Book Synopsis Global Palaeoclimate of the Late Cenozoic by : V.A. Zubakov
Download or read book Global Palaeoclimate of the Late Cenozoic written by V.A. Zubakov. This book was released on 1990-03-20. Available in PDF, EPUB and Kindle. Book excerpt: This is a detailed description of the history and chronology of global climate based on event-signal stratigraphy. The history of global climate is described for the last fifty million years with the description for the last one million years in detail. Climatostratigraphic sequences of twelve key regions are taken as a basis, eight of them situated in the USSR territories. Chronology of climatic events of the Pleistocene, Pliocene and Miocene is developed based on palaeomagnetic and radiometric data. The authors' version of its correlation with oxygene-isotope scales of deep-sea sediments is given. Theoretical problems of climatic stratigraphy and palaeoclimatology are discussed, in particular, the causes of climatic change. The Northern Hemisphere palaeoclimatic reconstructions are made for the Holocene, Eemian and Pliocene temperature optima, considered as possible palaeoanalogues of climate of the 21st Century. The book is intended primarily for a wide circle of scientific workers, palaeoclimatologists and palaeogeographers, but will also interest geologists, biologists, palaeomagnetologists and archaeologists.

Book Synopsis The Arctic Seas by : Yvonne Herman
Download or read book The Arctic Seas written by Yvonne Herman. This book was released on 2012-12-06. 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.

Book Synopsis Arctic and Environmental Change by : J.A. Dowdeswell
Download or read book Arctic and Environmental Change written by J.A. Dowdeswell. This book was released on 2019-09-17. Available in PDF, EPUB and Kindle. Book excerpt: This timely book presents a wide-ranging review of Arctic environmental change in response to global warming, and gives a broad insight into the transformation of the Arctic which we can expect during the next century. It is in high northern latitudes that we can expect to observe global warming at its most powerful, making it a natural laboratory where climate changes and their impacts can be monitored and studied more readily than elsewhere in the world. Fourteen authoritative reviews cover the predictions of warming rates by General Circulation Models; variabilities in atmospheric circulation and moisture flux; the dynamics of the polar vortex in the Arctic and its role in ozone loss; the countervailing influence of air pollution in reducing solar irradiance; and the impact of climatic change on Arctic terrestrial and marine ecosystems. Also detailed are the thermohaline circulation of the ocean, the extent and thickness of sea ice, the sizes of glaciers and ice sheets, and the extent of permafrost. Moving to past changes, the records from Greenland ice cores and deep ocean drilling are reviewed for what they tell us about past climates and glaciation in the Arctic., The book paints a vivid and disturbing picture of the enhanced warming that can be expected in the Arctic relative to lower latitudes, and of the major impacts that this will have on the northern cryosphere. It will be an invaluable reference for anyone seeking a greater understanding of the factors and processes affecting the arctic environment, which may ultimately have a major impact on global climatic change.
