Book excerpt: 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.

Book Synopsis Once Upon the Permafrost by : Susan Alexandra Crate

Download or read book Once Upon the Permafrost written by Susan Alexandra Crate. This book was released on 2021-11-30. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis The Big Thaw by : Eric Scigliano

Download or read book The Big Thaw written by Eric Scigliano. This book was released on 2019. Available in PDF, EPUB and Kindle. Book excerpt: Permafrost--dark, ice-flaked, permanently frozen ground that lies under tundra and boreal forests across our northern regions--covers more than 12 percent of the earth's land mass. It exists in places that seem otherworldly and unimaginably remote to most of us, but the changes taking place in the permafrost layer may ultimately affect the lives of every person on Earth. InThe Big Thaw, readers meet a diverse team of scientists and students who have been studying the permafrost and what lies beneath: a vast store of ancient carbon, more than four times the quantity found in all of today's forests, which is releasing carbon dioxide and methane as the permafrost melts. The release of all this carbon would alter Earth's climate forever. Braving endless hordes of mosquitoes, quicksand, and extreme temperatures, the researchers are racing against the clock to educate us all about the changes we must make in order to preserve Earth's carbon balance.

Download or read book Understanding and Responding to Global Health Security Risks from Microbial Threats in the Arctic written by European Academies Science Advisory Council. This book was released on 2020-10-30. Available in PDF, EPUB and Kindle. Book excerpt: The National Academies of Sciences, Engineering, and Medicine in collaboration with the InterAcademy Partnership and the European Academies Science Advisory Committee held a workshop in November 2019 to bring together researchers and public health officials from different countries and across several relevant disciplines to explore what is known, and what critical knowledge gaps remain, regarding existing and possible future risks of harmful infectious agents emerging from thawing permafrost and melting ice in the Arctic region. The workshop examined case studies such as the specific case of Arctic region anthrax outbreaks, as a known, observed risk as well as other types of human and animal microbial health risks that have been discovered in snow, ice, or permafrost environments, or that could conceivably exist. The workshop primarily addressed two sources of emerging infectious diseases in the arctic: (1) new diseases likely to emerge in the Arctic as a result of climate change (such as vector-borne diseases) and (2) ancient and endemic diseases likely to emerge in the Arctic specifically as a result of permafrost thaw. Participants also considered key research that could advance knowledge including critical tools for improving observations, and surveillance to advance understanding of these risks, and to facilitate and implement effective early warning systems. Lessons learned from efforts to address emerging or re-emerging microbial threats elsewhere in the world were also discussed. This publication summarizes the presentation and discussion of the workshop.
