This project involves an integrated transect of boreholes on the U.S. mid-Atlantic region to address the continental margin record of the Oligocene-Recent global sea-level changes. These changes have been controlled by glacioeustatic (ice-volume) variations. Transects of passive continental margins from outcrop to the deep sea are needed to evaluate the timing and amplitude of sea-level variations. The transect requires drilling both onshore and offshore (ODP Leg 150). The Principal Investigators will drill three continuously cored and logged boreholes in the New Jersey coastal plain near Island Beach, Atlantic City, and Cape May, NJ. The project will be a collaborative effort among Rutgers, LDGO/Columbia, and the Eastern Regional Branch of the USGS. The multidisciplinary use of magnetostratigraphy, biostratigraphy, Sr-isotope stratigraphy and oxygen isotope glacioeustatic curves combined with seismic stratigraphy to tie together onshore and offshore wells will provide a comprehensive data set. The geologic record of sea level changes gives factual constraints for developing models of global paleoclimatological change.

该项目涉及美国大西洋中部地区的综合钻孔横断面，以解决渐新世至近期全球海平面变化的大陆边缘记录。 这些变化受到冰川平衡（冰量）变化的控制。 需要从露头到深海的被动大陆边缘横断面来评估海平面变化的时间和幅度。 该样线需要陆上和海上钻探（ODP Leg 150）。 主要研究人员将在新泽西州大西洋城岛屿海滩附近的沿海平原和新泽西州五月岬附近钻三个连续取芯和测井的钻孔。 该项目将由罗格斯大学、LDGO/哥伦比亚大学和美国地质勘探局东部地区分部共同合作完成。 磁性地层学、生物地层学、锶同位素地层学和氧同位素冰川平衡曲线的多学科应用与地震地层学相结合，将陆上和海上井联系在一起，将提供全面的数据集。 海平面变化的地质记录为开发全球古气候变化模型提供了事实约束。
