Originally published in 1986, The Permafrost Environment examines how the search for oil, gas and minerals in the arctic region instigated new and vitally important needs to understand the permafrost environment. The construction of roads, airfields, buildings and pipelines in this inhospitable environment has posed enormous problems for engineers and geologists. This book is a comprehensive review of the nature of the permafrost environment and its utilization. It looks at environmental processes and their effects and examines the management problems which result. It provides a detailed look at how normal procedures for construction etc. need to be modified to cope with the special conditions and it gives examples from throughout the arctic region, including Canada, Siberia, Alaska, Greenland and Northern Scandinavia.

Exploring one of the greatest potential contributors to climate change—thawing permafrost—and the anxiety of extinction on an increasingly hostile planet Climate scientists point to permafrost as a “ticking time bomb” for the planet, and from the Arctic, apocalyptic narratives proliferate on the devastating effects permafrost thaw poses to human survival. In Earth, Ice, Bone, Blood, Charlotte Wrigley considers how permafrost—and its disappearance—redefines extinction to be a lack of continuity, both material and social, and something that affects not only life on earth but nonlife, too. Earth, Ice, Bone, Blood approaches the topic of thawing permafrost and the wild new economies and mitigation strategies forming in the far north through a study of the Sakha Republic, Russia’s largest region, and its capital city Yakutsk, which is the coldest city in the world and built on permafrost. Wrigley examines people who are creating commerce out of thawing permafrost, including scientists wishing to recreate the prehistoric “Mammoth steppe” ecosystem by eventually rewilding resurrected woolly mammoths, Indigenous people who forage the tundra for exposed mammoth bodies to sell their tusks, and government officials hoping to keep their city standing as the ground collapses under it. Warming begets thawing begets economic activity— and as a result, permafrost becomes discontinuous, both as land and as a social category, in ways that have implications for the entire planet. Discontinuity, Wrigley shows, eventually evolves into extinction. Offering a new way of defining extinction through the concept of “discontinuity,” Earth, Ice, Bone, Blood presents a meditative and story-focused engagement with permafrost as more than just frozen ground.

Most of the Earth’s biosphere is characterized by low temperatures. Vast areas (>20%) of the soil ecosystem are permanently frozen or are unfrozen for only a few weeks in summer. Permafrost regions occur at high latitudes and also at high ele- tions; a significant part of the global permafrost area is represented by mountains. Permafrost soils are of global interest, since a significant increase in temperature is predicted for polar regions. Global warming will have a great impact on these soils, especially in northern regions, since they contain large amounts of organic carbon and act as carbon sinks, and a temperature increase will result in a release of carbon into the atmosphere. Additionally, the intensified release of the clima- relevant tracer gas methane represents a potential environmental harzard. Significant numbers of viable microorganisms, including bacteria, archaea, p- totrophic cyanobacteria and green algae, fungi and protozoa, are present in per- frost, and the characteristics of these microorganisms reflect the unique and extreme conditions of the permafrost environment. Remarkably, these microorg- isms have been reported to be metabolically active at subzero temperatures, even down to ?20°C.

This book provides a cross-disciplinary overview of permafrost and the carbon cycle by providing an introduction into the geographical distribution of permafrost, with a focus on the distribution of permafrost and its soil carbon reservoirs. The chapters explain the basic physical properties and processes of permafrost soils: ice, mineral and organic components, and how these interact with climate, vegetation and geomorphological processes. In particular, the book covers the role of the large quantities of ice in many permafrost soils which are crucial to understanding carbon cycle processes. An explanation is given on how permafrost becomes loaded with ice and carbon. Gas hydrates are also introduced. Structures and processes formed by the intense freeze-thaw action in the active layer are considered (e.g. ice wedging, cryoturbation), and the processes that occur as the permafrost thaws, (pond and lake formation, erosion). The book introduces soil carbon accumulation and decomposition mechanisms and how these are modified in a permafrost environment. A separate chapter deals with deep permafrost carbon, gas reservoirs and recently discovered methane emission phenomena from regions such as Northwest Siberia and the Siberian yedoma permafrost.
