Book Description
The era of the exploration of the World Ocean is not yet over: some areas still lack an adequate number of observations. The relationships between the physical, chemical and biological processes, which sustain the life on this planet, are not yet fully understood. In short, knowledge of the oceans is still far from satisfactory. This book covers an important period in the study of one of the last investigated areas of the World Ocean: the Ross Sea, Antarctica. During the 1990s, long-term experiments were conducted in this area as part of the Climatic Long-term Interaction for the Mass balance in Antarctica (CLIMA) project of the Italian National Programme for Antarctic Research (PNRA), providing a wealth of oceanographic information. This book is an outcome of the CLIMA field obser vations and international collaborations with the most important programmes in the Ross Sea-Southern Ocean area. It contributes to the st!ldies of the spatial and temporal variability of Ross Sea water masses and circulation and their relation ship with the Southern Ocean circulation. A comprehensive review of historical data is offered, and new data sets are analysed. The studies presented in this book show that much progress has been achieved during the last decade, but large gaps in our understanding of the physical processes in the Ross Sea are still to be filled. However, these studies contribute significantly to the investigation of some specific aspects regarding the circula tion of the main water masses.
Ross Sea Ecology

ISBN: 364259607X
Category : Science
Languages : en
Pages : 594
Book Description
The Antarctic represents the last of the world's still unexplored continents. Since 1985, Italy has sent 10 expeditions to this region, three of those have been exclusively devoted to research on the marine ecology of the Ross Sea region. This volume presents a global picture of this research. It includes contributions on water mass characteristics, particulate organic matter and nutrient utilization, and physiological aspects of primary production. Further topics are zooplankton, krill and top predator interactions in relation to physical and biological parameters, ecological features of coastal fish communities and the spatio-temporal variability of benthic biocenoses.
The Silicon Cycle
Author: Venugopalan IttekkotPublisher: Island Press
ISBN: 1597267821
Category : Science
Languages : en
Pages : 297
Book Description
Silicon is among the most abundant elements on earth. It plays a key but largely unappreciated role in many biogeochemical processes, including those that regulate climate and undergird marine food webs. The Silicon Cycle is the first book in more than 20 years to present a comprehensive overview of the silicon cycle and issues associated with it. The book summarizes the major outcomes of the project Land-Ocean Interactions: Silica Cycle, initiated by the Scientific Community on Problems of the Environment (SCOPE) of the International Council of Scientific Unions (ICSU). It tracks the pathway of silicon from land to sea and discusses its biotic and abiotic modifications in transit as well as its cycling in the coastal seas. Natural geological processes in combination with atmospheric and hydrological processes are discussed, as well as human perturbations of the natural controls of the silicon cycle.

Book Description
Polar Oceanography is an integrated synthesis of the biological, physical, geological, and chemical processes that occur in the polar oceans. The book represents the first modern interdisciplinary synthesis of this field.
Antarctic Sector of the Pacific
Author: G.P. GlasbyPublisher: Elsevier
ISBN: 0080870899
Category : Science
Languages : en
Pages : 415
Book Description
The Antarctic Sector of the Pacific covers the area between Australia and South America south of about 45°S. The region comprises about 6% of the Earth's surface and is amongst the most remote, hostile and least studied of the world's oceans. The scientific importance of the region is derived from its role in the reconstruction of Gondwanaland, its influence on Pacific climate and palaeoclimate and its biological productivity. No systematic surveys of the region have been undertaken since the work of the U.S.N.S. Eltanin (1962-1972). The comprehensive reassessment of whale stocks by the International Whaling Commission in 1990 and problems with ratification of the Antarctic Minerals Regime attest to the importance of Antarctic matters at present.The book will stimulate scientific activity in the region and serve as a handbook for future research. It should also appeal to oceanographers and Polar scientists.
Microbial Ecosystems of Antarctica
Author: Warwick F. VincentPublisher: Cambridge University Press
ISBN: 9780521544139
Category : Nature
Languages : en
Pages : 324
Book Description
A structured account of the full range of environments in Antarctica and of the microbial communities that live within them. The author examines the major features of the chemical and physical environment in each habitat, and the influence of these features on the population structure and dynamics of their microbiota. Each chapter considers a specific type of environment, the microbial species that dominate, their community structure and dynamics, and the microbial processes that operate and have been measured in the ecosystem. The chapters conclude with an overview of the ecosystem trophic structure and an introduction to the larger organisms that depend on the microbiota. Separate chapters examine the range of cellular strategies adopted by microorganisms within the Antarctic environment, and the increasing influence of humans on these communities.
Antarctic Ecosystems
Author: K.R. KerryPublisher: Springer Science & Business Media
ISBN: 3642840744
Category : Science
Languages : en
Pages : 428
Book Description
Antarctic Ecosystems comprises 55 papers presented at the Fifth Symposium on Antarctic Biology held under the auspices of the Scientific Committee on Antarctic Research (SCAR) in Hobart, Australia, 29 August - 3 September, 1988. Both short- and long-term changes in ecosystems and community structures caused by natural and human factors were discussed to help understand the ecological processes taking place in a changing environment. The variability of ecological factors must be known for the development of realistic monitoring strategies and sound conservation practices.
Oceanic Abstracts

Book Description
"Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea and introduced the distinctive stone tools of the Clovis culture. Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge that narrative. Their hypothesis places the technological antecedents of Clovis technology in Europe, with the culture of Solutrean people in France and Spain more than 20,000 years ago, and posits that the first Americans crossed the Atlantic by boat and arrived earlier than previously thought."--Back cover.
