Fixing Antarctica


Book Description

1956, the height of the cold war. Fourteen scientists will spend fifteen months on an isolated rock outcrop at the edge of the Antarctic plateau. Mawson station is Australia's first continental station and will become the longest continuously operating settlement inside the Antarctic Circle. The surveyor is Sydney Lorrimar Kirkby.He will go on to clock up extraordinary achievements but already he has achieved the impossible. He had polio as a child so how could he hope to pass the Commonwealth medical test? It took a bit of cunning but he got through. The age requirement for any member of an Australian Antarctic team was twenty-six years old. Syd is twenty-one. He's not a fully qualified surveyor but he will be when the ship leaves for Mawson with him on board. Over the next twenty years Syd Kirkby will explore and map more unknown regions in the world than any other person in history.Fixing Antarctica is the first full biography of this important twentieth century explorer. Told through interviews with his contemporaries, personal diaries and the diaries of other Antarctic explorers, this account establishes Kirkby in his rightful place as one of the great polar explorers.Cover Illustration: The cover of Fixing Antarctica is drawn from a portrait by Tom Macbeth, a finalist in the Archibald Prize and its associated Salon Des Refuses.




Geodetic and Geophysical Observations in Antarctica


Book Description

Due to their unique geophysical and geodynamic environment, both the Arctic and Antarctic polar regions are often utilized for geodetic and geophysical observations. This book is a collection of papers on various aspects of the scientific investigation and observation techniques of the polar regions at both temporary and permanent observatories. Most papers focus on regional models based on data acquired in polar regions. Geodetic satellite positions systems (GNSS: GPS, GLONASS, GALILEO) will also be discussed as well as other space techniques (DORIS, VLBI). Gravimetry, absolute gravimetry, and tidal gravimetry are also discussed, as well as seismology and meteorology. The book also touches on data analysis and geodynamic interpretation and discusses methods of constructing autonomous observatories.







Nitrogen Fixation by Free-Living Micro-Organisms


Book Description

This 1976 volume provides information, presented at an international symposium in Edinburgh, on the free-living nitrogen-fixing bacteria and blue-green algae. In addition to information on the distribution of the nitrogenase enzyme within these groups, their role in the soil and in aquatic systems is considered, as are the methods of measuring nitrogen fixation.




Antarctic Terrestrial Microbiology


Book Description

This book brings together many of the world’s leading experts in the fields of Antarctic terrestrial soil ecology, providing a comprehensive and completely up-to-date analysis of the status of Antarctic soil microbiology. Antarctic terrestrial soils represent one of the most extreme environments on Earth. Once thought to be largely sterile, it is now known that these diverse and often specialized extreme habitats harbor a very wide range of different microorganisms. Antarctic soil communities are relatively simple, but not unsophisticated. Recent phylogenetic and microscopic studies have demonstrated that these communities have well established trophic structuring and play a significant role in nutrient cycling in these cold and often dry desert ecosystems. They are surprisingly responsive to change and potentially sensitive to climatic perturbation. Antarctic terrestrial soils also harbor specialized ‘refuge’habitats, where microbial communities develop under (and within) translucent rocks. These cryptic habitats offer unique models for understanding the physical and biological ‘drivers’ of community development, function and evolution.




Solved


Book Description

David Miller presents a compelling case that significant progress can be made at the local level by duplicating the actions of nine leading cities around the world.




Antarctica


Book Description

A scene so wildly and awfully desolate...it cannot fail to impress me with gloomy thoughts" - so Scott perceived the stark Antarctic landscape in 1905. Antarctica traces images of the continent from early invented maps of Terra Australis Incognita up to Amundsen's arrival at 90 degrees South. Approaching Antarctica from sea and then land, the book analyses the differing perceptions of beauty and terror experienced by explorers, the stories they brought back and the power of new images refashioned at home.




Fixing the Sky


Book Description

Weaving together stories from elite science, cutting-edge technology, and popular culture, Fleming examines issues of health and navigation in the 1830s, drought in the 1890s, aircraft safety in the 1930s, and world conflict since the 1940s.




The Ecological Role of Micro-organisms in the Antarctic Environment


Book Description

This book provides up-to-date multidisciplinary information regarding microbial physiological groups in terms of their role in the Antarctic ecology. How do microorganisms shape the Antarctic environment? The book presents a thorough overview of the most important physiological microbial groups or microbial systems that shape the Antarctic environment. Each microbial model is described in terms of their physiology and metabolism, and their role in the Antarctic environmental sustainability. The individual chapters prepare readers for understanding the relevance of the microbial models from both an historical perspective, and considering the latest developments. This book will appeal to researchers and teachers interested in the Antarctic science, but also to students who want to understand the role of microbes in the ecology of extreme environments.




Microbial Ecosystems of Antarctica


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.
