Book Description
Antarctica is renowned for its extreme cold; yet surprisingly, radar measurements have revealed a vast network of lakes, rivers, and streams several kilometers beneath the Antarctic ice sheet. Sealed from Earth's atmosphere for millions of years, they may provide vital information about microbial evolution, the past climate of the Antarctic, and the formation of ice sheets, among other things. The next stage of exploration requires direct sampling of these aquatic systems. However, if sampling is not done cautiously, the environmental integrity and scientific value of these environments could be compromised. At the request of the National Science Foundation, this National Research Council assesses what is needed to responsibly explore subglacial lakes. Exploration of Antarctic Subglacial Aquatic Environments concludes that it is time for research on subglacial lakes to begin, and this research should be guided by internationally agreed upon protocols. The book suggests an initial protocol, which includes full characterization of the lakes by remote sensing, and minimum standards for biological and other types of contamination.

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 192. Antarctic Subglacial Aquatic Environments is the first volume on this important and fascinating subject. With its underlying theme of bridging existing knowledge to future research, it is a benchmark in the history of subglacial lake exploration and study, containing up-to-date discussions about the history and background of subglacial aquatic environments and future exploration. The main topics addressed are identification, location, physiography, and hydrology of 387 subglacial lakes; protocols for environmental stewardship and protection of subglacial lake environments; details of three programs aiming to explore Vostok Subglacial Lake, Ellsworth Subglacial Lake, and Whillans Subglacial Lake over the next 3–5 years; assessment of technological requirements for exploration programs based on best practices for environmental stewardship and scientific success; and knowledge of subglacial lakes as habitats for microbial life and as recorders of past climate and ice sheet change. Its uniqueness, breadth, and inclusiveness will appeal to microbiologists and those interested in life in extreme environments, paleoclimatologists and those interested in sedimentary records of past changes, glaciologists striving to understand how water beneath glaciers affects their flow, and those engaged in developing technology to undertake direct measurement and sampling of extreme environments on Earth and in the solar system.

Book Description
Our appreciation of glaciological processes in Antarctica suffers from a lack of observations in regions where numerical models indicate the ice sheet to be susceptible to ocean and/or atmospheric warming. The solution lies in the use and development of glacier geophysics. In this volume we present a series of papers that demonstrate how geophysics can be deployed in Antarctica to comprehend: (1) boundary conditions that influence ice flow such as subglacial topography, the distribution of basal water and ice-sheet rheology; (2) phenomena that might affect ice-flow processes, such as complex internal ice-sheet structures and the proposition of large stores of hitherto unappreciated groundwater; and (3) how glacigenic sediments and formerly glaciated terrain on, and surrounding, the continent can inform us about past ice-sheet dynamics. The volume also takes a historical view on developments leading to current knowledge, examines active ice-sheet processes, and points the way forward on how geophysics can advance quantitative understanding of Antarctic ice-sheet behaviour.

Book Description
This book provides an overview of the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. It describes each ecosystem type, the remarkable aquatic life that thrives in these extreme habitats, and the similarities and differences between Arctic and Antarctic waters.

Book Description
The Antarctic Treaty (1959) was adopted for the purpose of bringing peace and stability to the region and to facilitate cooperation in scientific research conducted on and around the continent. It has now been over fifty years since the Antarctic Treaty's entry into force, nevertheless, security continues to both drive and shape the legal and policy regime which applies to Antarctica. This book explores a wide range of Antarctic and Southern Ocean issues through the lens of security. The contributions to this volume engage with a security discourse which has expanded beyond the traditional military domain to include notions of economic security, environmental security, food security, bio-security, heath security and human security. The chapters consider topics such as the implications for Antarctica and the Southern Ocean of the growing strategic competition between the rising powers of Asia, the possible effects of climate change on the authority, legitimacy and effectiveness of the Antarctic Treaty System, and the shift from 'strategic' security to 'human' security and its potential consequences for the Antarctic treaty regime.

Book Description
Global change assessments inform decision makers about the scientific underpinnings of a range of environmental issues, such as climate change, stratospheric ozone depletion, and loss of biodiversity. Dozens of assessments have been conducted to date by various U.S. and international groups, many of them influencing public policies, technology development, and research directions. This report analyzes strengths and weaknesses of eight past assessments to inform future efforts. Common elements of effective assessments include strong leadership, extensive engagement with interested and affected parties, a transparent science-policy interface, and well defined communication strategies. The report identifies 11 essential elements of effective assessments and recommends that future assessments include decision support tools that make use of information at the regional and local level where decisions are made.

Book Description
. . . an impressive volume and the editors have put together a high quality collection. Research Handbook on International Environmental Law ought to be an invaluable reference source for both teachers and students of international environmental law in the years to come. Web Journal of Current Legal Issues This wide-ranging and comprehensive Handbook examines recent developments in international environmental law (IEL) and the crossover effects of this expansion on other areas of international law, such as trade law and the law of the sea. The expert contributors offer analyses of foundational issues in IEL, such as responsibility for environmental damage, sustainable development and the precautionary principle, alongside studies in topical subject areas including marine protection and the law of international watercourses. This Research Handbook offers an in-depth analysis of IEL, both as a field of law in its own right, and as part of the wider system of international law. It gives a comprehensive view of IEL in all its forms and complexity. With thorough examination of specific environmental regimes and compliance mechanisms, this Handbook will be an indispensable resource for legal scholars, students and practitioners alike.
