Collaborative Research: Analysis of Three Records of the Cobb Mountain Subchronozone

这是Clement （Texas a&m）和Martinson （Columbia）的合作项目。对西北大西洋ODP站点646和647沉积物的古地磁研究的初步结果表明，这些高沉积速率剖面包含了Cobb山亚时臭氧的详细记录。克莱门特对DSDP 609B孔的沉积物进行了连续采样，已经得到了这个短暂的正常极性间隔的非常详细的记录。pi将对646孔和647孔的沉积物进行更详细的采样，并对这些样品进行彻底的古地磁和岩石地磁研究，试图复制从609B孔获得的记录。他们将使用目标非线性马丁森方法定量地将每个站点的合成向量时间序列分量相互关联。这将建立一个统计基础，以评估记录中存在的相似程度。这些信息将用于检查深海沉积物作为高分辨率野外记录仪的保真度，以及记录中的差异在多大程度上可以解释为取决于地点的野外行为。

This is a collaborative project between Clement (Texas A&M) and Martinson (Columbia). Preliminary results of Paleomagnetic studies of sediments from ODP Sites 646 and 647 in the northwest Atlantic indicate that these high sedimentation rate sections contain detailed records of the Cobb Mountain Subchronozone. Continuous sampling by Clement of the sediment from DSDP Hole 609B has already yielded a very detailed record of this short, normal polarity interval. The PIs will sample the sediment from Holes 646 and 647 in more detail and conduct a thorough paleomagnetic and rock magnetic study of these samples in an attempt to replicate the record obtained from Hole 609B. They will quantitatively correlate the resultant vector time series components from each site to one another using the objectives, nonlinear method of martinson. This will establish a statistical foundation rom which to evaluate the degree to which similarities exist in the records. This information will be used to examine the fidelity of deep-sea sediments as high resolution field recorders and the extent to which the differences in the records may be explained as site dependent field behavior.
