Download or read book Macrofossil Pollen and Geochemical Records of Peatlands in the Kinosheo Lake and Detour Lake Areas Northern Ontario written by I. M. Kettles and published by . This book was released on 2000 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrofossil & pollen records from two cores in two lake peatlands in north-east Ontario cover over 4,000 years of vegetation history and record a succession of peatland environments. The cores were collected in research designed to study remote peat bogs as repositories of naturally occurring and anthropogenic metals. This report presents results of the first phase of that research, in which cores were collected through the peat sequence to mineral sediment and analyzed to gather baseline data on the geochemical & palaeoecological variations associated with different stages of peatland development. Micro- & macro-fossil data were integrated with geochronological data to establish vegetation assemblage successions from which past peatland environments were interpreted. The results also provide some information on the history of the boreal forest in the region of the two lakes.
Download or read book Peatlands written by I.P. Martini and published by Elsevier. This book was released on 2007-03-28 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two decades there has been considerable work on global climatic change and its effect on the ecosphere, as well as on local and global environmental changes triggered by human activities. From the tropics to the Arctic, peatlands have developed under various geological conditions, and they provide good records of global and local changes since the Late Pleistocene.The objectives of the book are to analyze topics such as geological evolution of major peatlands basins; peatlands as self sustaining ecosystems; chemical environment of peatlands: water and peat chemistry; peatlands as archives of environmental changes; influence of peatlands on atmosphere: circular complex interactions; remote sensing studies of peatlands; peatlands as a resource; peatlands degradation, restoration, plus more. * Presents an interdisciplinary approach, with an emphasis on Earth Science, and addresses the need for intergration between subdisciplines and the developing of new approaches* Synthesizes the evolutionary, ecological, and chemical characteristics of major peatlands, as well as focuses on the environmental changes, from climate changes to surface ares changes due to human activities* Covers topical studies of worldwide interest and provides examples from many different countries

Download or read book Peat and Peatland Resources of Northeastern Ontario written by John L. Riley and published by Sudbury, Ont. : Ontario Ministry of Northern Development and Mines. This book was released on 1994 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peatland resources of northeastern Ontario were investigated as part of the Peatland Inventory Project, conducted from 1982-85. Data from Hearst, Foleyet, Cochrane-Kapuskasing, Timmins-Kirkland Lake, and New Liskeard are presented and integrated to provide a regional overview of the resource. The methods used for the inventory ranged from on-site detailed mapping and sampling to regional satellite-imagery interpretation. Laboratory analyses on the physical and chemical properties of the peat were also undertaken for 698 samples. Of the 1,500 peatlands greater than 100 ha in size that were identified in the region, 128 were surveyed.
Download or read book Marine Isotope Stage 3 in Southern South America 60 KA B P 30 KA B P written by Germán Mariano Gasparini and published by Springer. This book was released on 2016-07-26 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents isotope data reflecting changes in temperature derived from core samples in South America. Marine Isotope Stage (MIS) is examined in detail with respect to Stage 3. With over 20 chapters, this detailed treatise discusses high climatic variability, paleoclimatic events, Dansgaard-Oeschger cycles, continental vertebrates, sea level changes, vegetation and climate changes based on pollen records, and the non-Amazon landscape and fauna from 65 to 20 ka B.P. The book also looks at the earth’s magnetic field and climate change during MIS 3 and MIS 5 and presents a comparison between both stages with respect to marine deposits in Uruguay. With case studies drawn from Brazil, Argentina and Uruguay this book presents research from the some of the worlds experts in this field.
Download or read book Canadian Inland Seas written by I.P. Martini and published by Elsevier. This book was released on 2011-09-22 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: The various chapters of this book have been written by researchers who are still working in the Canadian Inland Seas region. The chapters synthesize what is known about these seas, yet much still is to be learnt. It is hoped that this collection of information will serve as a springboard for future, much needed, studies in this fascinating, diverse region, and will stimulate comparative analyses with other subarctic and arctic basins of the world. The Canadian Inland Seas are the only remnants, albeit cold, of the ancient cratonic marine basins which occupied central North America throughout the Paleozoic and part of the Mesozoic. Precambrian rocks and gently dipping Paleozoic sedimentary rocks underlie the seas. The area is also close to the centers of Pleistocene glaciations. The coastal areas represent an emerged landscape of the post-glacial Tyrrell sea, as the region has been isostatically uplifted to about 350 meters since glacial times. A total of 56 fish species inhabit Hudson Bay and James Bay. Seals, whales and one of the largest and southernmost populations of polar bears inhabit the seas as well. The coastal areas are important habitats for migratory bird populations, some of which migrate from as far away as Southern Argentina. The ostic environment has preserved these regions relatively unchanged by man, with only a major harbour at Churchill, Manitoba, which is active for part of the year, and a second large, rail-terminal settlement in the south at Moosonee, Ontario. A few, small, native Indian and Inuit villages dot the coasts. The seas are being affected indirectly by the damming of rivers for the generation of hydroelectric power, and by drainage diversions towards the man-made reservoirs. A major project is being completed in Quebec east of James Bay, but other rivers in Ontario and Manitoba have been dammed as well. Undoubtedly freshwater is one of the more important resources of the area, however its exploitation needs careful thought because of the possible long-range effects on the environment, particularly the coastal marshes, which sustain much of the eastern American intercontinental migratory avifauna. Other resources occur in the regions, primarily minerals and perhaps petroleum. For the most part however, such resources remain to be discovered.
