The systematic description of the knowledge accumulated on the physical oceanography, marine chemistry and pollution, and marine biology of the Caspian Sea forms the basis of this book. It presents the principal characteristic features of the environmental conditions of the sea and their changes in the second half of the 20th century. At present, the principal problems of the Caspian Sea are related to the interannual sea level changes and their forecast and to the estimation of the intensity of the chemical pollution of the sea and its impact upon the biota. Special attention is paid to socio-economic, legal, and political issues in the Caspian Sea region. This publication is based on numerous observational data collected by the authors of the chapters during sea expeditions, on the archive data of several Russian oceanographic institutions, as well as on the broad scientific literature mainly published in Russian editions. This book is addressed to the specialists concerned with research in various fields of physical oceanography, marine chemistry, pollution studies, and biology; solving a wide scope of problems from the regional climate to the mesoscale processes; and using a variety of methods from remote sensing of the seas to numerical and laboratory modeling.

Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the ?rst objectives of Environmental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Envir- mental Chemistry. We have now synthesized and described over ?ve million chemical compounds and chemical industry produces about hundred and ?fty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modi?cations, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and con?ned areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

The situation of the Aral Sea is known as one of the worst man-made environmental crises of the twentieth and twenty-first centuries. Many have seen the satellite photos evidencing the startling shrinkage and deterioration of the sea, as it was a few decades ago and how it appears today. Whereas the Aral Sea was the world's fourth-largest inland body of water in 1960, it has now shrunk to a small fraction of that within three increasingly saline and polluted parts, primarily due to the diversion of waters for agricultural irrigation. The Aral Sea Encyclopedia is devoted to the remarkable phenomenon of the possibility of Aral Sea's imminent disappearance from the Earth in the time span of a single human generation. It first describes the sea before it started drying-out, and then the actions and efforts of the Central Asian countries, as well as the international community, to mitigate the socioeconomic and environmental hazards caused by this desiccation and increasing salinity. This comprehensive reference not only addresses the key environmental issues and presents national and international programs.It also documents the history of the related research studies, the involvement of prominent historical figures, and the chronology of events over three centuries, which became the milestones in the economic development of the Aral Sea and its subsequent diminution.The publication of the Aral Sea Encyclopedia initiates a group of similar valuable references that gather multi-disciplinary perspectives on the world's seas, including planned volumes on the Caspian and Black Seas and the Sea of Japan.

With remarkable vision, Prof. Otto Hutzinger initiated The Handbook of Envir- mental Chemistry in 1980 and became the founding Editor-in-Chief. At that time, environmental chemistry was an emerging ?eld, aiming at a complete description of the Earth's environment, encompassing the physical, chemical, biological, and geological transformations of chemical substances occurring on a local as well as a global scale. Environmental chemistry was intended to provide an account of the impact of man's activities on the natural environment by describing observed changes. While a considerable amount of knowledge has been accumulated over the last three decades, as re?ected in the more than 70 volumes of The Handbook of Environmental Chemistry, there are still many scienti?c and policy challenges ahead due to the complexity and interdisciplinary nature of the ?eld. The series will therefore continue to provide compilations of current knowledge. Contri- tions are written by leading experts with practical experience in their ?elds. The Handbook of Environmental Chemistry grows with the increases in our scienti?c understanding, and provides a valuable source not only for scientists but also for environmental managers and decision-makers.Today, the series covers a broad range of environmental topics from a chemical perspective, including methodol- ical advances in environmental analytical chemistry.

The ‘‘Aral Sea Encyclopedia’’ is the first one in the new series of encyclopedias about the seas of the former Soviet Union. Preparing it we faced certain difficulties. The thing is that this encyclopedia is a monument to the sea that is disappearing during our lifetime. The world community considers the situation with the Aral Sea and all changes that occurred in its whereabouts in the recent decades as one of the most serious, if not disastrous anthropogenic environmental crises of the 20th century. Before 1960, this was a water-abundant sea-lake that was fourth among world lakes after the Caspian Sea (USSR, Iran), the Great Lakes (USA, Canada) and Victoria Lake (Africa). This was a real ‘‘pearl’’ among the sands of the largest deserts, the Karakums and the Kyzylkums. Navigation between the sea ports Muinak and Aralsk and fisheries famous for the Aral breams, barbells, sturgeons, shemaya, and others were developed here. One could find beautiful recreational zones and beaches here. The deltas of the Amudarya, the major river of Central Asia, and the Syrdarya bringing their waters into the Aral Sea were famous for their biodiversity, fishery, muskrat rearing, reed prod- tion. The local population found occupations related to the water infrastructure.

“The Caspian Sea Encyclopedia” is the second one in the new series of encyclo- dias about the seas of the former Soviet Union published by Springer-Verlag. The ?rst volume – “The Aral Sea Encyclopedia” was published by Springer in 2009. The series will be continued by “The Black Sea Encyclopedia” in 2010. Today the Caspian Sea is known to readers thanks to its oil and gas resources, sturgeon and caviar, signi?cant sea-level variations, socio-economic and political problems. The Caucasus and Central Asia (http://eurodialogue. org/?les/fckeditor_?les/Caspian-s- map2. png) vii viii Introduction For more than 250 years the Caspian Sea was shared by two states: Russia (the Soviet Union) and Persia (Iran). After the disintegration of the USSR in 1992, the new independent states of Azerbaijan, Turkmenistan and Kazakhstan have radically changed the political and economic situation in the region. In addition to Russia and Iran, who had determined the situation on the Caspian for a long period, Azerbaijan, Turkmenistan and Kazakhstan are now interested parties, beginning a new stage in the historical development of the Caspian region. This increase in the number of the Caspian legal entities from two to ?ve has given rise to a whole tangle of geopolitical, economic, international legal, ethnic and environmental problems, each of which demands its own approach and settlement mechanism.
