[402364]在这个项目中,PI将进行实地研究,测量Jaramillo/Matuyama边界与Blanco悬崖和邻近海底相交处的地壳磁化强度。他将逐步提高测量的分辨率,通过重复测量相同的样条,使用表面磁测量深拖测量,然后最后的阿尔文测量。本研究的主要目的是确定海洋磁异常的来源。该研究还将对海洋地壳起源的时间维度提供约束。* * *
英文摘要
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. ***
