Funds are being provided for the PIs to undertake a high-resolution study of the Oligocene shallow-water drill sites to determine linkages between oxygen-isotopic record and the sea-level variations. Both faunal and stable-isotopic studies of the ODP cores and onshore sites on the New Jersey margin are planned. The PIs will use the litho-and biofacies data to determine paleowater depth at Milankovitch scale resolution and will attempt new estimates of the magnitude of sea-level changes. Onshore Oligocene daa will be used to reconstruct a high-resolution oxygen-isotopic record. Detailed chronostratigraphy will provide a sense of leads and lags between changes in sea level and the sediment response.

目前正在为项目研究员提供资金，以便对渐新世浅水钻井地点进行高分辨率研究，以确定氧同位素记录与海平面变化之间的联系。 计划对新泽西边缘的ODP岩心和陆上地点进行动物群和稳定同位素研究。 PI将使用岩石和生物相数据来确定米兰科维奇尺度分辨率的古水深度，并将尝试对海平面变化幅度进行新的估计。 陆上渐新统数据库将用于重建高分辨率氧同位素记录。 详细的年代地层学将提供海平面变化和沉积物响应之间的超前和滞后的感觉。
