Book Description
This book provides a comprehensive, up-to-date assessment of the key terrestrial components of the Arctic system, i.e., its hydrology, permafrost, and ecology, drawing on the latest research results from across the circumpolar regions. The Arctic is an integrated system, the elements of which are closely linked by the atmosphere, ocean, and land. Using an integrated system approach, the book’s 30 chapters, written by a diverse team of leading scholars, carefully examine Arctic climate variability/change, large river hydrology, lakes and wetlands, snow cover and ice processes, permafrost characteristics, vegetation/landscape changes, and the future trajectory of Arctic system evolution. The discussions cover the fundamental features of and processes in the Arctic system, with a special focus on critical knowledge gaps, i.e., the interactions and feedbacks between water, permafrost, and ecosystem, such as snow pack and permafrost changes and their impacts on basin hydrology and ecology, river flow, geochemistry, and energy fluxes to the Arctic Ocean, and the structure and function of the Arctic ecosystem in response to past/future changes in climate, hydrology, and permafrost conditions. Given its scope, the book offers a valuable resource for researchers, graduate students, environmentalists, managers, and administrators who are concerned with the northern environment and resources.

Book Description
In the late 18th century explorers and scientists started venturing into the Arctic in a heroic and sometimes deadly effort to understand and unveil the secrets of the unforgiving and mysterious polar region of the high north. Despite that the Arctic was already populated mattered less for the first wave of polar researchers and explorations who nevertheless, brought back valuable knowledge. Today the focus in Arctic science and discourse has changed to one which includes the peoples and societies, and their interaction with the world beyond. The image of a static Arctic - heralded first by explorers - prevailed for a long time, but today the eyes of the World see the Arctic very differently. Few, if any, other places on Earth are currently experiencing the kind of dramatic change witnessed in the Arctic. According to model forecasts, these changes are likely to have profound implications on biophysical and human systems, and will accelerate in the decades to come. “The New Arctic” highlights how, and in what parts, the natural and political system is being transformed. We’re talking about a region where demography, culture, and political and economic systems are increasingly diverse, although many common interests and aspects remain; and with the new Arctic now firmly placed in a global context. Settlements range from small, predominantly indigenous communities, to large industrial cities, and all have a link to the surrounding environment, be it glaciers or vegetation or the ocean itself. “The New Arctic” contributes to our further understanding of the changing Arctic. It offers a range of perspectives, which reflect the deep insight of a variety of scientific scholars across many disciplines bringing a wide range of expertise. The book speaks to a broad audience, including policy-makers, students and scientific colleagues.

Book Description
Marine and freshwater polar environments are characterized by intense physical forces and strong seasonal variations. The persistent cold and sometimes inhospitable conditions create unique ecosystems and habitats for microbial life. Polar microbial communities are diverse productive assemblages, which drive biogeochemical cycles and support higher food-webs across the Arctic and over much of the Antarctic. Recent studies on the biogeography of microbial species have revealed phylogenetically diverse polar ecotypes, suggesting adaptation to seasonal darkness, sea-ice coverage and high summer irradiance. Because of the diversity of habitats related to atmospheric and oceanic circulation, and the formation and melting of ice, high latitude oceans and lakes are ideal environments to investigate composition and functionality of microbial communities. In addition, polar regions are responding more dramatically to climate change compared to temperate environments and there is an urgent need to identify sensitive indicators of ecosystem history, that may be sentinels for change or adaptation. For instance, Antarctic lakes provide useful model systems to study microbial evolution and climate history. Hence, it becomes essential and timely to better understand factors controlling the microbes, and how, in turn, they may affect the functioning of these fragile ecosystems. Polar microbiology is an expanding field of research with exciting possibilities to provide new insights into microbial ecology and evolution. With this Research Topic we seek to bring together polar microbiologists studying different aquatic systems and components of the microbial food web, to stimulate discussion and reflect on these sensitive environments in a changing world perspective.

Book Description
extreme weather will mean ongoing challenges to the capacity of these sectors to support human well-being, grow the economy, and provide critical environmental services. Society has yet to evaluate the resilience of FEWS to climate, environmental, and management stresses as it shapes strategies to support sustainable development over the next decades. These issues constitute a quintessential interdisciplinary research challenge and require a well-structured science agenda and supportive information services for implementing key findings that governments and stakeholders can adopt. Integrated policy pathways require usable research findings, applications, models, real-time information systems, and decision support systems. In addition, stakeholder engagement is essential to communicate the benefits and results of these approaches and to engage appropriate groups in their implementation.

Book Description
Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.
