Ridge-Transform Response to Changing Plate Kinematics: An Investigation using Fracture Zone Geoid Waveforms

这是一个项目，以扩大PI的工作，分析 Seasat和Geosat大地水准面信号的断裂带小 南北大西洋的断裂带。 的 高度计数据将首先分解使用和经验 正交函数（Orthogonal Function，简称FEM）分析，并由此简化 数据集的形式和振幅的系统变化， 配置文件将被解释为各种模型， 可能与地壳变薄有关。 地壳变薄是 预计是不同大地水准面信号的主要原因 穿过小的偏移断裂带 %%% 断裂带是海底的一个基本特征。 它们代表板块边界的一部分， 岩浆沿沿着洋脊脊顶的分割过程。 不 关于脊-断裂带交叉点有很多了解， 在那里运作的物理过程。 分析将 在这个项目中进行的研究应该提供有用的信息， 关于海底的基本地质过程。

This is a project to extend the PI's work on analyzing Seasat and Geosat geoid signals of fractures zones to small offset fracture zones from the North and South Atlantic. The altimeter data will first be decomposed using and Empirical Orthogonal Function (EOF) analysis, and from this simplified data set systematic variations of form and amplitude of the profiles will be interpreted in terms of various models that may be related to crustal thinning. Crustal thinning is expected to be the main cause of different geoid signals across small offset fracture zones. %%% Fracture zones are a fundamental feature of the seafloor. They represent part of a plate boundary and may be control magma segmentation processes along ocean ridge crests. Not much is understood about ridge-fracture zone intersections and the physical processes that operate there. The analyses to be performed during this project should provide useful information regarding fundamental geological processes on the seafloor.
