An international team of over 150 experts provide up-to-date satellite imaging and quantitative analysis of the state and dynamics of the glaciers around the world, and they provide an in-depth review of analysis methodologies. Includes an e-published supplement. Global Land Ice Measurements from Space - Satellite Multispectral Imaging of Glaciers (GLIMS book for short) is the leading state-of-the-art technical and interpretive presentation of satellite image data and analysis of the changing state of the world's glaciers. The book is the most definitive, comprehensive product of a global glacier remote sensing consortium, Global Land Ice Measurements from Space (GLIMS, http://www.glims.org). With 33 chapters and a companion e-supplement, the world's foremost experts in satellite image analysis of glaciers analyze the current state and recent and possible future changes of glaciers across the globe and interpret these findings for policy planners. Climate change is with us for some time to come, and its impacts are being felt by the world's population. The GLIMS Book, to be released about the same time as the IPCC's 5th Assessment report on global climate warming, buttresses and adds rich details and authority to the global change community's understanding of climate change impacts on the cryosphere. This will be a definitive and technically complete reference for experts and students examining the responses of glaciers to climate change. World experts demonstrate that glaciers are changing in response to the ongoing climatic upheaval in addition to other factors that pertain to the circumstances of individual glaciers. The global mosaic of glacier changes is documented by quantitative analyses and are placed into a perspective of causative factors. Starting with a Foreword, Preface, and Introduction, the GLIMS book gives the rationale for and history of glacier monitoring and satellite data analysis. It includes a comprehensive set of six "how-to" methodology chapters, twenty-five chapters detailing regional glacier state and dynamical changes, and an in-depth summary and interpretation chapter placing the observed glacier changes into a global context of the coupled atmosphere-land-ocean system. An accompanying e-supplement will include oversize imagery and other other highly visual renderings of scientific data.

"This volume contributes to the current discussion of the role of natural and anthropogenic driving forces for coastal processes and their socioeconomic consequences. Special attention is paid to computerized tools that allow us--based on reconstruction of paleodevelopments--to predict the interference of processes on different time scales. On the one hand, the book provides an overview of the current model developments in describing vertical crustal movement, climate change forcing sea-level variations, the genesis of the basin fill along continental margins, and the interference of these processes in coastal development. On the other hand, it describes coastal development in key areas for different climate zones and geological settings. Coastline Changes is addressed to students and professionals in the geosciences, archaeology, social sciences, economy, and computer sciences. It will foster interdisciplinary discussion for the purpose of developing integrated concepts for sustainable development of the coastal zones."--Publisher's website.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 180. This volume addresses the rapid decline of Arctic sea ice, placing recent sea ice decline in the context of past observations, climate model simulations and projections, and simple models of the climate sensitivity of sea ice. Highlights of the work presented here include An appraisal of the role played by wind forcing in driving the decline; A reconstruction of Arctic sea ice conditions prior to human observations, based on proxy data from sediments; A modeling approach for assessing the impact of sea ice decline on polar bears, used as input to the U.S. Fish and Wildlife Service's decision to list the polar bear as a threatened species under the Endangered Species Act; Contrasting studies on the existence of a "tipping point," beyond which Arctic sea ice decline will become (or has already become) irreversible, including an examination of the role of the small ice cap instability in global warming simulations; A significant summertime atmospheric response to sea ice reduction in an atmospheric general circulation model, suggesting a positive feedback and the potential for short-term climate prediction. The book will be of interest to researchers attempting to understand the recent behavior of Arctic sea ice, model projections of future sea ice loss, and the consequences of sea ice loss for the natural and human systems of the Arctic.

This thesis focuses on the dynamics of autonomous Boolean networks, on the basis of Boolean logic functions in continuous time without external clocking. These networks are realized with integrated circuits on an electronic chip as a field programmable gate array (FPGA) with roughly 100,000 logic gates, offering an extremely flexible model system. It allows fast and cheap design cycles and large networks with arbitrary topologies and coupling delays. The author presents pioneering results on theoretical modeling, experimental realization, and selected applications. In this regard, three classes of novel dynamic behavior are investigated: (i) Chaotic Boolean networks are proposed as high-speed physical random number generators with high bit rates. (ii) Networks of periodic Boolean oscillators are home to long-living transient chimera states, i.e., novel patterns of coexisting domains of spatially coherent (synchronized) and incoherent (desynchronized) dynamics. (iii) Excitable networks exhibit cluster synchronization and can be used as fast artificial Boolean neurons whose spiking patterns can be controlled. This work presents the first experimental platform for large complex networks, which will facilitate exciting future developments.

The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. The volume addresses the following major topics: - Research results in observing aspects of the Arctic climate system and its processes across a range of time and space scales - Representation of cryospheric, atmospheric, and oceanic processes in models, including simulation of their interaction with coupled models - Our understanding of the role of the Arctic in the global climate system, its response to large-scale climate variations, and the processes involved.

The Arctic is an increasingly important region faced with major challenges caused not only by the effects of climate change, but also by a growing interest in its living and non-living resources, its attraction as a new destination for tourism, and as a route for navigation. It is not only the eight Arctic States that have paid an increased level of attention to the region; several non-Arctic actors from Asia and Europe also seek to gain more influence in the High North. At the same time, the evolving law and policy architecture for the Arctic region has recently played a more prominent role in the political and academic debate. Unlike Antarctica, where the coherent Antarctic Treaty System governs international cooperation, the legal regime of Arctic affairs is based on public international law, domestic law, and 'soft law'. These three pillars intersect and interact making Arctic governance multi-faceted and highly complex. This book provides an analytical introduction, a chronology of legally relevant events, and a selection of essential materials covering a wide range of issues-eg delineation and delimitation of maritime boundaries, environmental protection, indigenous peoples' rights, shipping, and fisheries. Included are multilateral and bilateral treaties, UN documents, official statements, informal instruments, domestic laws, and diplomatic correspondence.

This book examines emerging forms of governance in the Arctic region, exploring how different types of state and non-state actors promote and support rules and standards. The authors argue that confining our understandings of Arctic governance to Arctic states and a focus on the Arctic Council as the primary site of circumpolar governance provides an incomplete picture. Instead, they embrace the complexity of governance in the Arctic by systematically analyzing and comparing the position, interventions, and influence of different actor groups seeking to shape Arctic political and economic outcomes in multiple sites of Arctic politics, both formal and informal.This book assesses the potential that sub-national governments, corporations, civil society organizations, Indigenous peoples and non-Arctic states possess to develop norms and standards to ensure a stable, rule-based Arctic region. It will be of interest to all scholars and students working in the fields of Arctic Sovereignty, Security Studies, Global Governance and International Political Economy.

The twenty-two papers contained in this volume have been selected from the Proceedings of the 2nd COSPAR Colloquium. The exploration of planet Mars will be the focal point of the planetary missions in the coming years, so the investigation of the surface and the upper layers of the soil is of primary importance. The major space agencies are actively working to understand the environmental and technical requirements of the planned missions and experiments and it is predicted that the planet will be host to both ground based and atmospheric investigations in the near future.
