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.

摘要 ATM-9523965 King，罗德岛特雷莎大学 标题：非线性相互作用在主要冰川作用中的作用 该奖项支持一项研究，该研究将利用一组有据可查的气候系统代理时间序列来量化非线性气候系统相互作用在冰川周期中的作用。 有两个相关的目标：首先，量化更新世期间表面和深海代理数据之间的变化在空间和时间上的一致程度，与轨道强迫无关；其次，客观地区分线性受迫变化、非线性耦合变化和自由变化或内部非受迫变化。 这项研究工作的另一个好处是通过这些许多代理时间序列的组装而产生数据存档。
