Proceedings of a symposium, Vienna, 19-23 April 1993. Natural isotopes are among the most powerful tools for investigating past and current environmental changes. In particular, stable isotopes have proved to be very useful proxy indicators of climate related parameters such as surface air temperature, relative humidity of the atmosphere and amount of precipitation, whereas radioactive isotopes are widely used as a dating tool. The release of radionuclides during nuclear bomb tests permitted studies of the dynamics of transport and mixing processes in the atmosphere. It also allowed a global tracer experiment on the hydrological and carbon cycles, which substantially contributed to better understanding of these two vital compartments of the global ecosystem. A wide spectrum of themes was discussed at the symposium, covering both the 'present' and the 'past' of the global atmosphere/hydrosphere system. Case studies as well as methodological aspects of various isotope techniques applied in both areas of research were presented.

Proceedings of a symposium on Isotope Techniques in the Study of Past and Current Environmental Changes in the Hydrosphere and the Atmosphere, Vienna, 14-18 April 1997. The symposium was structured in five sessions of oral presentations, a poster session and a round table discussion that focused on trends and future requirements in isotope hydrology and on applications in climate and environmental research. The major themes covered by the presentations included the use of isotopic tracers in studies of atmospheric and hydrospheric changes and of human impacts on water and the environment. Special emphasis was placed on isotopic archives of climatic and environmental change. Some contributions addressed new technical approaches.

This book covers the distribution, hydrochemistry and geophysics of the naturally occurring stable isotopes namely: hydrogen, oxygen and radioactive tritium, carbon and other cosmogenic and radiogenic isotopes of the uranium-thorium series, in the oceans and in atmosphere, the earth's surface and ground water. The use of environmental isotopes in the three main areas of natural waters is discussed: origin, dynamics and residence time in natural reservoirs. The origin of the hydrosphere is examined in the light of isotopic, new cosmochemical and recent theoretical results. The book will be of interest to scientists and researchers who use environmental isotopes in solving scientific and practical problems in hydrology, hydrogeology, oceanography, meteorology, hydrogeochemistry and cosmochemistry. Lecturers, students and postgraduates in these fields will also find it useful.

This book focuses on two complementary time-scales, the Holocene (approximately the last 11,500 years) and the last glacial-interglacial cycle (approximately the last 130,000 years) to synthesize evidence of climate variability at the regional and continental scale across Europe and Africa. This is the first examination of historical climate variations at such a scale, and thus sets a benchmark for future research.

This book provides a unique, in-depth view of past, present and potential future climatic change in mountain regions, and in particular on the mechanisms which are responsible for this change. Other books which focus on environmental change in mountains focus more generally on the impacts of this change on mountain systems, rather than on the regional features of climatic change itself. The book enters into a high level of detail concerning results of international investigations which involve specialists from numerous climate-related disciplines. The book can be used in an academic and research context, for advanced graduate and doctoral students, as well as researchers working in various domains of relevance to climatic change issues. The book also has relevance in the context of future activities of the Intergovernmental Panel on Climate Change (IPCC), in terms of providing up-to-date knowledge of fundamental mechanisms and consequences of climatic change in mountain regions.

The goal of this book is to examine the complex state of radioactivity in the environment, and to understand the interplay of its two principal sources: man-made and natural. The text examines human contributions to release of radionuclides, with an eye to future reductions, and assesses natural occurrences in an evaluation of baseline radioactivity.

The majesty of the icefields is beyond description. He who has been fortunate to be there once, remains bound forever. To a theoretical physicist working on black holes the icefields produce a familiar vertigo, the instinctive certainty of being confronted with something so simple and beautifully extreme that it must be of importance. The meeting whose proceedings are contained in this volume was conducted onboard of a vessel that went to the icefields, and the participants could literally set foot on them. It was expected that, for those who had not been there before, this would constitute a ritual of initiation. And so it did. For this reason we like to refer to the meeting as an expedition because, although it did not have the hardship, it had the spirit. After this foundational expedition there have been two others, this time both with spirit and hardship, one from Chile and one from Argentina. At the moment of this writing, a fourth, full-fledged airborne expedition to the icefields is about to depart from Valdivia. Many of the people of many nations who were on board of the Aquiles will take part in it. We look forward to its results, and to an ongoing exciting scientific adventure. Claudio Teitelboim Director, Centro de Estudios Cientfficos Valdivia, September 2001 v ACKNOWLEDGMENTS This volume is the result of the effort and generosity of many people and institutions.

Environmental isotope and nuclear techniques provide unmatched insights into the processes governing the water cycle and its variability. This monograph presents state of the art applications and new developments of isotopes in hydrology, environmental disciplines and climate change studies. Coverage ranges from the assessment of groundwater resources in terms of recharge and flow regime to studies of the past and present global environmental and climate changes.
