Book excerpt: pH is a master variable that controls many chemical reactions in nature due to the abundance of acids and bases in the Earth environment. A novel method for continuously measuring pH and acidity in ice cores is applied here to the analysis of ice core arrays from Greenland and Antarctica. The Greenland array documents the history of acidic deposition in a location that is downwind from the major air polluting regions of North America. Comparisons show that the ice core records closely track precipitation chemistry data from North America, available since 1979, thus enabling the ice cores to serve as a valid proxy for the history of acid deposition in North America since industrialization began in the mid-1800s. Ice core observations suggest that the natural background of sulfur acidity declined during the 20 th century and this decline is attributed to decreased biogenic sulfur emissions associated with changing sea ice conditions in the North Atlantic Ocean. Acidity records from Antarctica are utilized in a comprehensive assessment of the primary acid-anions and base-cations, including nitrate, sulfate, ammonium, and chloride. Arrays from high and low snow accumulation regions are exploited for their strengths in providing subannual resolution and long duration records, respectively. Biomass burning is found to be the source of a significant portion of the nitrate and ammonium that reaches Antarctica based on high correlations with published methane isotopes and measured black carbon data, respectively. Chloride at the low accumulation sites is found to be a heavily diffused version of the original sea salt aerosol record, the latter of which is linked to cooler ocean temperatures, possibly through the sea ice mechanism for sea salt aerosol production.

Available in PDF, EPUB and Kindle. Book excerpt: This updated and expanded version of the second edition explains the physical principles underlying the behaviour of glaciers and ice sheets. The text has been revised in order to keep pace with the extensive developments which have occurred since 1981. A new chapter, of major interest, concentrates on the deformation of subglacial till. The book concludes with a chapter on information regarding past climate and atmospheric composition obtainable from ice cores.

This book was released on 2013-06-29 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of polar ice cores has proven to be very instructive about past environmental conditions on the time scale of several climatic cycles, and recent drilling operations have provided information of great value for global change issues. The book presents the most recent data extracted from Greenland ice cores and surface experiments and compares them with former Antarctic results. It contains background articles, original contributions and group reports of interest to scientists, climatologists, atmospheric chemists, and glaciologists involved in global change research.

Book excerpt: This beautifully illustrated book reviews the development of science in Antarctica from its early beginnings, in the age of Captain Cook, to the present complexity of the 1980s when research teams from many nations work side by side. Three major areas, biological science, the earth sciences and atmospheric science are examined individually, highlighting the principal achievements of the past 25 years, and providing an up-to-date account of our present understanding of this frozen continent. Concern over the future of the Antarctic Treaty and the probable main directions of future research, provide an indication of the importance of Antarctica to all scientific disciplines. This unique natural laboratory for science is now being investigated by eighteen countries. International interest in Antarctica grows apace and, whatever its future use by mankind, its sensible management will require a good, scientific basis.
