Beschreibung / Inhaltsverzeichnis: The oceans are an integral and important part of the global climate system. It is now widely accepted that human activities are inducing global climatic change. However, definitive evidence for climatic change driven by mankind remains elusive, despite extensive research. One reason for this is the significant role that oceans play in regulating the climate system's response to change. The oceans store immense amounts of heat and moisture, acting as a giant flywheel to the climate system, moderating change but prolonging it once change commences. The oceans also store vast amounts of atmospheric carbon dioxide, thus having a possible regulating effect on greenhouse warming driven by human activity. How is carbon dioxide and heat stored in the ocean? Are these mechanisms sensitive to climatic change? Could they interact with climatic change itself to accentuate or regulate such change? The exploration of these questions, among others, underlies this book. The interaction between the oceans and the atmosphere - and hence the climate - is complex and multi-faceted, requiring an understanding of many processes bridging conventional scientific disciplines. After a general introduction to the climate system, successive chapters describe how physical, biological and chemical processes combine to affect the ocean-atmosphere interaction over timescales from minutes to millenia, and their role in affecting climatic change in the past, present and future. This comprehensive textbook introducing the multi-disciplinary controls on the ocean-atmosphere interaction will prove an ideal course and reference book for undergraduates studying earth and environmental sciences, oceanography, meteorology and climatology. The book will also be useful for students and teachers of geography, physics, chemistry, and biology.
