项目摘要

Intellectual Merit: Neogene sediment records recovered by ANDRILL suggest multiple events of open water conditions and elevated sea surface temperatures at times when terrestrial data from the McMurdo Dry Valleys indicate hyper arid, cold, desert conditions. Interpretation of the ANDRILL data suggests the West Antarctic Ice Sheet is highly sensitive to changes in Pliocene sea surface temperatures and this conclusion has been supported by recent Global Circulation Model results for the early to mid Pliocene. The PIs propose to model paleo-ice configurations and warm orbits associated with a WAIS collapse to assess potential climate change in East Antarctica. During such episodes of polar warmth they propose to answer: What is the limit of ablation along the East Antarctic Ice Sheet?; Are relict landforms in the Dry Valleys susceptible to modification from increase in maximum summertime temperatures?; and Is there sufficient increase in minimum wintertime temperatures to sustain a tundra environment in the Dry Valleys? Integration of depositional records and model outputs have the potential to test the performance of numerical models currently under development as part of ANDRILL; reconcile inconsistencies between marine and terrestrial paleoclimate records in high Southern Latitudes; and improve understanding of Antarctic climate and ice volume sensitivity to forcing for both the East Antarctic and West Antarctic Ice Sheets. Broader impacts: Results from this study have the potential to be used widely by the research community. Outreach to local elementary schools from other funded efforts will continue and be extended to homeschooled students. A Post Doc will be supported as part of this award.
智力优势:安德里尔恢复的新近纪沉积物记录表明,当麦克默多干谷的陆地数据表明超干旱、寒冷、沙漠条件时,有多个开放水域条件和海面温度升高的事件。对ANDRILL数据的解释表明,南极西部冰盖对上新世海面温度的变化高度敏感,这一结论得到了最近全球环流模式上新世早期至中期结果的支持。PI建议模拟与WAIS崩溃相关的古冰配置和温暖轨道,以评估东南极洲的潜在气候变化。在这样的极地变暖期间,他们打算回答:沿东南极冰盖沿着消融的极限是什么?干旱河谷的残余地形是否易受夏季最高温度升高的影响?是否有足够的最低冬季温度的增加,以维持在干旱山谷苔原环境?沉积记录和模型输出的整合有可能测试目前正在开发的数值模型的性能,作为ANDRILL的一部分;调和南半球高纬度地区海洋和陆地古气候记录之间的不一致;并提高对南极气候和冰量敏感性的理解,以迫使东南极和西南极冰盖。更广泛的影响:这项研究的结果有可能被研究界广泛使用。将继续从其他资助的努力中向当地小学推广,并扩大到在家上学的学生。一个邮政文件将支持作为此奖项的一部分。
