Permafrost

By tracing the English word permafrost back to its Russian roots, this unique intellectual history uncovers the multiple, contested meanings of permafrost as a scientific idea and environmental phenomenon.

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.

Visual and performance artist, and winner of the inaugural Kill Your Darlings Manuscript Award, SJ Norman turns their hand to fiction with spectacular results. Permafrost explores the shifting spaces of desire, loss and longing. Inverting and queering the gothic and romantic traditions, each story represents a different take on the concept of a haunting or the haunted. Though it ranges across themes and locations &– from small-town Australia to Hokkaido to rural England &– this collection is united by the power of the narratorial voice, with its auto-fictional resonances, dark wit and swagger. Whether recounting the confusion of a child trying to decipher their father and stepmother's new relationship, the surrealness of an after-hours tour of Auschwitz, or a journey to wintry Japan to reconnect with a former lover, Permafrost unsettles, transports and impresses in equal measure.

Once Upon the Permafrost is a longitudinal climate ethnography about "knowing" a specific culture and the ecosystem that culture physically and spiritually depends on in the twenty-first-century context of climate change. Through careful integration of contemporary narratives, on-site observations, and document analysis, Susan Alexandra Crate shows how local understandings of change and the vernacular knowledge systems they are founded on provide critical information for interdisciplinary collaboration and effective policy prescriptions.

A LOCUS AWARD FINALIST FOR BEST NOVELLA Fix the past. Save the present. Stop the future. Master of science fiction Alastair Reynolds unfolds a time-traveling climate fiction adventure in Permafrost. 2080: at a remote site on the edge of the Arctic Circle, a group of scientists, engineers and physicians gather to gamble humanity’s future on one last-ditch experiment. Their goal: to make a tiny alteration to the past, averting a global catastrophe while at the same time leaving recorded history intact. To make the experiment work, they just need one last recruit: an ageing schoolteacher whose late mother was the foremost expert on the mathematics of paradox. 2028: a young woman goes into surgery for routine brain surgery. In the days following her operation, she begins to hear another voice in her head... an unwanted presence which seems to have a will, and a purpose, all of its own – one that will disrupt her life entirely. The only choice left to her is a simple one. Does she resist ... or become a collaborator?

Permafrost Hydrology systematically elucidates the roles of seasonally and perennially frozen ground on the distribution, storage and flow of water. Cold regions of the World are subject to mounting development which significantly affects the physical environment. Climate change, natural or human-induced, reinforces the impacts. Knowledge of surface and ground water processes operating in permafrost terrain is fundamental to planning, management and conservation. This book is an indispensable reference for libraries and researchers, an information source for practitioners, and a valuable text for training the next generations of cold region scientists and engineers.

"Permafrost es el sorprendente debut de Eva Baltasar, una historia contundente, íntima y carnal de una protagonista con pulsiones suicidas que se protege del exterior pero se entrega con intensidad al sexo con otras mujeres, la literatura y el arte. El permafrost es esa capa de la tierra permanentemente congelada y es también la membrana que cubre a la protagonista de esta novela. Escrita en primera persona, nos presenta a una mujer en etapa de formación que se protege del exterior, que percibe la superficialidad en todo cuanto la rodea y huye de un entorno que nada tiene que ver con su manera de entender la vida: una madre obsesionada con la salud, omnipresente y controladora, y una hermana que afronta su existencia convencional con medicación y un positivismo irritante. La protagonista, que siente pulsiones suicidas, no permite que nadie se le acerque demasiado, pero al mismo tiempo se entrega con intensidad al sexo con otras mujeres, la literatura y el arte. El pulso entre el hedonismo, los placeres más carnales y la muerte es constante en esta novela, así como el tono mordaz de una protagonista que nos gana con su inteligencia y su humor negrísimo desde la primera página. Repleto de imágenes poéticas, contundentes y muy físicas, este carácter tan palpable del texto no es gratuito en una novela que nos habla del cuerpo, del sexo, del yo; una obra aguda y directa que reivindica la libertad femenina en el placer y en la soledad. Eva Baltasar inicia con Permafrost un tríptico de protagonistas femeninas que quiere explorar distintas etapas en la vida de las mujeres"--

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.
