This award is for support for a two year program of ice sheet modeling to contribute to the site selection for deep drilling at the inland site for the West Antarctic ice cores (WAISCORES) program. Ice flow calculations will be performed to provide time- scale and layer thickness estimates, and to identify source regions of deep ice. The research will focus on finding sites where the climate record should be best preserved throughout its long ice dynamics history. Using existing radar data and ice dynamical models sites will be identified that optimize age resolution and avoid potentially disturbed basal ice. The work will be closely coordinated with the ice coring community and other investigators who are trying to identify areas with good depositional environments and firn preservation. The project is a collaboration between the University of Texas Institute for Geophysics and the University of Washington Geophysics program.

该奖项是为了支持一个为期两年的冰盖建模项目，为南极西部冰芯（WAISCORES）项目内陆深度钻探的选址做出贡献。冰流计算将进行，以提供时间尺度和层厚度估计，并确定深冰的来源区域。研究将集中于寻找在其漫长的冰动力学历史中气候记录应该得到最好保存的地点。利用现有的雷达数据和冰动力模型，将确定优化年龄分辨率的地点，并避免潜在的扰动基冰。这项工作将与冰芯社区和其他研究人员密切协调，他们正在努力确定具有良好沉积环境和坚硬保存的地区。该项目是德克萨斯大学地球物理研究所和华盛顿大学地球物理项目的合作项目。
