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, and extend the earlier studies to both older sediment and other cores where independent estimates of paleotemperature 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.

这项研究将继续进行一个研究海洋生物沉积中气候引起的变化的项目。在岩心样品中发现的生物物质类型随古气候而变化，因此似乎是受温度控制的。这个研究项目将开发出更快速的方法来分析生物物质，并将早期的研究扩展到更古老的沉积物和其他已经独立估计古温度的岩心。这项研究的结果将有助于了解气候变化期间海洋初级生产力变化的原因。
