Opis

The Arctic is characterized by strangely eroded rocks, special wind-formed lakes, sand dunes and loess deposits that owe their formation to aeolian processes controlled by snow cover and frost formation. This book presents a detailed description and explanation of these wind-generated polar landforms, modern-day as well as those preserved in the geological record. It is an important introduction to this area of geocryology and a useful reference for graduate students and researchers in geomorphology, geology and environmental science.

Recenzje

'… an original and substantive book … it provides a masterly overview that exposes the reader to some important, fascinating, but under-researched phenomena.' Progress in Physical Geography
