DOWNLOAD EBOOKPolar ice cores have provided tremendous advances in our knowledge of past climate change. They also contain an archive of geochemical data, which can certainly delineate some of the forcing factors that govern climate change. However, our ability to interpret these data is severely curtailed by lack of knowledge of the processes governing the transfer of chemical species from the air to the snow. This book outlines the potential and problems of ice core chemistry and discusses the processes involved in air-snow transfer. It gives the state of current knowledge and an agenda for future research.

DOWNLOAD EBOOKThe Arctic troposphere (0 to ca. 8 km) plays an important role in environmental concerns for global change. It is a unique chemical reactor influenced by human activity and the Arctic ocean. It is surrounded by industrialized continents that in winter contribute gaseous and particulate pollution (Arctic haze). It is underlain by the flat Arctic ocean from which it is separated by a crack-ridden ice membrane 3 to 4 m thick. Ocean to atmosphere exchange of heat, water vapor and marine biogenic gases influence the composition of the reactor. From September 21 to December 21 to March 21, the region north of the Arctic circle goes from a completely sunlit situation to a completely dark one and then back to light. At the same time the lower troposphere is stably stratified. This hinders vertical mixing. During this light period, surface temperature reaches as low as -40°C. In this environment, chemical reactions involving sunlight are generally much slower than further south. Thus, the abundance of photochemically reactive compounds in the atmosphere can be high prior to polar sunrise. Between complete dark in February and complete light in April, a number of chemical changes in the lower troposphere take place.

DOWNLOAD EBOOKArctic haze is the phenomenon of large-scale industrial air pollution found all through the arctic air mass. Vertical profiles of air concentrations, obtained during several aircraft measurement programs in the Arctic, have offered the following explanation of arctic haze origin. Very long range, episodic transport of air masses over several thousand kilometers clearly affects the quality of arctic air during both summer and winter. Polluted air masses, carrying a mixture of anthropogenic and natural pollutants from a variety of sources in different geographical areas have been identified in the arctic atmosphere at altitudes from 2 to 4 or 5 km. The layers of polluted air at altitudes below 2.5 km can be traced to episodic transport of air masses from anthropogenic sources situated closer to the Arctic. Pollution material in arctic haze is of submicron size and contains a substantial fraction of black carbon: it interacts strongly with solar radiation. In addition, sulfate and a wide range of heavy metals appear, affecting their natural geochemical cycles. They also serve as indicators of major source regions of emissions in the world. This paper discusses what happens to the haze-related pollutants in the Arctic, what is the contribution of natural sources to the arctic haze and what are local and global effects of arctic haze. Some indications are given of the research to be undertaken in a view to assess the role of the Arctic in global change of the environment.

DOWNLOAD EBOOKArctic atmospheric pollution is now a major international issue. This volume presents the most authoritative review of this increasingly important subject for an audience of both scientists and administrators concerned with worldwide, as well as polar, pollution problems. Arctic Air Pollution is an edited collection of papers, first presented at a conference helo as the Scott Polar Research Institute in Cambridge in 1985. Building on foundations established at earlier meetings, this volume examines the problem of Arctic air pollution in an integrated, multidisciplinary fashion, with contributions from leading authorities in chemistry, ecology, climatology and epidemiology. To chemists, physicists and climatologists, it presents scientific problems. Ecologists are concerned with environmental threats; medical researchers with potential threats to human health. International lawyers and administrators are concerned with the legal implications of pollutants transferred across continents. Overall hangs the major question; can man-made pollution affect the delicate energy balance of the Arctic, and precipitate major climatic change worldwide?
