The study will focus on an important problem concerning the oceanic crustal structure, i.e., the extent to which seismic boundaries within the crust correlate with geological boundaries. It aims to link the seismic structure of upper oceanic crust with the known geology of the crust exposed at Hess Deep and the Blanco Transform areas. The PIs hope that the experiment will clarify the relationship between the seismic boundaries and the geologic units of oceanic crust. Two separate cruises will be undertaken to conduct refraction profiling with wide-angle MCS lines allowing high-resolution imgaging of the uppermost crust.

该研究将重点关注与海洋地壳结构有关的一个重要问题，即地壳内的地震边界与地质边界的关联程度。 它的目的是将上洋地壳的地震结构与赫斯深海和布兰科变换区域暴露的地壳的已知地质联系起来。 PI们希望该实验能够澄清地震边界与洋壳地质单元之间的关系。 将进行两次独立的巡航，利用广角 MCS 线进行折射剖面分析，从而对最上层地壳进行高分辨率成像。
