Comparing the Timing and Amplitude of glacial advances in New Zealand, Chile and Antarctica-Climate Synchroneity from the Southern Hemisphere perspective

..。拟议研究的目标是解决与全球气候变化在两个半球之间的时间相移和幅度偏差有关的问题。为此，我们将利用原位宇宙成因核素测年，建立新西兰、智利和南极洲冰川事件的年表，并将结果与北半球的记录进行比较。具体地说，我们将讨论：(I)末次冰盛期(LGM)的时间演变及其衰变阶段，直到年轻的仙女木冷逆转。(2)这些活动的全球同步性问题。(3)寻找“较老的末次盛冰期”全球冰川抬升。(4)南极圈气候与南赫米斯圈其他部分的耦合。

... The goal of the proposed study is to address questions related to temporal phase shift and amplitude deviations of global climate changes between the both hemispheres. For this purpose, we will establish a chronology of glacial events in New Zealand, Chile and Antarctica by dating moraines using in situ cosmogenic nuclides and compare the results to Nothern Hemisphere records. Specifically we will address: (i) The temporal evolution of the Last Glacial Maximum (LGM) and its decay phase until the Younger Dryas cold reversal. (ii) The question of global synchroneity of these events. (iii) The search for an "older LGM" global glacial advance. (iv) The coupling of Antartic climate to the rest of the Southern Hermisphere.
