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PI提供资金，以研究纽约和新泽西边缘的上白垩纪至下古近纪和第四纪不整合面和地层模式。 两个独立的，但根本的问题，地层的边缘是要解决的：如何形成层序边界和地层不连续性减少海平面波动的时间，以及为什么第四纪部分没有与每个海平面周期的不整合。 PI计划获取该地区的侧扫声纳图像、Chirp图像（海底浅层特征）、MCS图像和vinracore。 他们还将使用ODP站点1073进行年表。 这些数据将提供一个高分辨率的物理地层学和精确的年代学，从而了解海平面与其他因素在建设序列。
