This book provides a general survey of Geocryology, which is the
study of frozen ground called permafrost. Frozen ground is the
product of cold climates as well as a variety of environmental
factors. Its major characteristic is the accumulation of large
quantities of ice which may exceed 90% by volume. Soil water
changing to ice results in ground heaving, while thawing of this
ice produces ground subsidence often accompanied by soil flowage.
Permafrost is very susceptible to changes in weather and climate as
well as to changes in the microenvironment. Cold weather produces
contraction of the ground, resulting in cracking of the soil as
well as breakup of concrete, rock, etc. Thus permafrost regions
have unique landforms and processes not found in warmer lands. The
book is divided into three parts. Part 1 provides an introduction
to the characteristics of permafrost. Four chapters deal with its
definition and characteristics, the unique processes operating
there, the factors affecting it, and its general distribution. Part
2 consists of seven chapters describing the characteristic
landforms unique to these areas and the processes involved in their
formation. Part 3 discusses the special problems encountered by
engineers in construction projects including settlements, roads and
railways, the oil and gas industry, mining, and the agricultural
and forest industries. The three authors represent three countries
and three language groups, and together have over 120 years of
experience of working in permafrost areas throughout the world. The
book contains over 300 illustrations and photographs, and includes
an extensive bibliography in order to introduce the interested
reader to the large current literature. Finalist of the 2019 PROSE
Awards.
