Accelerating progress in the application of radioactive and stable isotope analysis to a varied range of geologicla and geochemical problems in geology has required a complete revision of Isotopes in the Earth Sciences, published in 1988.

Since 1956 the author has been making extensive and detailed investigations of saline lakes on the Qinghai-Tibet plateau.

An international symposium on `Ocean, River and Lakes: Energy and Substance Transfers at Interfaces' was held in Nantes, France in October 1996.

Even before the present Administrator of NASA, Daniel Goldin, made the phrase 'better, faster, cheaper' the slogan of at least the Office of Space Science, that same office under the Associate Administrator of Lennard Fisk and its Division of Solar System Exploration under the direction of Wes Huntress had begun a series of planetary spacecraft whose developmental cost, phase CID in the parlance of the trade, was to be held to under $150M.

The analysis of materials containing several elements used to be a difficult problem for analytical chemists, so a well established sequence of wet chemical qualitative tests were performed to ensure each element was detected.

Oceanographic discontinuities (e.

This book presents a compendium of molecular biology applications for the study of aquatic community ecology.

The Thirteenth International Conference on Basement Tectonics was held on the campus of Virginia Polytechnic Institute and State University in Blacksburg, Virginia from June 2 -6, 1997.

This is the first book to deal specifically with the procedures used in the analysis of structural relationships and the determination of structural successions in complexly deformed rocks such as migmatites and gneisses.

The workshop "e;From Dust to Terrestrial Planets"e; was initiated by a working group of planetary scientists invited to ISSI by Johannes Geiss in November 1997.

Research of the origins of life in connection with a marine environment started at the end of the seventies, when the `black smokers' in the Pacific were discovered and the Red Sea deep hydrothermal brines were found to be a fruitful environment for abiotic synthesis of life precursors.

Fission track dating is based on the microscopic observation and counting of etchable tracks left by the spontaneous fission of uranium in minerals.

Concentrations of dissolved organic matter (DOM) in lakes are often an order of magnitude greater than concentrations of particulate organic matter; nevertheless, the biogeochemical analysis of DOM is described in only a few textbooks on limnology (most thoroughly by Wetzel).

Carbon dioxide and other `greenhouse' gases are increasing in the atmosphere due to the burning of fossil fuels, the destruction of rain forests, etc.

Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors.

In the dozen years since the first edition appeared, there has been a great advance in understanding of the Earth's deep interior.

The future of the Common Fisheries Policy depends on progress in the relevant areas of research.

The sustainability of both natural and managed ecosystems is strongly influenced by soil biological processes.

This Special Issue of Water, Air and Soil Pollution offers original contributions from BIOGEOMON, an international symposium on ecosystem behavior and the evaluation of integrated monitoring of small catchments, held in Prague, Czech Republic, in September 1993.

It has long been realized that the mineral assemblages of igneous and metamorphic rocks may reflect the approach of a rock to chemical eCluilibrium during its formation.

Nowhere is the conflict between economic progress and environmental quality more apparent than in the mineral extraction industries.

Riverbank filtration is widely used in Europe and to some extent in the United States for the public water supply.

The chemical interaction of water and rock is one of the most fascinating an d multifaceted process in geology.

Following the long-standing tradition of the Seeheim-Workshops on Mossbauer Spectroscopy, 1978, 1983, 1988, 1994 always held in the same traditional place of the Lufthansa Training Center in Seeheim/Germany, the 5th workshop took place in 2002.

This volume arises from the NATO Advanced Research Workshop (ARW) on 'North African Cretaceous rudist and coral formations and their contributions to carbonate platform development , which was held in Tunisia, on 13-18 May, 2002.

The large and rapidly expanding body ofliterature related to nitrogen cycling in both managed and native terrestrial ecosystems reflects the importance accorded to the behaviour of this vital and often limiting nutrient.

The topic of sediment diagenesis is of fundamental importance to industry in the evaluation of hydrocarbon and water reservoir rocks.

For the first time in human history, developments in many branches of science provide us with an opportunity of formula- ting a comprehensive picture of the universe from its beginning to the present time.

It is presently well recognized that total concentrations of trace elements in any environmental compartment supply insufficient information to understand important phenomena.

Viewed from space, the Earth appears as a globe without a beginning or an end.

Several important developments in our understanding of the chemistry of weathering have occurred in the last few years: 1.

This book is written as a reference on organic substances in natural waters and as a supplementary text for graduate students in water chemistry.
