Ice Sheets and Late Quaternary Environmental Change provides a detailed account of the temporal and spatial distribution of ice sheets during the last ice age, and how these ice masses interacted with the environment. This is the first book in 20 years to detail the sizes of ice sheets during the last glaciation and the first to discuss their role in past climate change. Arranged in two parts, the first part provides the tools required for evaluating past ice sheets while the second part uses these tools to establish the size, extent and dynamics of late Quaternary ice sheets. Assuming no prior knowledge of Quaternary Science, the discussion progresses from the basic principles of how and why ices ages occur, to the interpretation of proxy records of past climate and ocean change. Instructive accounts of how the geological record can be used as evidence of former ice sheet behaviour and a discussion on the role of numerical models in understanding interaction between ice sheets, oceans and the atmosphere are included in this book. Details of former ice sheets are presented by geographical region along with a number of critical new theories on their size and behaviour. This book would appeal to 2nd/3rd year students of Quaternary Science, most University Geography, Earth Science or Geology departments, as well as researchers and academics in Quaternary Science.

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.
