Mantle Control of a Dynamically Evolving Spreading Center

这个项目的目标是测试几个想法 关于负责波峰的动态过程， 空间和时间变化的山脊几何上的缓慢， 南大西洋中等扩展率脊系统 从31号到36号。 该计划涉及两个船上腿， 进行地球物理研究，包括重力、磁力和 地震折射，沿着与Seabeam和疏浚。 舰载 该计划将遵循基于实验室的地球化学分析， 结果的三维数值模拟。 %%% 这是一个令人兴奋的项目， 调查人员正在试图对 脊顶部的基本突起。 多学科 方法是向前迈出的积极一步，研究的想法也是如此 地幔上涌等深部过程 在重力和地球化学方面的表面表现。

The objective of this project is to test several ideas concerning the dynamic processes responsible for cresting spatial and temporal variation in ridge geometry on the slow- intermediate spreading rate ridge system in the South Atlantic from 31 to 36 South. Program involves two ship board legs to conduct geophysical studies including gravity, magnetics, and seismic refraction, along with Seabeam and dredging. Shipboard program is to be followed by lab based geochemical analysis and 3 dimensional numerical modeling of results. %%% This is an exciting project from a first rate team of investigators who are attempting a very thorough study of fundamental processes at ridge crests. The multi-disciplinary approach is a positive step forward, as is the idea of studying deep seated process such as mantle upwelling in conjunction with their surface expression in gravity, and geochemistry.
