Synopses & Reviews
Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 77.
The West Antarctic ice sheet is a superb recorder and cause of environmental change, with impacts that reach far beyond the Antarctic. Fortunately, fundamental advances in observing and interpreting in four dimensions are revolutionizing our ability to understand ice sheet flow related to external forcing and internal dynamics. In The West Antarctic Ice Sheet: Behavior and Environment, scientists, researchers, and students will find an invaluable resource on what changes in the ice sheet are possible, when they occur, and their implications for the environment.
