Reihe: Geophysical Monograph Series

Published by the American Geophysical Union as part of theGeophysical Monograph Series, Volume 192.
Antarctic Subglacial Aquatic Environments is the first volumeon this important and fascinating subject. With its underlyingtheme of bridging existing knowledge to future research, it is abenchmark in the history of subglacial lake exploration and study,containing up-to-date discussions about the history and backgroundof subglacial aquatic environments and future exploration. The maintopics addressed are identification, location, physiography, andhydrology of 387 subglacial lakes; protocols for environmentalstewardship and protection of subglacial lake environments; detailsof three programs aiming to explore Vostok Subglacial Lake,Ellsworth Subglacial Lake, and Whillans Subglacial Lake over thenext 3-5 years; assessment of technological requirements forexploration programs based on best practices for environmentalstewardship and scientific success; and knowledge of subglaciallakes as habitats for microbial life and as recorders of pastclimate and ice sheet change. Its uniqueness, breadth, andinclusiveness will appeal to microbiologists and those interestedin life in extreme environments, paleoclimatologists and thoseinterested in sedimentary records of past changes, glaciologistsstriving to understand how water beneath glaciers affects theirflow, and those engaged in developing technology to undertakedirect measurement and sampling of extreme environments on Earthand in the solar system.
