Biogenic Chemical Records in Deep-Sea Sediments and their Application to Paleoceanographic Study

这项研究将继续一个项目，研究气候引起的海洋生物沉积变化。岩心样品中发现的生物成因物质的类型随着古气候的不同而不同，因此似乎受到温度的控制。这一研究项目将开发更快速的分析生物成因物质的方法，将早期的研究扩展到较老的沉积物和其他已经独立估计地温的岩心。这项研究的结果将有助于理解气候变化期间海洋初级生产力变化的原因。

This research will continue a project to study climatically induced changes in biogenic sedimentation in the oceans. The type of biogenic material found in core samples varies with the paleoclimate and, therefore, appears to be temperature controlled. This research project will develop more rapid methods for doing the analysis of the biogenic material, an extend the earlier studies to both older sediment and other cores where independent estimates of paliotemperature have been made. The results of this research will lead to the understanding of causes for changes in primary productivity in the oceans during climatic changes.
