This book takes an in-depth look at the theory and methods inherent in the tracing of riverine sediments. Examined tracers include multi-elemental concentration data, fallout radionuclides (e.g., 210Pb, 137Cs, 7Be), radiogenic isotopes (particularly those of Pb, Sr, and Nd), and novel (“non-traditional”) stable isotopes (e.g., Cd, Cu, Hg, and Zn), the latter of which owe their application to recent advances in analytical chemistry. The intended goal is not to replace more ‘traditional’ analyses of the riverine sediment system, but to show how tracer/fingerprinting studies can be used to gain insights into system functions that would not otherwise be possible. The text, then, provides researchers and catchment managers with a summary of the strengths and limitations of the examined techniques in terms of their temporal and spatial resolution, data requirements, and the uncertainties in the generated results. The use of environmental tracers has increased significantly during the past decade because it has become clear that documentation of sediment and sediment-associated contaminant provenance and dispersal is essential to mitigate their potentially harmful effects on aquatic ecosystems. Moreover, the use of monitoring programs to determine the source of sediments to a water body has proven to be a costly, labor intensive, long-term process with a spatial resolution that is limited by the number of monitoring sites that can be effectively maintained. Alternative approaches, including the identification and analysis of eroded upland areas and the use of distributed modeling routines also have proven problematic. The application of tracers within riverine environments has evolved such that they focus on sediments from two general sources: upland areas and specific, localized, anthropogenic point sources. Of particular importance to the former is the development of geochemical fingerprinting methods that quantify sediment provenance (and to a much lesser degree, sediment-associated contaminants) at the catchment scale. These methods have largely developed independently of the use of tracers to document the source and dispersal pathways of contaminated particles from point-sources of anthropogenic pollution at the reach- to river corridor-scale. Future studies are likely to begin merging the strengths of both approaches while relying on multiple tracer types to address management and regulatory issues, particularly within the context of the rapidly developing field of environmental forensics.

Tracers in Hydrology and Water Research is a comprehensive overview of the application of natural and artificial tracers in hydrology and environmental research. Taking a unique approach by providing the reader with a systematic and state of the art description of natural and artificial tracers, the book also covers key analytical techniques and applications, and modern tracer methods in the context of systematic hydrology. Tracers have become a primary tool for process investigation, qualitative and quantitative system analysis and integrated resource management. This book will outline the fundamentals of the subject, and examine the latest research findings, clearly showing the entire process of tracer application through the inclusion of numerous integrated case studies. As many techniques derive from different scientific disciplines (chemistry, biology, physics), the effort of compilation and integration into modern hydrology and environmental science research and application requires substantial continuity and experience, which certifies this group of authors. This book will be an invaluable reference not only for students and researchers within the field of Hydrology and Hydrogeology but also for engineers and other tracer techniques applying users.

This work summarizes the historical progression of the field of lithium (Li) isotope studies and provides a comprehensive yet succinct overview of the research applications toward which they have been directed. In synthesizing the historical and current research, the volume also suggests prospective future directions of study. Not even a full decade has passed since the publication of a broadly inclusive summary of Li isotope research around the globe (Tomascak, 2004). In this short time, the use of this isotope system in the investigation of geo- and cosmochemical questions has increased dramatically, due, in part, to the advent of new analytical technology at the end of the last millennium. Lithium, as a light element that forms low-charge, moderate-sized ions, manifests a number of chemical properties that make its stable isotope system useful in a wide array of geo- and cosmochemical research fields.

Water quality and management are of great significance globally, as the demand for clean, potable water far exceeds the availability. Water science research brings together the natural and applied sciences, engineering, chemistry, law and policy, and economics, and the Treatise on Water Science seeks to unite these areas through contributions from a global team of author-experts. The 4-volume set examines topics in depth, with an emphasis on innovative research and technologies for those working in applied areas. Published in partnership with and endorsed by the International Water Association (IWA), demonstrating the authority of the content Editor-in-Chief Peter Wilderer, a Stockholm Water Prize recipient, has assembled a world-class team of volume editors and contributing authors Topics related to water resource management, water quality and supply, and handling of wastewater are treated in depth

Handbook of Environmental Isotope Geochemistry, Volume 2: The Terrestrial Environment, B focuses on the processes, methodologies, principles, and approaches involved in isotope geochemistry. The selection first elaborates on mathematical models for the interpretation of environmental radioisotopes in groundwater systems; isotopes in cloud physics; and environmental isotopes in lake studies. Discussions focus on water balance studies of lakes, isotopic fractionations during evaporation of water, study of hailstone growth mechanisms by means of isotopic analyses, isotopic effects during growth of individual elements, and models and their hydrological significance. The text then takes a look at environmental isotope and anthropogenic tracers of lake sedimentation; stable isotope geochemistry of travertines; and isotope geochemistry of carbonates in the weathering zone. Topics include isotopic composition of carbonates in the weathering zone; reprecipitation processes in the weathering zone; isotopic composition of carbon and oxygen sources in the weathering zone; and geochemical conditions controlling travertine deposition. The manuscript also reviews radioactive noble gases in the terrestrial environment, isotope effects of nitrogen in the soil and biosphere, and oxygen and hydrogen isotope geochemistry of deep basin brines. The selection is a vital source of data for researchers interested in isotope geochemistry.

The evolution of the Argentina Continental Margin during the Quaternary and the stratigraphic and morphosedimentary configuration responded to climatic variability, oceanographic changes, glacioeustatic fluctuations and tectono-isostatic processes, which began to impact on the margin during previous geological periods. The final modeling of the margin was achieved in the late Miocene, when the interaction between the Antarctic and North Atlantic water-masses favored climatic and oceanographic changes with a profound effect on morphosedimentary features. In the Quaternary, the different regions of the margin distinctly responded to such changes. Whereas in the shelf the main modeling factors were the sea-level fluctuations of glacioeustatic origin and consequent marine-continental stratigraphic records, in the slope (particularly in the sector corresponding to the passive margin) the prevailing effect was the interaction between water-masses and the sea floor, giving origin to contouritic depositional systems accompanied of gravity processes responsible of turbiditic and mass-wasting deposits. Different relationships between contouritic and turbiditic facies respond to distinct combinations of oceanic circulation variability and the indirect effect on the sea floor of sea-level fluctuations. As a result of this complexity in the regional processes in the framework of the broad hemispheric oceanographic-climatic conditioning factors, the ACM can be considered as a complete archive for the Southern Ocean.
