Funds are provided for a study of Quaternary cores for the Ontong- Java Plateau ODP sites. The approach will be to eliminate the productivity effect which has a compensating effect on preservation. This will provide a "corrected" signal for preservation as a difference between shallow and deep records. Paleoproductivity signal will be obtained through the study of benthic formainifera. Ontong-Java is an ideal area for this study as productivity variations as minimal here. The study will interglacial variations in atmospheric CO2 and on the nature of acoustic reflectors in deep sea carbonates.

为研究Ontong的第四纪岩心提供了资金， 爪哇高原ODP地点。方法将是消除 生产力效应，对 保存。这将提供一个“纠正”的信号， 保存是浅记录和深记录的区别。 通过研究古生产力信号， 底栖有孔虫Ontong-Java是进行这项研究的理想地区 生产力的变化是最小的。这项研究将 间冰期大气CO2的变化以及 深海碳酸盐中的声反射体。
