Available in PDF, EPUB and Kindle. Book excerpt: Not only were more African slaves transported to South America than to North, but overlapping imperialisms and shared resistance to them have linked Africa, Latin America, and the Caribbean for over five centuries. Yet despite the rise in transatlantic, oceanic, hemispheric, and regional studies, and even the growing interest in South-South connections, the South Atlantic has not yet emerged as a site that captures the attention it deserves. The Global South Atlantic traces literary exchanges and interlaced networks of communication and investment—financial, political, socio-cultural, libidinal—across and around the southern ocean. Bringing together scholars working in a range of languages, from Spanish to Arabic, the book shows the range of ways people, governments, political movements, social imaginaries, cultural artefacts, goods, and markets cross the South Atlantic, or sometimes fail to cross. As a region made up of multiple intersecting regions, and as a vision made up of complementary and competing visions, the South Atlantic can only be understood comparatively. Exploring the Atlantic as an effect of structures of power and knowledge that issue from the Global South as much as from Europe and North America, The Global South Atlantic helps to rebalance global literary studies by making visible a multi-textured South Atlantic system that is neither singular nor stable.
Download or read book The South Atlantic written by Gerold Wefer and published by Springer. This book was released on 1996-12-17 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents results of recent projects in oceanography and marine geosciences (e.g. WOCE, JGOFS, PAGES, ODP) regarding present and past circulation in the South Atlantic. The objective of the book is to integrate results from both oceanographic and geological studies. As the connecting link between the Antarctic and the North Atlantic, the South Atlantic plays a crucial role with regard to the heat budget of the North Atlantic and to the biogeochemical budget of the global ocean. New results from studies of meridional water mass and heat transports are presented. The central theme of geological investigations is the reconstruction of current and productivity systems in the South Atlantic during the late Quaternary.

This book was released on 2012-12-06 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: The South Atlantic plays a critical role in the couplingofoceanic processes between the Antarctic and the lower latitudes. The Antarctic Ocean, along with the adjacent southern seas, is of substantial importance for global climate and for the distributionofwater masses because itprovides large regions ofthe world ocean with intermediate and bottom waters. In contrast to the North Atlantic, the Southern Ocean acts more as an "information distributor", as opposed to an amplifier. Just as the North Atlantic is influencedby the South Atlantic through the contributionofwarm surface water,the incomingsupply ofNADW - in the area of the Southern Ocean as Circumantarctic Deep Water - influences the oceanography ofthe Antarctic. The competing influences from the northern and southern oceans on the current and mass budget systems can be best studied in the South Atlantic. Not only do changes in the current systems in the eastern Atlantic high-production regions affect the energy budget, they also influence the nutrient inventories, and therefore impact the entire productivity ofthe ocean. In addition, the broad region of the polar front is a critical area with respect to productivity-related circulation since it is the source of Antarctic Intermediate Water. Although theAntarctic Intermediate Watertoday liesdeeper than the water that rises in the upwelling regions, it is the long-term source ofnutrients that are ultimately responsible for the supply oforganic matter to the sea floor and to sediments.

Book excerpt: Everyone working in a problem as complex as continental drift, must at some time have feit the need for an objective data summary in fields other than his own. It is a scientific dilemma that, aIthough there is evident need for researchers with competence in many fields (the classical natural scientist), the time in volved in acquiring such broad experience is so great as to ren der the task largely impossible. The alternative seems to be the team approach, and we have espoused it in tbis volume. Editors and contributors alike have tried in this book to keep the accent upon factual information and to reduce interpretation to a minimum. Interpretation there must be, however, since without it science is but an inteHectual pastime comparable to pbilately. The librarian's need to classify results in the appearance of our names upon the spine oftbis volume, however, we would like to make it clear that the book has been a truly cooperative effort and could not have succeeded but for the active help of the individual contributors, whose assistance seldom was re stricted to their chapters. Special thanks must be given to our South American coHeagues, for the tolerance with which they viewed out editorial attempts, and to Dr. E. Machens, for his careful review of the translation of his manu script. We wish also to acknowledge the help of Dr. C. W.
Download or read book The South Atlantic in the Late Quaternary written by Gerold Wefer and published by . This book was released on 2004-04-13 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: The South Atlantic plays a significant role as a link between the Antarctic Ocean and the North Atlantic, both in terms of the heat budget of the North Atlantic and the circulation of the entire ocean. The heat and mass exchanges between the Antarctic Ocean and the South Atlantic during the Late Quaternary have been investigated over the past ten years, including their impact on world climate. This has required the study of present-day early diagenetic processes in the water column and sediments, as well as sediment properties that have a close relationship to environmental parameters ("proxies"), which can be used to decipher past conditions (temperature, salinity, productivity, etc.). The interdisciplinary research project "The South Atlantic in the Late Quaternary - Reconstruction of material budgets and current systems" was a long-term scientific program at Bremen University. This program benefited from the sample material gained on several expeditions with the research vessels Meteor and Polarstern. This book presents the summarized results of the various topics of study in 30 articles arranged in seven sections.

Download or read book Use of Proxies in Paleoceanography written by Gerhard Fischer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleoceanographic proxies provide infonnation for reconstructions of the past, including climate changes, global and regional oceanography, and the cycles of biochemical components in the ocean. These prox ies are measurable descriptors for desired but unobservable environmental variables such as tempera ture, salinity, primary productivity, nutrient content, or surface-water carbon dioxide concentrations. The proxies are employed in a manner analogous to oceanographic methods. The water masses are first characterized according to their specific physical and chemical properties, and then related to particular assemblages of certain organisms or to particular element or isotope distributions. We have a long-standing series of proven proxies available. Marine microfossil assemblages, for instance, are employed to reconstruct surface-water temperatures. The calcareous shells of planktonic and benthic microorgan isms contain a wealth of paleoceanographic information in their isotopic and elemental compositions. Stable oxygen isotope measurements are used to detennine ice volume, and MglCa ratios are related to water temperatures, to cite a few examples. Organic material may also provide valuable infonnation, e. g. , about past productivity conditions. Studying the stable carbon isotope composition of bulk organic matter or individual marine organic components may provide a measure of past surface-water CO 2 conditions within the bounds of certain assumptions. Within the scope of paleoceanographic investigations, the existing proxies are continuously evolving and improving, while new proxies are being studied and developed. The methodology is improved by analysis of samples from the water column and surface sediments, and through laboratory experiments.
