        The Antarctic Ice Sheet is losing mass at an accelerating pace, and ice loss will likely continue over the coming decades and centuries. Some regions of the ice sheet may reach a tipping point, potentially leading to rates of sea level rise at least an order of magnitude larger than those observed now, owing to strong positive feedbacks in the ice-climate by: 1.   There is evidence that a self-sustaining ice discharge from the West Antarctic Ice Sheet (WAIS) has started, potentially leading to its disintegration. The associated sea level rise of more than 3m would pose a serious challenge to highly populated areas including metropolises such as Calcutta, Shanghai, New York City, and Tokyo. Here, we show that the WAIS may be Cited by: 1.

Dynamics of the West Antarctic Ice Sheet: Proceedings of a Workshop held in Utrecht, May 6–8, (Glaciology and Quaternary Geology)Format: Hardcover. ` All in all this is splendid book. It brings together different viewpoints and presents a `state of the art' account of the dynamics of the West Antarctic Ice Sheet.

It opens up new horizons both within glaciology as a whole and in Antarctica. A number of processes can be listed that could all lead to changes of the order of tens of centimeters (e. thermal expansion, change in mass balance of glaciers and ice sheets).

But the picture of the carbon dioxide problem has frequently be made more dramatic by suggesting that the West Antarctic Ice Sheet is unstable, implying a certain. The new data indicate that the West Antarctic Ice Sheet (WAIS) extended to the shelf edge of Pine Island Bay during the last glaciation, and was drained by a grounded, fast-flowing palaeo-ice stream through this outer-shelf by:   Extent and dynamics of the West Antarctic Ice Sheet on the outer continental shelf of Pine Island Bay during the last glaciation Evans, Jeffrey Dowdeswell, Julian by:   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.

The behavior of Ice Streams A to E of the Siple Coast, West Antarctica has attracted much attention with evidence of recent stagnation and numerous relict ice‐flow by: If the West Antarctic Ice Sheet (WAIS) melted, sea levels would rise by about 5 m; such changes are thought to have occurred in the past but could not be Cited by:   Fig.

The WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves.

As a result, the seven scientists suggested that the positions of ice-stream margins and their onsets were controlled by features of the underlying sedimentary basins; and they concluded that “geological structures beneath the West Antarctic Ice Sheet have the potential to dictate the evolution of the dynamic ice system, modulating the influence of changes in the global.
