Funds are provided for the PIs to study the Upper Cretaceous to Lower Paleogene and Quaternary unconformities and stratal patterns on the New York and New Jersey margins. Two separate but fundamental questions to stratigraphy of the margins are to be addresed: how sequence boundaries and stratigraphic discontinuities formed during times of reduced sealevel fluctuations, and why the Quaternary section does not have unconformities associated with each sealevel cycle. The PIs plan to acquire side-scan sonar images, Chirp images (for subseafloor shallow features), MCS images and vinracores from this area. They will also use ODP site 1073 for chronology. These data will provide a high-resolution physical stratigraphy and precise chronology leading to understanding of eustatic vs. other factors in building sequences.

为PIs在纽约和新泽西边缘研究上白垩统至下古近纪和第四纪不整合面和地层格局提供了资金。要解决边缘地层学的两个独立但基本的问题：层序边界和地层不连续性是如何在海平面波动减少的时期形成的，以及为什么第四纪剖面没有与每次海平面旋回相关的不整合面。pi计划从该区域获取侧扫声纳图像，Chirp图像（用于海底浅层特征），MCS图像和vinracores。他们还将使用ODP站点1073作为年表。这些数据将提供高分辨率的物理地层学和精确的年代学，从而了解建筑序列中的起伏与其他因素。
