Sedimentation History In The Arctic Ocean And Subarctic Seas For The Last 130 Kyr

The book reflects the results of the study of sedimentation history, paleoclimatology, and paleoceanography of the Arctic and Subarctic during the last 130 ka. The main objects under consideration are marine basins of the West Subarctic (Iceland, Norwegian, and Greenland Seas), the Arctic Ocean (Barents, Pechora, Kara, Laptev, East Siberian, Chukchi Seas and deep-sea Arctic Ocean proper), East Subarctic (Bering and Okhotsk Seas). The modern environment and geological history of water- (ice-) sheds and marine basins have been studied for each region, using different sedimentological and geochemical proxies. Mainly results of the authors' own studies are represented, with special emphasis on glacial/interglacial variability and land-ocean interaction. The book is aimed at sedimentologists, quaternary and marine geologists, paleoclimatologists and paleoceanographers, as well as being of great interest to students in the related fields.

This book presents 41 selected articles written by leading researchers from the Vernadsky Institute of Geochemistry and Analytical Chemistry, part of the Russian Academy of Sciences. The articles are grouped by the following topics: (1) Geochemistry, (2) Meteoritics, Cosmochemistry, Lunar and Planetary Sciences, (3) Biogeochemistry and Ecology, and (4) Analytical Chemistry, Radiochemistry, and Radioecology. The articles present recent experimental data, theoretical investigations, critical reviews, the results of computer modeling in the above-mentioned fields. Intended to provide a scientific “snapshot” of the institute, the book also includes content on its history, main scientific achievements and current goals, together with detailed descriptions of its 25 laboratories and three museums so as to promote new international collaborations. Given its scope, the book will be of interest to all scientists and graduate students working in the areas of geochemistry, analytical chemistry and radiochemistry, earth and environmental sciences, biogeosciences, meteoritics and planetary science, and to those seeking new collaboration opportunities in these areas in Russia.

Throughout history cities have been locations of human encounter. Equally they have been contexts for the trade of goods and services, for the evolution of various forms of urban space, and for the production, development, and enrichment of culture and technology. Many cities grew up along shorelines, which themselves constitute some of the globe’s most important cultural boundaries. For above all else, it is water that has separated but also connected different communities, races, religions and nations, down through recorded time. With the rapid advance in technologies of communication, encounters between cultures have multiplied at a rate that no individual can follow or control. The present book constitutes a space of “memory” in its own right, one of its chief raisons d’être being that a group of diverse scholars herein maps certain key encounters between peoples, past as well as present, and the urgent issues generated in consequence. No one person could have traced such diversity and made sense of it, whereas a scholarly grouping of persons reporting on phenomena from around the world, such as is provided here, offers its readers a vision of global change and development. With the twentieth and twenty-first centuries a new set of mega-cities in Asia, Africa, and Latin America has emerged to challenge the primacy of European and North American metropolitan centres. This expanded landscape is here interpreted with special attention, as already mentioned, to cities located at coastlines, hence (generally speaking) more exposed to globalizing trends. Migrants, exiles and refugees, ethnic and racial minorities, as well as alternative or countercultural groupings continue to complicate the ways in which cities articulate their now pluralized identities, in terms of (and by means of) literature, history, architecture, social events, and other forms of artistic and cultural production. The international scholars whose work is assembled in these pages are well placed to engage with the intersecting themes and issues of the volume. Contributors have mapped different examples from Homeric narrative, through Renaissance drama and its representation of crossways of culture such as Rhodes and Malta, to an earlier time in the development of a New World city such as Boston: others look at the twentieth and twenty-first centuries’ complexity of great world cities and of oceanic migration or trade between them. Shanghai, Singapore, London, Detroit, Shantou, Macau, and Saigon are some that are dealt with in detail. Emphasis falls on both the historical reality of those contexts as well as how they have been culturally represented.

Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-through in Arctic research, were carried out into the central Artic and its surrounding shelf seas. Results from these expeditions have greatly advanced our knowledge on Arctic Ocean paleoenvironments. Published syntheses about the knowledge on Arctic Ocean geology, on the other hand, are based on data available prior to 1990. A comprehensive compilation of data on Arctic Ocean paleoenvironment and its short-and long-term variability based on the huge amount of new data including the ACEX drilling data, has not been available yet. With this book, presenting (1) detailed information on glacio-marine sedimentary processes and geological proxies used for paleoenvironmental reconstructions, and (2) detailed geological data on modern environments, Quaternary variability on different time scales as well as the long-term climate history during Mesozoic-Tertiary times, this gap in knowledge will be filled. *Aimed at specialists and graduates *Presents background research, recent developments, and future trends *Written by a leading scholar and industry expert

This reference book for researchers working on glacial sediments provides a complete overview of the various glacial deposits in the ocean. It presents a collection of worldwide data on glacio-marine phenomena.
