Biogeochemistry

Biogeochemistry, Third Edition, considers how the basic chemical conditions of the Earth-from atmosphere to soil to seawater-have been and are being affected by the existence of life. This expansive text pulls together the numerous fields of study encompassed by biogeochemistry to analyze the increasing demands of the growing human population on limited resources and the resulting changes in the planet's chemical makeup. It employs current technology to help students extrapolate small-scale examples to the global level, and also discusses the instrumentation being used by NASA and its role in studies of global change. With the Earth's changing chemistry as the focus, this book provides an excellent framework for courses examining global change and environmental chemistry, and will also be a useful self-study guide. This edition calculates and compares the effects of industrial emissions, land clearing, agriculture, and rising population on Earth's chemistry. It also synthesizes the global cycles of carbon, nitrogen, phosphorous, and sulfur, and suggests the best current budgets for atmospheric gases such as ammonia, nitrous oxide, dimethyl sulfide, and carbonyl sulfide. It includes an extensive review and up-to-date synthesis of the current literature on the Earth's biogeochemistry. Answers to end of chapter problem sets are available on the instructor's companion website. This book will appeal to upper-division undergraduate and graduate students in geochemistry, ecology, earth, and soil sciences, especially those with interest in global change or environmental chemistry. - Calculates and compares the effects of industrial emissions, land clearing, agriculture, and rising population on Earth's chemistry- Synthesizes the global cycles of carbon, nitrogen, phosphorous, and sulfur, and suggests the best current budgets for atmospheric gases such as ammonia, nitrous oxide, dimethyl sulfide, and carbonyl sulfide- Includes an extensive review and up-to-date synthesis of the current literature on the Earth's biogeochemistry
