Definition
- The project consists of collecting field measurements needed to better understand and then to model the dynamic behavior of coastal outlet glaciers through which does most of the drainage of the ice to the sea This study follows the observation a recent acceleration of Greenland glaciers coastal responsible for a notable decrease in the overall mass balance of the ice and therefore an increased contribution to sea level (Rignot and Kanagaratnam, 2006). If a similar trend for states West Antarctica with the disappearance of 'ice shelves', thinning and acceleration of certain concomitant large outlet glaciers (eg Pine Island Glacier, Rignot, 1998), role of East Antarctica, although potentially more threatening in terms of sea level is still poorly defined. The work proposed here intends to measure and model the present and future development of the area that is the workshop of the Astrolabe glacier (logistic facilities) as well as large outlet glaciers more distant (Ninnis, Mertz, Dibble, Terre Adélie sector - George V Land) which by their size, drain a significant portion of the East Antarctic ice cap (annual flows of ice in the order of several tens of km 3 per year).
