Global Sea Level and Late Cretaceous to Miocene Sequences: Completion of the New Jersey Coastal Plain Drilling Project

在1987年至1992年之间的一系列会议上，学术界形成了一种共识，即过去海平面上升变化的时间和幅度及其与地层层序的关系应该通过在被动边缘钻孔样带来确定。他们确定了三个关键的时间间隔：渐新世到最近的“冰窖世界”，在这段时间里，冰川作用明显发生了变化；白垩纪的“温室世界”，显然缺乏重要的冰盖；古新世-始新世的“双屋世界”，关于冰盖存在的争论仍在继续。为了解决序列和海平面变化的问题，P.I.s设计了“新泽西海平面样带”，作为一系列钻孔，从新泽西州海岸平原的陆上穿过大陆架到斜坡和上升。新泽西海平面样带是评估全球海平面与被动大陆边缘序列之间关系、确定海平面变化的时间和幅度以及评估海平面变化机制的全球运动的第一步。陆上部分，即新泽西州沿海平原钻井项目，已经在Island Beach、Atlantic City、Cape May和Bass River完成了4个井眼。该项目是为了完成NJ海岸平原钻井项目，在NJ的Corson's Inlet钻一个2000英尺的井眼，在NJ的Parvin钻一个1200英尺的井眼。＊＊＊

Three crucial time intervals were identified: the Oligocene to Recent "Icehouse World," when glacioeustatic changes were clearly operating; the Cretaceous "Greenhouse World," which apparently lacked significant ice sheets: and the Paleocene-Eocene "Doubthouse World," a time for which debate continues over the existence of ice sheets. To address sequences and sea-level changes, the P.I.s designed the "New Jersey Sea Level Transect" as a series of boreholes from the onshore NJ Coastal Plain across the shelf to the slope and rise. The New Jersey Sea Level Transect is the first step in a global campaign to evaluate relationships between global sea level and passive continental margin sequences, to determine the timing and amplitude of sea level variations, and to evaluate mechanisms of sea level change. The onshore component, the NJ Coastal Plain Drilling Project, has completed 4 boreholes at Island Beach, Atlantic City, Cape May, and Bass River. This project is for the completion of the NJ Coastal Plain Drilling Project by drilling a 2000 ft borehole at Corson's Inlet, NJ and a 1200 ft borehole at Parvin, NJ. ***
