(Received November I, 1984; revised May 14, 1985) Abstract. An integrated, interdisciplinary, intensive study of three forested watersheds in the Adirondack Park region of New York State was started in 1977 to quantify the relationship between the deposition of atmospheric acids and surface water acidity. A general mechanistic theory of lake-watershed acidification that takes into account the production and consumption of acidity by watershed processes, as well as atmospheric inputs of acidity, was developed. This theory is formulated as a mathematical simulation model. Model and data analyses establish the importance of using an integrated ecosystem perspective to assess the vulnerability of surface waters to acidification by acidic deposition. The acid-base status of surface waters is determined by the interaction of many factors: soil, hydrologic, vegetation, geologic, climatic, atmospheric. The absolute and relative contribution of any given factor can be highly variable, both geographically and temporally; hence, lake sensitivity to changes in the quality and quantity of atmospheric deposition is also highly variable.

Acidic deposition and its effect on aquatic ecosystems have become major scientific and public policy issues in the United States since the early 1970s, and many diverse studies have been completed. This book is the first comprehensive, integrated synthesis of available information on current and potential effects of acidic precipitation on lakes and streams in geographic regions with a high number of low-alkalinity surface water from the Adirondacks and the Southern Blue Ridge to the Upper Midwest to the Rocky Mountains, the Sierra Nevada, and the Cascades. Written by leading authors, the book examines the current status of water chemistry and characterizes the processes controlling water chemistry on a regional basis by using and comparing high-quality data sets. Methods for the assessment of long-term changes in water chemistry and their effects in fish and other biota are also presented. The book amply illustrates the substantial diversity among geographical regions with respect to the nature of surface waters and the complexity of their response to acidic deposition. This volume will be of great interest to researchers in limnology, aquatic ecology, environmental chemistry, hydrology, and atmospheric sciences. It will also serve as an important reference for environmental managers and policy makers.

The completion of the initial phase of the U.S. National Acid Precipitation Assessment Program (NAPAP) in 1990 marked the end of the largest environmental research and assessment effort to that time. The resulting series of 27 State of Science and Technology (SOS/T) Reports and the NAPAP Integrated Assessment represent a decade of work by hundreds

A lake, as a body of water, is in continuous interaction with the rocks and soils in its drainage basin, the atmosphere, and surface and groundwaters. Human industrial and agricultural activities introduce new inputs and processes into lake systems. This volume is a selection of ten contributions dealing with diverse aspects of lake systems, including such subjects as the geological controls of lake basins and their histories, mixing and circulation patterns in lakes, gaseous exchange between the water and atmosphere, and human input to lakes through atmospheric precipitation and surficial runoff. This work was written with a dual goal in mind: to serve as a textbook and to provide professionals with in-depth expositions and discussions of the more important aspects of lake systems.
