Download or read book Arctic Ice Shelves and Ice Islands written by Luke Copland and published by Springer. This book was released on 2017-05-30 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the current state of knowledge of Arctic ice shelves, ice islands and related features. Ice shelves are permanent areas of ice which float on the ocean surface while attached to the coast, and typically occur in very cold environments where perennial sea ice builds up to great thickness, and/or where glaciers flow off the land and are preserved on the ocean surface. These landscape features are relatively poorly studied in the Arctic, yet they are potentially highly sensitive indicators of climate change because they respond to changes in atmospheric, oceanic and glaciological conditions. Recent fracturing and breakup events of ice shelves in the Canadian High Arctic have attracted significant scientific and public attention, and produced large ice islands which may pose a risk to Arctic shipping and offshore infrastructure. Much has been published about Antarctic ice shelves, but to date there has not been a dedicated book about Arctic ice shelves or ice islands. This book fills that gap.

Download or read book Arctic Shorebirds in North America written by Jonathan Robert Bart and published by Univ of California Press. This book was released on 2012-09-01 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year shorebirds from North and South America migrate thousands of miles to spend the summer in the Arctic. There they feed in shoreline marshes and estuaries along some of the most productive and pristine coasts anywhere. With so much available food they are able to reproduce almost explosively; and as winter approaches, they retreat south along with their offspring, to return to the Arctic the following spring. This remarkable pattern of movement and activity has been the object of intensive study by an international team of ornithologists who have spent a decade counting, surveying, and observing these shorebirds. In this important synthetic work, they address multiple questions about these migratory bird populations. How many birds occupy Arctic ecosystems each summer? How long do visiting shorebirds linger before heading south? How fecund are these birds? Where exactly do they migrate and where exactly do they return? Are their populations growing or shrinking? The results of this study are crucial for better understanding how environmental policies will influence Arctic habitats as well as the far-ranging winter habitats used by migratory shorebirds.

Download or read book The Oxford Handbook of Light in Archaeology written by Costas Papadopoulos and published by Oxford University Press. This book was released on 2021-12-09 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light has a fundamental role to play in our perception of the world. Natural or artificial lightscapes orchestrate uses and experiences of space and, in turn, influence how people construct and negotiate their identities, form social relationships, and attribute meaning to (im)material practices. Archaeological practice seeks to analyse the material culture of past societies by examining the interaction between people, things, and spaces. As light is a crucial factor that mediates these relationships, understanding its principles and addressing illumination's impact on sensory experience and perception should be a fundamental pursuit in archaeology. However, in archaeological reasoning, studies of lightscapes have remained largely neglected and understudied. This volume provides a comprehensive and accessible consideration of light in archaeology and beyond by including dedicated and fully illustrated chapters covering diverse aspects of illumination in different spatial and temporal contexts, from prehistory to the present. Written by leading international scholars, it interrogates the qualities and affordances of light in different contexts and (im)material environments, explores its manipulation, and problematises its elusive properties. The result is a synthesis of invaluable insights into sensory experience and perception, demonstrating illumination's vital impact on social, cultural, and artistic contexts.
Download or read book Studying Arctic Fields written by Ricard C. Powell and published by McGill-Queen's Press - MQUP. This book was released on 2017-12-12 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the circumpolar region has emerged as the key to understanding global climate change. The plight of the polar bear, resource extraction debates, indigenous self-determination, and competing definitions of sovereignty among Arctic nation-states have brought the northernmost part of the planet to the forefront of public consideration. Yet little is reported about the social world of environmental scientists in the Arctic. What happens at the isolated sites where experts seek to answer the most pressing questions facing the future of humanity? Portraying the social lives of scientists at Resolute in Nunavut and their interactions with logistical staff and Inuit, Richard Powell demonstrates that the scientific community is structured along power differentials in response to gender, class, and race. To explain these social dynamics the author examines the history and vision of the Government of Canada’s Polar Continental Shelf Program and John Diefenbaker’s “Northern Vision,” combining ethnography with wider discourses on nationalism, identity, and the postwar evolution of scientific sovereignty in the high Arctic. By revealing an expanded understanding of the scientific life as it relates to politics, history, and cultures, Studying Arctic Fields articulates a new theory of field research. Advocating for a greater appreciation of science in the remote parts of the world, Studying Arctic Fields is an innovative approach to anthropology, environmental inquiry, and geography, and a landmark statement on Arctic science as a social practice.

Download or read book Effects of Climate Variation on the Breeding Ecology of Arctic Shorebirds written by Hans Meltofte and published by Museum Tusculanum Press. This book was released on 2007 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 50 species of shorebirds breed in the Arctic, where they constitute the most characteristic component of the tundra avifauna. Here, we review the impact of weather and climate on the breeding cycle of shorebirds based on extensive studies conducted across the Arctic. Conditions for breeding shorebirds are highly variable among species, sites and regions, both within and between continents. Weather effects on breeding are most moderate in the Low Arctic of northern Europe and most extreme in the Siberian High Arctic. The decision of whether or not to breed upon arrival on the breeding grounds, the timing of egg-laying and the chick-growth period are most affected by annual variation in weather. In large parts of the Arctic, clutch initiation dates are highly correlated with snowmelt dates and in regions and years where extensive snowmelt occurs before or soon after the arrival of shorebirds, the decision to breed and on the breeding ecology of clutch initiation dates appear to be a function of food availability for laying females. Once incubation is initiated, adult shorebirds appear fairly resilient to variations in temperature with nest abandonment primarily occurring in case of severe weather with new snow covering the ground. Feeding conditions for chicks, a factor highly influenced by weather, affects juvenile production in most regions. Predation has a very strong impact on breeding productivity throughout the Arctic and subarctic, with lemming Dicrostonyx spp. and Lemmus spp. fluctuations strongly influencing predation rates, particularly in the Siberian Arctic. The fate of Arctic shorebirds under projected future climate scenarios is uncertain, but High Arctic species and populations appear particularly at risk. Climatic amelioration may benefit Arctic shorebirds in the short term by increasing both survival and productivity, whereas in the long term habitat changes both on the breeding grounds and on the temperate and tropical non-breeding areas may put them under considerable pressure and may bring some of them near to extinction. Their relatively low genetic diversity, which is thought to be a consequence of survival through past climatically-driven population bottlenecks, may also put them more at risk to anthropogenic-induced climate variation than other avian taxa.
