Book Description
Carbon Mineralization in Coastal Wetlands: From Litter Decomposition to Greenhouse Gas Dynamics fills the current knowledge gap in carbon mineralization, providing a balanced view of the carbon dynamics of coastal wetlands. This book provides a holistic treatment of carbon mineralization, from the contributions of litter/root decomposition pathways to carbon mineralization and the processes and sources of greenhouse gas production. This book compares carbon mineralization in coastal wetlands and highlights differences in carbon dynamics. As studies on blue carbon have strongly emphasized the storage potential of coastal wetlands, this book serves as an ideal resource on the topics discussed. Provides comprehensive perspectives on the processes and mechanisms of carbon mineralization in coastal wetlands Identifies factors regulating organic matter decomposition and greenhouse gas emission Clarifies the linkage between litter decomposition and greenhouse gas emission Unravels how greenhouse gas emissions are modified by anthropogenic activities, including eutrophication and deforestation

Book Description
Deep-water (below wave base) processes, although generallyhidden from view, shape the sedimentary record of more than 65% ofthe Earth’s surface, including large parts of ancientmountain belts. This book aims to inform advanced-levelundergraduate and postgraduate students, and professional Earthscientists with interests in physical oceanography and hydrocarbonexploration and production, about many of the important physicalaspects of deep-water (mainly deep-marine) systems. The authorsconsider transport and deposition in the deep sea, trace-fossilassemblages, and facies stacking patterns as an archive of theunderlying controls on deposit architecture (e.g., seismicity,climate change, autocyclicity). Topics include modern and ancientdeep-water sedimentary environments, tectonic settings, and howbasinal and extra-basinal processes generate the typicalcharacteristics of basin slopes, submarine canyons, contouritemounds and drifts, submarine fans, basin floors and abyssalplains.

Book Description
Barrier islands represent a complex coastal system that includes a number of different sedimentary depositional environments; nearshore zone, beach, dunes, washover fans, marshes, tidal flats, estuaries, lagoons, and tidal inlets. The morphodynamics of these fragile coastal systems provide a further complication to this coastal type. Although barrier islands comprise only 15% of the world's coastline, they have received a far greater proportion of attention from the scientific and engineering community, and more recently, from coastal managers and environmentalists. Modern barrier islands are arguably the most expensive and most vulnerable of all coastal environments. Pressure from developers for residential, industrial, and recreational development has caused most of our barriers to become significantly impacted by human activity, especially over the past few decades. These pres sures have led to extensive preservation of natural barriers through efforts from all levels of government and also by private organizations. Governments have also formed coastal management programs that help to control any future de velopment with the intent being to keep human activity compatible with barrier island morphodynamics. In order to devise appropriate coastal zone management programs, it is necessary to have a comprehensive understanding of the morpho dynamics of barrier island systems. This volume provides comprehensive details on barrier island morphology, sediment distribution, and the process-response mechanisms that cause changes to both. These are the important aspects of barrier systems that can provide important input into the development and implementation of coastal management programs.

Book Description
The first edition appeared fourteen years ago. Since then there have been significant advances in our science that warrant an updating and revision of Sand and Sandstone. The main framework of the first edition has been retained so that the reader can begin with the mineralogy and textural properties of sands and sandstones, progress through their organization and classification and their study as a body of rock, to consideration of their origin-prove nance, transportation, deposition, and lithification-and finally to their place in the stratigraphic column and the basin. The last decade has seen the rise of facies analysis based on a closer look at the stratigraphic record and the recognition of characteristic bed ding sequences that are the signatures of some geologic process-such as a prograding shallow-water delta or the migration of a point bar on an alluvial floodplain. The environment of sand deposition is more closely determined by its place in such depositional systems than by criteria based on textural characteristics-the "fingerprint" approach. Our revi sion reflects this change in thinking. As in the geological sciences as a whole, the concept of plate tectonics has required a rethinking of our older ideas about the origin and accumu lation of sediments-especially the nature of the sedimentary basins.

Book Description
This volume is based on the proceedings of a conference held at Florida State University in April, 1978. This conference was supported by the Florida State University Graduate Research Council, the Department of Biological Science (F. S. U. ), and the Center for Professional Development and Public Service. Particular recogni tion should be made of the efforts of Dr. Anne Thistle in the organization of the conference and the completion of this book. Julia K. White and Sheila Marrero produced the typescript. The principal objective of the conference was to assemble a group of marine scientists from diverse disciplines to discuss the state of marine ecology with particular attention to new research directions based on previous studies. Emphasis was placed on the integration of different research approaches and on the application of established procedures to various environmental problems. An effort was made to eliminate traditional disciplinary boundaries which often hinder our understanding of marine systems. There was generally wide latitude for review and speculation concerning such topics as physico-chemical processes, productivity and trophic interactions, population distribution and community structure, and natural or anthropogenic disturbance phenomena. Throughout, the usual miniaturization of the scope of discussion was subordinate to a frank appraisal of the present status of marine research. Although many introductory ecological texts stress the so called ecosystem approach, individual marine research projects seldom encompass this broad course. There is, in fact, a real need for system-wide studies at both the theoretical and applied levels.

Book Description
Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils. Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota and soil fauna are collective terms that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface. Soils are rich ecosystems, composed of both living and non-living matter with a multitude of interaction between them. Soils play an important role in all of our natural ecological cycles. They also provide benefits through their contribution in a number of additional processes, called ecosystem services. These services range from waste decomposition to acting as a water filtration system to degrading environmental contaminants. Soil biochemistry is one of the branches of soil science dealing with the formation and decomposition of soil organic matter, biochemical reactions of carbon, nitrogen, phosphorus, sulfur, metals and xenobiotic in soils, and biochemistry of the plant-root rhizosphere. The book will suit to the needs of students, teachers, scholars and general readers.

Book Description
We wrote Sedimentology of Shale primarily because we lacked a handy, reasonably comprehensive source of information and ideas about shales for students in our sedimentology program. It was also our feeling that the time for shales to receive more study had finally arrived. Sedimentology of Shale also seems very timely because today more sedimentologists are interested in shales. Certainly in the last five years the pace of shale research has no ticeably quickened because the role of shales as important sources of oil, gas, heavy metals and as a long understudied part of the earth's geologic his tory has been recognized. Noteworthy developments include the elucida tion of the importance of trace fossils in shales, the discovery of thick sequences of overpressured shales in regions such as the Gulf Coast (which have important implications for hydrocarbon migration and faulting), the ex tension of the principles of metamorphic facies to the realm of low tempera ture diagenesis by study of the organic matter in shales, and shales as ul timate sources for mineral deposits. Accordingly, we decided it was timely to write a book on shales. In one respect, however, ours is an unusual book. Most books in geology are produced after one or two decades of progress have been made in a field and attempt to summarize and evaluate that progress.
