The new revised edition of a classic Earth science text This newly revised edition of Global Environment discusses the major elements of the geochemical cycles and global fluxes found in the atmosphere, land, lakes, rivers, biota, and oceans, as well as the human effects on these fluxes. Retaining the strengths of the original edition while incorporating the latest discoveries, this textbook takes an integrated, multidisciplinary, and global approach to geochemistry and environmental problems and introduces fundamental concepts of meteorology, surficial geology (weathering, erosion, and sedimentation), biogeochemistry, limnology, and oceanography. New concepts and information in this updated edition include changes of atmospheric carbon dioxide over geologic time, major advances in the study of chemical weathering of rocks, ocean acidification, and important environmental problems, such as the amelioration of the acid rain problem due to reduction in sulfur deposition, problems with nitrification of soils and lakes, and eutrophication of rivers and estuaries. An expanded chapter explores atmospheric chemistry and changing climate, with the most up-to-date statistics on CO2, the carbon cycle, other greenhouse gases, and the ozone hole. Only requiring a fundamental understanding in elementary chemistry, yet taking into account extensive and current data, this text is ideal for students in environmental geochemistry, environmental geology, global change, biogeochemistry, water pollution, geochemical cycles, chemical oceanography, and geohydrology, and serves as a valuable reference for researchers working on global geochemical and environmental issues. Revised edition takes a close look at global fluxes involving the atmosphere, land, lakes, rivers, biota, and oceans, and the human effects on these fluxes Detailed discussion of basic concepts including meteorology, surficial geology (weathering, erosion, and sedimentation), biogeochemistry, limnology, and oceanography An expanded up-to-date chapter on atmospheric chemistry and changing climate, including CO2, other greenhouse gases, and ozone Presentation of major advances in the study of chemical weathering Discussion of current environmental topics Global coverage of environmental problems involving water
Through an analysis of glass beads from four key study regions in Britain, the book aims to explore the role that this object played within the networks and relationships that constructed Iron Age society.
A new account of Elizabethan diplomacy with an original archival foundation, this book examines the world of letters underlying diplomacy and political administration by exploring a material text never before studied in its own right: the diplomatic letter-book. Author Elizabeth R. Williamson argues that a new focus on the central activity of information gathering allows us to situate diplomacy in its natural context as one of several intertwined areas of crown service, and as one of the several sites of production of political information under Elizabeth I. Close attention to the material features of these letter-books elucidates the environment in which they were produced, copied, and kept, and exposes the shared skills and practices of diplomatic activity, domestic governance, and early modern archiving. This archaeological exploration of epistolary and archival culture establishes a métier of state actor that participates in – even defines – a notably early modern growth in administration and information management. Extending this discussion to our own conditions of access, a new parallel is drawn across two ages of information obsession as Williamson argues that the digital has a natural place in this textual history that we can no longer ignore. This study makes significant contributions to epistolary culture, diplomatic history, and early modern studies more widely, by showing that understanding Elizabethan diplomacy takes us far beyond any single ambassador or agent defined as such: it is a way into an entire administrative landscape and political culture.
