Book excerpt: One of Springer’s Major Reference Works, this book gives the reader a truly global perspective. It is the first major reference work in its field. Paleoclimate topics covered in the encyclopedia give the reader the capability to place the observations of recent global warming in the context of longer-term natural climate fluctuations. Significant elements of the encyclopedia include recent developments in paleoclimate modeling, paleo-ocean circulation, as well as the influence of geological processes and biological feedbacks on global climate change. The encyclopedia gives the reader an entry point into the literature on these and many other groundbreaking topics.
Download or read book Exploration of Antarctic Subglacial Aquatic Environments written by National Research Council and published by National Academies Press. This book was released on 2007-07-09 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antarctica is renowned for its extreme cold; yet surprisingly, radar measurements have revealed a vast network of lakes, rivers, and streams several kilometers beneath the Antarctic ice sheet. Sealed from Earth's atmosphere for millions of years, they may provide vital information about microbial evolution, the past climate of the Antarctic, and the formation of ice sheets, among other things. The next stage of exploration requires direct sampling of these aquatic systems. However, if sampling is not done cautiously, the environmental integrity and scientific value of these environments could be compromised. At the request of the National Science Foundation, this National Research Council assesses what is needed to responsibly explore subglacial lakes. Exploration of Antarctic Subglacial Aquatic Environments concludes that it is time for research on subglacial lakes to begin, and this research should be guided by internationally agreed upon protocols. The book suggests an initial protocol, which includes full characterization of the lakes by remote sensing, and minimum standards for biological and other types of contamination.
Download or read book The Two Mile Time Machine written by Richard B. Alley and published by Princeton University Press. This book was released on 2014-10-26 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1990s Richard B. Alley and his colleagues made headlines with the discovery that the last ice age came to an abrupt end over a period of only three years. In The Two-Mile Time Machine, Alley tells the fascinating history of global climate changes as revealed by reading the annual rings of ice from cores drilled in Greenland. He explains that humans have experienced an unusually temperate climate compared to the wild fluctuations that characterized most of prehistory. He warns that our comfortable environment could come to an end in a matter of years and tells us what we need to know in order to understand and perhaps overcome climate changes in the future. In a new preface, the author weighs in on whether our understanding of global climate change has altered in the years since the book was first published, what the latest research tells us, and what he is working on next.

Book excerpt: Rotary drilling equipment was modified and used to obtain cores from glaciers in Northwest Greenland, Byrd Station and Little America V, Antarctica. Using cold compressed air, specially designed bits and other modifications, cores were obtained to 1345 feet in Greenland, 1000 feet at Byrd Station and the Ross Ice Shelf was penetrated to a depth of 840 feet at Little America V. In all locations cracks in the core appeared with increasing frequency at depth due to the sudden release of the overburden load when the core was cut in the air-filled hole. Special equipment and techniques developed dealt with the problem with some success. (Author Modified Abstract).

Download or read book The EPICA DML Deep Ice Core written by Sérgio Henrique Faria and published by Springer. This book was released on 2017-09-20 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The line-scan images collected in this book represent the most accurate optical record of Antarctic ice cores ever presented, providing an invaluable resource for glaciologists and climate modellers, as well as a fascinating compilation of ice core images for Antarctica enthusiasts. Global warming and the Earth’s past climate are the two main reasons for extracting deep ice cores from Antarctica. Indeed, dust particles, aerosols and other climatic traces deposited on the snow surface, as well as the air trapped in bubbles by compacted snow, produce chronologically ordered strata, making the ice from Antarctica the most accurate and valuable archive of the Earth’s climate over the last million years. In addition, the layered structure produced by these strata, when revealed by appropriate methods, provides indispensable information concerning the flow and mechanical stability of the Antarctic ice sheet, allowing us to assess the current and future impact of global warming on the melting of polar ice caps with much greater precision.
