Understanding the history, cause, and impact of sea level fluctuations is a compelling goal of Earth system research. Not only are worldwide effects of encroaching shorelines evident today-the rate of this change is clearly increasing. Whereas global sea level rise during the previous century was ~1.8 mm/y (Church and White, 2006), today that rate is ~3.25 mm/y (Cazenave et al., 2009), in part due to anthropogenic influences (Barnett, 1990). Furthermore, in many coastal regions the rate is still higher because of the additional effect of local subsidence. The geologic record shows that global sea level has fluctuated by well over 100 m (summaries in Donovan et al., 1979) at rates as high as 20-40 mm/y (Fairbanks, 1989; Stanford et al., 2006). The New Jersey margin in general is an ideal location to investigate the Cenozoic history (last ~50 million years) of sea-level change and its relationship to sequence stratigraphy for several reasons: -,Rapid depositional rates. - Tectonic stability. - Well-preserved, cosmopolitan fossils suitable for age control characterize the sediments of this margin throughout the time interval of interest. - There exists a large set of seismic, well log, and borehole data with which to frame the general objectives and choose appropriate drill sites.

了解海平面波动的历史、原因和影响是地球系统研究的一个引人注目的目标。今天，侵蚀海岸线的全球影响不仅是显而易见的，而且这种变化的速度显然正在增加。上个世纪全球海平面上升约1.8毫米/年(丘奇和怀特，2006年)，而今天海平面上升速度约为3.25毫米/年(Cazenave等人，2009年)，部分原因是人为影响(Barnett，1990)。此外，在许多沿海地区，由于局部下沉的额外影响，这一比率仍然较高。地质记录表明，全球海平面以高达20-40毫米/年的速度波动了超过100米(Donovan等人，1979)(费尔班克斯，1989；Stanford等人，2006年)。总体来说，新泽西边缘是研究新生代海平面变化历史(过去约5000万年)及其与层序地层学关系的理想地点，原因有几个：-，快速沉积速率。--构造稳定。-保存完好、适合于年龄控制的世界性化石是整个感兴趣的时间间隔内这一边缘的沉积物的特征。-有大量的地震、测井和井眼数据，可用来确定总体目标和选择合适的钻探地点。
