Download or read book Responding to Oil Spills in the U S Arctic Marine Environment written by National Research Council and published by National Academies Press. This book was released on 2014-08-01 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.

Download or read book Polar Bears written by IUCN/SSC Polar Bear Specialist Group. Working Meeting and published by IUCN. This book was released on 2006 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings provide an overview of the ongoing research and management activities on polar bears in the circumpolar arctic. Together with the previous 13 proceedings, they provide an historic record of international efforts in protecting, studying and managing polar bears. With recent documentation of how warmer arctic climate might affect the sea ice habitat of polar bears, the predictions of even warmer climate in the next decades, and documentation of effects on polar bears subpopulations, an evaluation of the red list status of polar bear subpopulations was followed by an increased conservation designation of vulnerable. In the complexity of possible interactions between climate change, local harvest, and in some areas high levels of pollutants, an increased level of international cooperation was advocated.

Download or read book Climate Change in Eurasian Arctic Shelf Seas written by Ivan E. Frolov and published by Springer Science & Business Media. This book was released on 2010-01-10 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the eminent authors analyse the ice cover variability in the Arctic Seas during the 20th and early 21st centuries. In the first two chapters, they show that multi-year changes of the sea-ice extent in the Arctic Seas were formed by linear trends and long-term (climatic) cycles lasting about 10, 20 and 60 years. The structure of temporal variability of the western region (Greenland – Kara) differs significantly from the eastern region seas (Laptev and Chukchi). In the latter region, unlike the former area, relatively short-period cycles (up to 10 years) predominate. The linear trends can be related to a super-secular cycle of climatic changes over about 200 years. The most significant of these cycles, lasting 60 years, is most pronounced in the western region seas.

Download or read book Elephant Seals written by Burney J. Le Beouf and published by Univ of California Press. This book was released on 2023-11-10 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The largest of all seals, elephant seals rank among the most impressive of marine mammals. They are renowned for their spectacular recovery from near-extinction at the end of the nineteenth century when seal hunters nearly eliminated the entire northern species. No other vertebrate has come so close to extinction and made such a complete recovery. The physiological extremes that elephant seals can tolerate are also remarkable: females fast for a month while lactating, and the largest breeding males fast for over one hundred days during the breeding seasons, at which times both sexes lose forty percent of their body weight. Elephant seals dive constantly during their long foraging migrations, spending more time under water than most whales and diving deeper and longer than any other marine mammal. This first book-length discussion of elephant seals brings together worldwide expertise from scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals. Essential for all marine mammalogists for its information and its methodological innovations, Elephant Seals will also illuminate current debates about species extinctions and possible means of preventing them.

This book was released on 2011-03-23 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: “The bones recovered from the middens of the northeastern Pacific shorelines have important stories to tell biologists, marine mammalogists, and those concerned with marine conservation. This volume unearths a wealth of information about the historical ecology of seals, sea lions, and sea otters in the North Pacific that spans thousands of years. It provides fascinating insights into how the world once looked, and how it may one day look again as seals, sea lions, and sea otters reclaim and recolonize their former haunts.”—Andrew Trites, Director, Marine Mammal Research Unit, University of British Columbia “Braje and Rick have assembled a compelling set of case studies on the long-term and complex interactions between people, marine mammals, and environments in the Northeast Pacific. The promise of zooarchaeology as historical science is on full display, as researchers use geochemistry, aDNA, morphometrics, and traditional analytic methods to address questions of utmost importance to the long-term health of coastal ecosystems. If this book doesn't convince conservation biology about the need to take the long view of animal histories and ecosystems into account in developing conservation management plans, I'm not sure what will.”—Virginia L. Butler, Department of Anthropology, Portland State University
