Collaborative Research: New Tools Applied to a Classic Problem: Towards an Understanding of What Shapes the Stratigraphic Record at Passive Margins

为研究纽约和新泽西边缘的上白垩统至下古近纪和第四纪的不整合和地层模式的PI提供了资金。要解决边缘地层学的两个独立但基本的问题：层序界面和地层不连续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个海平面旋回相关的不整合。PIS计划从该地区获取侧扫声纳图像、Chirp图像(用于海底浅层特征)、MCS图像和矿藏。他们还将使用ODP1073站点进行年表。这些数据将提供高分辨率的物理地层学和精确的年代学，从而了解海平面与建造层序中的其他因素。

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.
