Download or read book The International Politics of Antarctica (Routledge Revivals) written by Peter J. Beck and published by Routledge. This book was released on 2014-06-17 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1986, this book considers the nature of international interest in Antarctica and the positions of those involved. It looks at the significance of the historical dimension, the development of the treaty system, the management of marine and mineral resources, the role of the United Nations and the impact of such non-governmental organisations as Greenpeace International. The Antarctic implications of the Falklands War of 1982 are also discussed, as well as the underlying relationship between America and the Soviet Union during the 1980s. With a truly international scope, this reissue will be of particular relevance to students with an interest in the political, legal, economic and environmental concerns surrounding the Antarctic region, both in the present and historically.

Download or read book Antarctica and the Southern Ocean written by Nicholas Golledge and published by Frontiers Media SA. This book was released on 2024-06-26 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antarctica is our southernmost continent. It is nearly double the size of Australia. Antarctica is covered almost entirely by land ice called the Antarctic Ice Sheet and is surrounded by the Southern Ocean. The Southern Ocean influences climate by taking up heat and carbon dioxide from the atmosphere and storing it in deep waters. The cloud processes and aerosols over the Southern Ocean are complex and are important challenges for climate models. To understand the climate of the past, polar scientists drill ice cores through the Antarctic Ice Sheet. The ice core is a powerful tool that we can use to determine how the Earth's climate has changed and the information provided by historical ice cores has become extremely valuable for predicting the future scenarios of our planet. This ice is the largest reservoir of fresh water on Earth. The Antarctic Ice Sheet flows down into the Southern Ocean where parts of it start to float. These large floating platforms of ice are called ice shelves. Knowledge of the sensitivity and interaction of ice shelves to changes in atmosphere and ocean is important to understand the contribution of Antarctica to global sea level rise and the Southern Ocean, and global marine ecosystems. If melted, the Antarctic Ice Sheet would be a major contributor to global sea level rise. In winter, the surface of the ocean around Antarctica freezes and sea ice forms. At the height of winter, the area of sea ice that forms is as large as Antarctica itself but it melts back to the continent every summer. The amount of sea ice that forms in winter and melts back each summer is different. We examine this annual fluctuation of sea ice area around Antarctica for indications of climate change. Sea ice provides important habitats for primary producers, such as sea ice algae, and Antarctic krill, a keystone species of the Southern Ocean ecosystem. Sea ice is also an important habitat for penguins and seals. This collection aims to inform young readers about fundamental knowledge and digested cutting-edge science that will help increase their understanding of Antarctica and its central role as a global climate driver. In addition to the Editors hosting, we would acknowledge the coordination and organization efforts of Pat Wongpan .

Download or read book Future Science Opportunities in Antarctica and the Southern Ocean written by National Research Council and published by National Academies Press. This book was released on 2011-11-28 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antarctica and the surrounding Southern Ocean remains one of the world's last frontiers. Covering nearly 14 million km² (an area approximately 1.4 times the size of the United States), Antarctica is the coldest, driest, highest, and windiest continent on Earth. While it is challenging to live and work in this extreme environment, this region offers many opportunities for scientific research. Ever since the first humans set foot on Antarctica a little more than a century ago, the discoveries made there have advanced our scientific knowledge of the region, the world, and the Universe-but there is still much more to learn. However, conducting scientific research in the harsh environmental conditions of Antarctica is profoundly challenging. Substantial resources are needed to establish and maintain the infrastructure needed to provide heat, light, transportation, and drinking water, while at the same time minimizing pollution of the environment and ensuring the safety of researchers. Future Science Opportunities in Antarctica and the Southern Ocean suggests actions for the United States to achieve success for the next generation of Antarctic and Southern Ocean science. The report highlights important areas of research by encapsulating each into a single, overarching question. The questions fall into two broad themes: (1) those related to global change, and (2) those related to fundamental discoveries. In addition, the report identified key science questions that will drive research in Antarctica and the Southern Ocean in coming decades, and highlighted opportunities to be leveraged to sustain and improve the U.S. research efforts in the region.
