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
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
A wondrous story of scientific endeavor—probing the great ice sheets of Antarctica From the moment explorers set foot on the ice of Antarctica in the early nineteenth century, they desired to learn what lay beneath. David J. Drewry provides an insider’s account of the ambitious and often hazardous radar mapping expeditions that he and fellow glaciologists undertook during the height of the Cold War, when concerns about global climate change were first emerging and scientists were finally able to peer into the Antarctic ice and take its measure. In this panoramic book, Drewry charts the history and breakthrough science of radio-echo sounding, a revolutionary technique that has enabled researchers to measure the thickness and properties of ice continuously from the air—transforming our understanding of the world’s great ice sheets. To those involved in this epic fieldwork, it was evident that our planet is rapidly changing, and its future depends on the stability and behavior of these colossal ice masses. Drewry describes how bad weather, downed aircraft, and human frailty disrupt the most meticulously laid plans, and how success, built on remarkable international cooperation, can spawn institutional rivalries. The Land Beneath the Ice captures the excitement and innovative spirit of a pioneering era in Antarctic geophysical exploration, recounting its perils and scientific challenges, and showing how its discoveries are helping us to tackle environmental challenges of global significance.

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.

Book Description
In 2016, scientist Rosaly Lopes and artist Michael Carroll teamed up as fellows of the National Science Foundation to travel to Mount Erebus, the world’s southernmost active volcano in Antarctica. The logistics of getting there and complex operations of Antarctica's McMurdo Station echo the kinds of strategies that future explorers will undertake as they set up settlements on Mars and beyond. This exciting popular-level book explores the arduous environment of Antarctica and how it is similar to other icy worlds in the Solar System. The bulk of this story delves into Antarctica’s infrastructure, exploration, and remote camps, culminating on the summit of Erebus. There, the authors explored the caves and ice towers on the volcano’s flanks, taking photographs and generating original art depicting scenes in Antarctica and terrestrial analogs on other planets and moons. Readers will see an intimate side of Mount Erebus and Antarctica while surveying the region’s history, exploration, geology, and volcanology, which includes research funded by the National Science Foundation’s United States Antarctic Programs. Richly illustrated with photographs and stunning paintings showcasing the beauty of the harsh continent, the book captures the spirit and splendor of the authors’ journey to Erebus.
