology and Fluvial Geomorphology, zeroed in on analysis of the special processes that comprise the fundamental building blocks of geomorphic research. The present volume continues this trend ht showing how the dynamic processes associated with glaciation transform the landscape. There are many different avenues for expression of scientific ideas, but the knowledge and publication explosion creates hardships for those who attempt to keep in tune with their specialties. It is not our purpose to add an unnecessary burden to this verbage increase. Instead we feel there comes a time when reassessment of the vital fabric of geomorphology is necessary and where geomorphologists can gather as a group to share their newest ideas. The more than 300 participants who have been attending these yearly symposia attest that this type of event helps fi11 a communications gap.

Glacier-Permafrost Interactions A systematic exploration of the interactions between glaciers and permafrost In Glacier-Permafrost Interactions, experienced glaciologist Richard I. Waller delivers a comprehensive discussion of the interactions between glaciers and permafrost. The book is highly relevant to contemporary debates regarding ongoing recession of glaciers and the degradation of permafrost in the face of global warming. By integrating modern-era observations with findings from Quaternary science, this book demonstrates how glaciers and permafrost can interact and behave as an integrated system. This summary of the current thinking and emerging research on glacier-permafrost interaction also provides: Comprehensive discussions of permafrost in modern and ancient glacial environments A focused review of the distinctive characteristics of glaciers found in permafrost environments An integrated overview of the nature and impacts of glacier-permafrost interactions on the hydrology and dynamic behaviour of glaciers and their landscape expression A survey of current research efforts and future directions in the field Lying at the boundary between a research monograph and an advanced textbook, Glacier-Permafrost Interactions contributes to the future development of this rapidly evolving field by incorporating new approaches and ideas while still offering a summary of the current state of knowledge. It is perfect for advanced undergraduate students, postgraduate students, researchers, and professionals with an interest in polar and alpine environments.

Our realisation of how profoundly glaciers and ice sheets respond to climate change and impact sea level and the environment has propelled their study to the forefront of Earth system science. Aspects of this multidisciplinary endeavour now constitute major areas of research. This book is named after the international summer school held annually in the beautiful alpine village of Karthaus, Northern Italy, and consists of twenty chapters based on lectures from the school. They cover theory, methods, and observations, and introduce readers to essential glaciological topics such as ice-flow dynamics, polar meteorology, mass balance, ice-core analysis, paleoclimatology, remote sensing and geophysical methods, glacial isostatic adjustment, modern and past glacial fluctuations, and ice sheet reconstruction. The chapters were written by thirty-four contributing authors who are leading international authorities in their fields. The book can be used as a graduate-level textbook for a university course, and as a valuable reference guide for practising glaciologists and climate scientists.
