This book was released on 1999 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Landsat Thematic Mapper (TM) and Multispectral Scanner (MSS) imagery at two different spatial scales were employed during this research effort to provide two medium scale (1:63,360) vegetation maps of the Barrow Region on Alaska's North Slope. Detailed field sampling facilitated a site specific accuracy assessment of the digital classification to provide clues as to the reliability of each map. A comparison of the resultant map products was conducted to assess the effect of the resolution of satellite data on the investigator's ability to accurately interpret vegetation pattern in Arctic tundra. Accuracy assessment of the TM and MSS derived map products indicates that both types of remotely sensed imagery are limited in their ability to accurately represent specific vegetation types at the chosen map scale. The TM instrument, with its improvements in spatial, radiometric, and spectral resolution over the MSS sensor, produced a significantly more accurate vegetation map than that derived from the MSS data. It is concluded that the Landsat derived land cover maps prepared during this investigation provide information on the distribution of general vegetation types across the Barrow Region, but do not provide accurate site-specific vegetation data"--Leaf ii

Available in PDF, EPUB and Kindle. Book excerpt: Although wetlands cover over half of Alaska, the status, management and regulation of these areas is problematic. The technical literature on Alaskan wetland vegetation, soils and hydrology is abundant, but the application of the literature to wetland management is poorly developed. This report identifies problems, issues and information gaps in the management of Alaskan wetlands. There are numerous arguments and debates on the designation, function and values, and disturbance of certain wetlands in Alaska. Permafrost, fire cycles and unique hydrologic regimes complicate the designation and delineation of Alaskan wetlands. The functions and values of most Alaskan wetlands clearly lie in their importance as habitat, particularly for migrating waterbirds, but an understanding of their role in flood water storage, water quality improvement, subsistence and other functions remains controversial and in need of study. Disturbance and other impacts on Alaskan wetlands is small relative to the large area that wetlands cover and in comparison with the loss of wetlands in the lower 48 states. However, several development projects in Alaska have affected large wetland areas and methods to restore these wetlands are being developed. Cumulative impacts are unknown, as are techniques for restoring permafrost wetlands containing gravel fill.

Download or read book The Natural History of an Arctic Oil Field written by Joe C. Truett and published by Elsevier. This book was released on 2000-06-09 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of the harsh conditions that characterize the Arctic, it is a surprisingly fragile ecosystem. The exploration for oil in the Arctic over the past 30 years has had profound effects on the plants and animals that inhabit this frozen clime. The Natural History of an Arctic Oil Field synthesizes decades of research on these myriad impacts. Specialists with years of field experience have contributed to this volume to create the first widely available synopsis of the ecology and wildlife biology of animals and plants living in close association with an actively producing oil field. - First widely available synthesis of arctic oil field ecology and wildlife biology - Concise yet readable treatment of a diverse polar ecosystem - Useful for land managers, policy makers as well as ecologists, and population biologists - Chapters authored by recognized authorities and contributions are peer-reviewed for accuracy and scientific rigor - Illustrations attractively designed to enhance comprehension
Download or read book Cumulative Environmental Effects of Oil and Gas Activities on Alaska s North Slope written by National Research Council and published by National Academies Press. This book was released on 2003-09-04 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book identifies accumulated environmental, social and economic effects of oil and gas leasing, exploration, and production on Alaska's North Slope. Economic benefits to the region have been accompanied by effects of the roads, infrastructure and activies of oil and gas production on the terrain, plants, animals and peoples of the North Slope. While attempts by the oil industry and regulatory agencies have reduced many of the environmental effects, they have not been eliminated. The book makes recommendations for further environmental research related to environmental effects.
