This is an investigation of the systematics of sedimentary sequence formation at Atlantic type margins; that is, the relationship between sea level change and sedimentary record at a subsiding basin margin. The goal is to be able to interpret seismically measured or determined sedimentary sequences in terms of: (1) correlatability with like sequences elsewhere and with a eustatic sea level curve, (2) improved determination of the amplitudes of eustatic sea level change, and (3) interpretation of sequences in terms of depositional environments. This modeling and analysis effort will consists of numerical modeling of sequences, analysis of the present day Pleistocene sedimentary and geomorphologic processes that are responding to glacioeustatic signals, and backstripping and reconstruction of the morphology of the Miocene sequences of the New Jersey shelf.

这是对大西洋型边缘沉积层序形成的系统学研究，即海平面变化与盆地边缘沉积记录之间的关系。目标是能够从以下方面解释地震测量或确定的沉积层序：(1)与其他地方的类似层序和海平面曲线的相关性，(2)改进海平面变化幅度的确定，以及(3)从沉积环境的角度解释层序。这项模拟和分析工作将包括层序的数值模拟、对现今更新世的沉积和地貌过程的分析，以及对新泽西州陆架中新世层序形态的回溯和重建。
