9402364 Tivey In this project the PI will conduct a field study to measure magnetization of the crust where the Jaramillo/Matuyama boundary intersects the Blanco scarp and of the adjacent seafloor. He will do this by progressively increasing the resolution of measurements through repeat surveying of the same transect using surface magnetic measurements to deep-tow measurements and then finally ALVIN measurements. The primary purpose of this study is to determine the source for marine magnetic anomalies. This study will also provide constraints on the time dimension of the origin of oceanic crust. ***

小行星9402364 在本项目中，PI将进行实地研究，以测量Jaramillo/Matuyama边界与布兰科陡崖相交处的地壳和邻近海底的磁化强度。 他将逐步提高测量的分辨率，通过使用表面磁测量对同一断面进行重复测量，然后进行深拖测量，最后进行ALVIN测量。 这项研究的主要目的是确定海洋磁异常的来源。 这项研究还将对洋壳起源的时间维度提供限制。 ***
