Book Description
The Antarctic continent carries the greatest diversity of lake environments on the planet: freshwater and saline lakes, tidal freshwater epishelf lakes, lakes on ice shelves and glacier surfaces, and over three hundred subglacial lakes; extraordinary ecosystems that have been separated from the atmosphere for up to millions of years. This book provides a unique and cutting edge synthesis of Antarctic limnology, drawing together current knowledge on geomorphology, morphometry, chemistry, community structure and function. It emphasises throughout the value of these near-pristine ecosystems as barometers of climate change, showing how responsive and vulnerable they are to the indirect impacts of anthropogenic activity. Antarctic Lakes begins with an introduction to their physical, chemical, and biological characteristics, providing a basis for understanding the subsequent detailed chapters on different lake types, and ends with a chapter considering the application of new technologies to polar limnology as well as identifying future research directions. This accessible text is suitable for both senior undergraduate and graduate students taking courses in Antarctic and polar limnology, and will also be of broad interest to researchers working in the areas of polar science, microbial ecology (and extremophiles), climatology, glaciology, and astrobiology.

Book Description
Concerns about the effects of global climate change have focused attention on the vulnerability of circumpolar regions. This book offers a synthesis of the spectrum of techniques available for generating long-term environmental records from circumpolar lakes.

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
This book provides an intriguing look at how life can adapt to many different extreme environments. It addresses the limits for life development and examines different strategies used by organisms to adapt to different extreme environments.

Book Description
Diatoms are an important element of many polar marine microbial communities and particularly abundant in Antarctic lakes. However, few comprehensive studies, such as the study presented in this volume are available on Antarctic communities. The diatom floras encountered in surface sediment samples from 33 lakes of the Vestfold Hills, Antarctica are presented. 67 distinct diatom species were identified in these sediments. They include cosmopolitan, Southern Ocean, endemic Antarctic and new diatoms. Each species encountered is described and illustrated; autecological information on the species is included where possible. Epilimnion water chemistry of the lakes sampled was determined to investigate their influence on diatom distribution. The studied lakes span a very large range of salinities from 0.5 to 165 permil. The authors show that salinity seems to have a strong influence on the observed diatom taxa.

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
The first book on the subject, this monograph examines the phenomenon of a huge sealed, freshwater lake, isolated from the rest of the world by kilometers' thick ice. The existence of melting ice at the bottom of the huge Vostok Lake has served as a model and inspired the team planning the Galileo space craft to gather data on the ice sheet of the Jupiterian moon Europa. The book provides interpretation of, and calculations for, stimulating factors for possible melting and a huge lake's existence at the bottom of the Martian ice sheets.
