This is a project to collect high-resolution multichannel seismic data in the Sandino forearc basin offshore Nicaragua. The data will be used to determine if a eustatic sea level signal can be discerned near a plate boundary. The data will be used to test the hypothesis that tectonic effects can be identified and distinguished by acquiring multichannel seismic data that define unconformities and sequences that can be correlated with coeval sequences from other margins and with the deep-sea oxygen isotope record proxy for sea-level change. This project will tackle the important problem of separating the records of tectonic effects and eustasy on an active margin. If successful, it may be possible to extract eustatic records from other active margins, thereby improving our understanding of global sea level change.

这是一个在尼加拉瓜近海桑迪诺弧前盆地收集高分辨率多道地震数据的项目。这些数据将被用来确定是否可以在板块边界附近辨别出海平面升降信号。这些数据将用于检验一种假设，即可以通过获取多通道地震数据来确定和区分构造效应，这些数据确定了不整合面和层序，这些不整合面和层序可以与来自其他边缘的同时代层序以及深海氧同位素记录的海平面变化代用指标相关联。该项目将解决分离活动边缘的构造效应和地壳运动记录的重要问题。如果成功，就有可能从其他活动边缘提取海平面变化记录，从而提高我们对全球海平面变化的理解。
