Download or read book Influence of Climate Change on the Changing Arctic and Sub Arctic Conditions written by Jacques Nihoul and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current warming trends in the Arctic may shove the Arctic system into a seasonally ice-free state not seen for more than one million years. The melting is accelerating, and researchers were unable to identify natural processes that might slow the deicing of the Arctic. Such substantial additional melting of Arctic and Antarctic glaciers and ice sheets would raise the sea level worldwide, flooding the coastal areas where many of the world's population lives. Studies, led by scientists at the National Center for Atmospheric Research (NCAR) and the University of Arizona, show that greenhouse gas increases over the next century could warm the Arctic by 3-5°C in summertime. Thus, Arctic summers by 2100 may be as warm as they were nearly 130,000 years ago, when sea levels eventually rose up to 6 m higher than today.

Download or read book Biogeochemistry of the Atmosphere Ice and Water of the White Sea written by Alexander P. Lisitsyn and published by Springer. This book was released on 2019-02-01 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the biogeochemical environment of the White Sea, an inland sea in the Northwestern region of Russia. It provides a comprehensive review and discusses the latest research findings on the oceanology, sedimentology and biogeochemistry of the White Sea water column. The topics discussed include the regulation of the physico-geographical conditions in the White Sea basin; dispersed sedimentary substance of the atmosphere and the cryosphere; the geochemical peculiarities of the river discharge into the White Sea; and the phyto- and zooplankton activities in the White Sea. Taking the biggest river in the White Sea basin as an example, the authors closely examine the deposition of suspended particulate matter, the biogeochemical behaviour of dissolved and suspended forms of organic material and the significant group of chemical elements in the river-sea mixing zone of the Severnaya Dvina River. The book ends with a summary of the key conclusions and recommendations. Together with the companion volume Sedimentation Processes in the White Sea: The White Sea Environment Part II, it offers an essential source of information for postgraduate students, researchers and stakeholders alike.
Download or read book Ancient Harp Seal Hunters of Disko Bay written by Morten Meldgaard and published by Museum Tusculanum Press. This book was released on 2004 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Saqqaq Culture site Qeqertasussuk (2400-1400 BC) is situated in the south eastern corner of Disko Bay, West Greenland. The site was excavated between 1983 and 1987 by Qasigiannguit Museum. The stratified cultural deposits are exceptionally well preserved by permafrost and yielded hundreds of thousands of animal bones, feathers, plant remains, insect remains, wooden implements, and a wealth of other organic refuse as well as stone tools, house ruins, stone set fireplaces and other traces of habitation. In order to understand the life conditions of the inhabitants at Qeqertasussuk, a comparative survey of the historic distribution, density and availability of the living resources in the area is undertaken. This resource model is then evaluated against the paleo-environmental data. Also, comparative ethnohistorical and ethnographic data on the exploitation of the living resources in the area is presented. Subsistence and subsistence change at Qeqertasussuk is studied through a comprehensive analysis of the faunal material that consists of more than 200,000 animal bones. Quantitative methods are supplemented by detailed studies of seasonality and age composition of the hunting bag. Forty three species of animals are represented. Harp seal and ringed seal represent the most important game, but sea birds such as fulmar, Brünnich's guillemot, and little auk also play a significant role in the subsistence economy. Fish, especially Atlantic Cod, have been caught and remains of large whales indicate that these animals were utilized, but it can not be decided whether they were actively hunted. Most of the game was taken close by the site, however finds of caribou indicate that inland caribou hunting was undertaken and that Qeqertasussuk was part of a larger subsistence-settlement-system. Several species of plants were also utilized. Temporal changes in the composition of the faunal material indicate that significant changes occur in the subsistence at Qeqertasusuk. Four phases are identified: (1) Basecamp period I (2400-2100 BC). A pioneer phase where the site is used as a year-round base camp with more than 90% of the biomass being harvested within an area of approximately 80 km2, (2) Base-camp period II (2100-1900 BC), which seems to be the period of most intensive use and where new methods (probably netting) of harp seal hunting are introduced, (3) Hunting camp period (1900-1700 BC), where the site becomes more specialized and more seasonal with a focus on spring-summer hunting for harp seals, (4) high activity period (1700-1400 BC) indications of continued heavy sea mammal hunting. The site was abandoned around 1400 BC. The causes of the abandonment of Qeqertasussuk is discussed and the impact of the general cooling around 1500 BC on key resources such as harp seal and capelin is highlighted.
Download or read book The Arctic Seas written by Yvonne Herman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 887 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic region has long held a fascination for explorers and scientists of many countries. Despite the numerous voyages of exploration, the na ture of the central Arctic was unknown only 90 years ago; it was believed to be a shallow sea dotted with islands. During Nansen's historic voyage on the polarship Fram, which commenced in 1893, the great depth of the central basin was discovered. In the Soviet Union, investigation of the Arctic Ocean became national policy after 1917. Today research at several scientific institutions there is devoted primarily to the study of the North Polar Ocean and seas. The systematic exploration of the Arctic by the United States com menced in 1951. Research has been conducted year-round from drifting ice islands, which are tabular fragments of glacier ice that break away from ice shelves. Most frequently, ice islands originate off the northern coast of Ellesmere Island. These research platforms are occupied as weather sta tions, as well as for oceanographic and geophysical studies. Several inter national projects, conducted by Canadian, European, and U. S. groups, have been underway during the last three decades. Although much new data have accumulated since the publication of the Marine Geology and Oceanography of the Arctic Seas volume in 1974 (Yvonne Herman, ed. ), in various fields of polar research-including present-day ice cover, hydrogra phy, fauna, flora, and geology-many questions remain to be answered.
