Late Quaternary Warm Events in the Southern Ocean, Their Impact upon the Stability of the West Antarctic Ice Sheet

该奖项支持对南部沉积物芯的研究 海洋提取和解释古海洋学和古气候 信息. 该项目将审查 南大洋条件的冰川/间冰期变化可能 对南极洲西部冰盖的稳定性产生了影响。 古海洋学条件，特别是海面温度 以及过去的循环模式，将被重建， 研究花卉（硅藻）组成，蛋白石百分比，百分比 碳酸盐和深海岩心中的锗硅比。 这些信息作为古气候模型的输入是重要的， 海洋和南极西部冰之间相互作用的模式 床单。

This award supports a study of sediment cores from the Southern Ocean to extract and interpret paleoceanographic and paleoclimatic information. The project will examine the impact that glacial/interglacial changes in Southern Ocean conditions might have had on the stability of the West Antarctic Ice Sheet. Paleoceanographic conditions, specifically sea-surface temperatures and circulation patterns in the past, will be reconstructed by studying floral (diatom) composition, percent opal, percent carbonate, and the Germanium-Silicon ratio in deep ocean cores. This information is important as input to paleoclimatic models and models of interaction between oceans and the West Antarctic Ice Sheet.
