About the project

该项目的主要目的是通过重建南极冰川流量和模拟这些淡水通量对pt真人电子环流和气候的影响,更好地了解南极冰盖在pt真人电子海平面和快速气候变化中的作用. 该项目的目标是末次间冰期(LIG)南极冰盖流量增加的时间间隔。, and the past millennium in marine sediments from ‘iceberg alley’, 确定末次间冰期(LIG)南极冰盖流量增加的间隔时间, and the past millennium.

末次间冰期(130-120ka):地球温度比现在高1-2℃,pt真人电子海平面比现在高6 - 9m的LIG峰值pt真人电子平均海平面高的来源仍未解决. Sights have turned to Antarctica to account for the bulk of the LIG sea level rise. 

历史(约1 ka至今):现有的南极冰川流量记录也不包括人类世, 是在非常低的分辨率,还是来自内大陆架的地点,那里的冰川流量可能受当地冰川条件的影响. 迫切需要大陆尺度的冰流量记录,以解决南极对GMSL的贡献和淡水对海洋环流的影响的历史变化. 

These records will yield an integrated (WAIS & EAIS)记录了冰川流量,并为评估南极淡水输入如何影响深水提供了新的证据, ocean circulation and other climate dynamics.
