The Role of Nonlinear Interactions in Major Glaciation Cycles

该奖项支持一项研究，该研究将利用一组记录良好的气候系统指标时间序列，以量化非线性气候系统相互作用在冰川循环中的作用。有两个相关的目标：第一，量化表层和深海替代数据之间的变化在更新世期间在空间和时间上的一致性程度，而不受轨道强迫的影响；第二，客观地区分线性强迫、非线性耦合和自由或内部非强迫变化。这项研究工作的另一个好处是由这些代理时间序列组合而成的数据档案。

Abstract ATM-9523965 King, Teresa University of Rhode Island Title: The Role of Nonlinear Interactions in Major Glaciation This award supports a study that will make use of a set of well- documented time series of climate system proxies in order to quantify the role of nonlinear climate system interactions in glaciation cycles. There are two related objectives: first, to quantify the extent to which variations between surface and deep ocean proxy data are spatially and temporally coherent during the Pleistocene, independent of orbital forcing; second, to objectively discriminate between linearly forced, nonlinearly coupled, and free, or internal, unforced variations. An additional benefit of this research effort will be a data archive resulting from the assembly of these many proxy time series.
