Download or read book Antarctic Sector of the Pacific written by G.P. Glasby and published by Elsevier. This book was released on 1989-02-07 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Antarctic Environments and Resources written by J.D. Hansom and published by Routledge. This book was released on 2014-06-03 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antarctica is no longer a 'pole apart'. From a scientific perspective, the Antarctic ice sheet, ocean and climate systems are intimately linked with the global climate and are now seen to be of international significance for understanding climate change. From an economic perspective, the Antarctic is perceived to have great potential as a source of marine resources although the extent of speculated mineral and hydrocarbon resources is unknown. From a conservation perspective, the continent of Antarctica represents the ideal image of unspoiled wilderness. Antarctic Environments and Resources is an accessible and timely new geography of the Antarctic which examines the differing and sometimes conflicting interests in the great southern continent, the Southern Ocean and the subantarctic islands against a background of the physical and natural systems of the region and their interactions. It charts the development of human involvement in the area, focusing on the exploitation of resources from early sealing to modern fisheries, tourism and science, and it assesses the consequent impacts on the natural environment. The text also reviews the emerging framework for future environmental management developed under the Antarctic Treaty System. This is an ideal text for undergraduates studying glacial geomorphology, environmental management, polar regions and the Antarctic.

Download or read book Polar Environments and Global Change written by Roger G. Barry and published by Cambridge University Press. This book was released on 2018-08-09 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The polar regions are the 'canary in the coal mine' of climate change: they are likely to be hit the hardest and fastest. This comprehensive textbook provides an accessible introduction to the scientific study of polar environments against a backdrop of climate change and the wider global environment. The book assembles diverse information on polar environmental characteristics in terrestrial and oceanic domains, and describes the ongoing changes in climate, the oceans, and components of the cryosphere. Recent significant changes in the polar region caused by global warming are explored: shrinking Arctic sea ice, thawing permafrost, accelerating loss of mass from glaciers and ice sheets, and rising ocean temperatures. These rapidly changing conditions are discussed in the context of the paleoclimatic history of the polar regions from the Eocene to the Anthropocene. Future projections for these regions during the twenty-first century are discussed. The text is illustrated with many color figures and tables, and includes further reading lists, review questions for each chapter, and a glossary.
Download or read book Upper Ocean Physical and Ecological Dynamics in the Ross Sea Antarctica written by Matthew Charles Long and published by Stanford University. This book was released on 2010 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines several aspects of the unique physical-biological system that controls biogeochemical cycling in the Ross Sea, the largest continental shelf sea along the Antarctic margin and the most biologically productive region in the Southern Ocean. The core component of the research involves interpretation of data from two oceanographic cruises to the region, one during Summer of 2005--2006 and another in Spring of 2006--2007. Four key research questions are addressed. (1) What physical mechanisms force spatial and temporal variability in mixing depths? (2) How does the dynamic physical environment characteristic of Antarctic continental shelf seas structure distributions of biomass and chemical tracers of production? (3) What key physical and physiological mechanisms control the 13C/12C ratio of organic and inorganic carbon in waters on the Ross Sea continental shelf? and (4) How do physiological variables interact with environmental variability to control phytoplankton taxonomic zonation? Chapter 1 presents an introduction to ocean carbon biogeochemistry and the oceanography of the Southern Ocean and the Ross Sea. Chapter 2 examines the mechanisms effecting early season stratification in the Ross Sea. Lateral advection in the region of upper ocean fronts is shown to be an important mechanism setting early season stratification. Chapter 3 examines several tracer-based methods for estimating upper ocean net community production in the Ross Sea, with explicit recognition of the complexities associated with control volume assumptions and high rates of temporal change. Chapter 4 considers the environmental controls on the distribution of 13C/12C ratios in the Ross Sea. It is shown quantitatively that the two dominant phytoplankton taxa in the Ross Sea have different intrinsic fractionation factors, likely as a result of differing carbon-acquisition physiologies. Air-sea exchange is shown to occur with very noisy fractionation. Finally, Chapter 5 examines the interaction of algal physiology with environmental variability, addressing the key physiological-environmental controls on the taxonomic distribution of phytoplankton in the Ross Sea. While it is difficult to draw concrete conclusions, the most compelling line of evidence suggests that differing photoprotective capacities is the most important physiological characteristic structuring taxonomic distributions. An appendix presents a design for an infrared absorbance-based instrument for the determination of total dissolved inorganic carbon in seawater.

Download or read book Antarctic Ocean and Resources Variability written by Dietrich Sahrhage and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the intensification of research activities in the Southern Ocean in recent years, both at national levels and through international cooperation in such projects as BIOMASS with its FIBEX and SIBEX phases, the need was felt increasingly for closer collaboration between biologists, meteorologists, and oceanographers in the study of the interaction between the atmospheric forces, the water masses, and the living resources. Better knowledge in this regard is not only of scientific interest but also of practical importance, especially for the management of the resources and the protection of the Antarctic marine ecosystem. As a follow-up on a recommendation by the IOC Program Group for the Southern Oceans made in March 1983, the Intergovernmental Oceanographic Commission organized a meeting of experts on oceanography related to the dynamics of the Antarctic ecosystems. During this meeting, held in Kiel, Federal Republic of Ger many, in May 1984, biologists and oceanographers involved in BIOMASS activities met with the oceanographers of SCOR Working Group 74 to discuss ways and means for additional physical and chemical observations in the oceanographic research within BIOMASS. It was the time when large fluctuations in the distribution of krill with subsequent detrimental effects on predator species dependent on krill had just been observed, and the question arose whether this was possibly the result of changes in the Antarctic water circulation.
