A SeaMARC II Investigation of the Mid-Atlantic Ridge

该项目是为了支持一个实地项目， 大西洋中脊（MAR）24至29度的构造 北纬 主要工具是SeaMARC II，这些数据 将辅以重力和磁力数据。 连续 轴向不连续面和构造地貌的覆盖范围 变化沿着裂谷在至少100 公里将被获得。主要目的是了解 火山和构造活动的变化沿着缓慢的 扩散中心，小的轴向不连续性的性质， 抵消了MAR，以及导致 分割的MAR。拟议的研究代表了 SeaMARC II在大西洋的首次使用。 这是一个重要 研究，因为它将允许在形态学之间进行比较， 和构造的缓慢和快速扩张的山脊使用SeaMARC II工具。

This project is to support a field program to study the tectonics of the Mid-Atlantic Ridge (MAR) from 24 to 29 degrees North latitude. The principal tool is SeaMARC II, and these data will be complemented by gravity and magnetics data. Continuous coverage of the axial discontinuities and the morphotectonic variations along the rift valley over a distance of at least 100 km will be obtained. The main objective is to understand the variations in volcanic and tectonic activity along a slow spreading center, the nature of small axial discontinuities that offset the MAR, and the mantle processes that lead to segmentation of the MAR. The proposed research represents the first use of SeaMARC II in the Atlantic. This is an important study because it will allow a comparison between the morphology and tectonics of slow and fast spreading ridges using the SeaMARC II tool.
