Wind as a Geomorphic Agent in Cold Climates

This book was first published in 2004. Wind erosion and deposition are important factors in cold climates because of the open space and scarce vegetation. Aeolian processes connected with sand drift in polar environments are similar to those in deserts but in cold environments, frost and snow also play an important role. The Arctic is characterised by strangely eroded rocks, wind-formed lakes, sand dunes and loess deposits that owe their formation to aeolian processes controlled by frost and snow cover. Wind as a Geomorphic Agent in Cold Climates presents a detailed description and explanation of these wind-generated polar landforms. It includes numerous illustrations that will assist the reader in identifying and interpreting these features; both modern-day and those preserved in the geological record. This book provides an important introduction to this area of geocryology and will form a useful reference for graduate students and researchers in a variety of fields, including geomorphology, geology and environmental science. 'The title reflects the contents, and the author, precise, well-organized, clearly stated, an impressive contribution to the 'Studies in Polar Research' series.' Boreas Book Reviews 'This volume; adds a valuable and necessary contribution to the available material on cold climate processes and landforms. Although the effects of wind have been long recognized, this is the first volume to comprehensively deal with its attributes and effects in present and past cold environments ... this is a very valuable volume that fills a significant gap. The book is not only of direct interest to cold environment geomorphologists but should also interest biologists - and has direct connections with those interested in the role of wind in hot desert environments (for which the overlaps are many) ... I would also recommend it to anyone actively involved in cold environment geomorphic studies as a text you need in your office for quick and ready reference.' Antarctic Science '... an original and substantive book ... it provides a masterly overview that exposes the reader to some important, fascinating, but under-researched phenomena.'
