Book excerpt: Data from the Electrically Scanning Microwave Radiometer (ESMR) on the Nimbus 5 satellite are used to determine the extent and distribution of Antarctic sea ice. The characteristics of the southern ocean, the mathematical formulas used to obtain quantitative sea ice concentrations, the general characteristics of the seasonal sea ice growth/decay cycle and regional differences, and the observed seasonal growth/decay cycle for individual years and interannual variations of the ice cover are discussed. The sea ice data from the ESMR are presented in the form of color-coded maps of the Antarctic and the southern oceans. The maps show brightness temperatures and concentrations of pack ice averaged for each month, 4-year monthly averages, and month-to-month changes. Graphs summarizing the results, such as areas of sea ice as a function of time in the various sectors of the southern ocean are included. The images demonstrate that satellite microwave data provide unique information on large-scale sea ice conditions for determining climatic conditions in polar regions and possible global climatic changes.

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.

Available in PDF, EPUB and Kindle. Book excerpt: BIOMASS (Biological Investigations of Marine Antarctic Systems and Stocks) was a unique, large-scale, long-term, international research programme established in 1977 to investigate the ecology of the Southern Ocean. Its main aim was to gain a greater understanding of the biological systems and stocks in the marine Antarctic environment, thereby providing a sound basis for the future management of the living resources within this immense ocean. The programme was drawn to a close in 1991 and its completion marked by a colloquium which brought together key researchers to summarise and review the results obtained. This volume, arising from that colloquium, provides a succinct, state-of-the-art account of the ecology of the Southern Ocean and serves as a comprehensive record of this unique and successful international project.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Monthly Antarctic Sea Ice Extent Variability Since 1957 from Reconstructions and Observations written by Beatrice K. Waters and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As climate change continues unabated, understanding Earth’s complex climate system remains critical. The Antarctic climate system is a crucial part of this system, and the sea ice surrounding the continent is an incredibly important element. With the largest change in albedo on Earth, Antarctic sea ice is responsible for reflecting solar radiation from the region. As seen in the Arctic as a result of climate change, without sea ice this solar radiation is absorbed by the low albedo ocean causing warming and further melt of sea ice in a positive feedback loop. Antarctic sea has not responded in the same way as the Arctic. Observations of Antarctic sea ice date back to October 1978 and have shown an overall increase in sea ice. A sudden decline in sea ice extent in 2016 was an unexpected turn of events, and a new record low extent in February 2023 has further complicated this. Due to the short records of Antarctic sea ice extent and the complex nature of the regional climate system, it is difficult to isolate the impacts of climate change in the region. To expand these short records, reconstructions have been utilized. Monthly reconstructions, based on observational temperature and pressure data, were created in order to extend this record to 1957. These reconstructions were analyzed in this study in order to determine their skill and understand how Antarctic sea ice extent has changed through the 1957-2020 period. This was done for the total sea ice extent around the Antarctic continent as well as the Bellingshausen-Amundsen, East Antarctic, King Hakon, Ross, and Weddell regions. The reconstructions were analyzed using correlation, regression, and comparison of means statistical methods in order to evaluate relationships between Antarctic climate data and sea ice extent, relationships between modes of climate variability and sea ice extent, changes in the seasonal cycle of sea ice extent, and trends in sea ice extent. It was of interest to determine if there were changes between the early 1957-1978 period and the 1979-2020 observational period, as this is a likely indicator of reconstruction performance. It was found that the monthly reconstructions generally have a high level of skill. Relationships between sea ice extent and Antarctic climate data and between sea ice extent and climate modes of variability were typically maintained. Specifically, the dipole relationship (increasing versus decreasing sea ice extent) between the Bellingshausen-Amundsen and Ross regions was demonstrated in the relationships analyzed in this study. Analysis of the seasonal cycle revealed changes through time, including statistically significant changes in annual sea ice growth for the total extent, Ross, King Hakon, and Weddell regions. Trend analysis suggests that the monthly reconstructions may capture the mid-century regime shift in sea ice extent found in Fogt et al. (2022), although this is not true for all sectors, specifically Ross. Correlations between these seasonal reconstructions and the monthly reconstructions analyzed in this study were highly variable and more analysis is needed to determine the cause. This study provides a crucial initial analysis of previously unanalyzed monthly SIE reconstructions. Extending the SIE record is a critically important part of understanding the future of Antarctic climate.
