A Geophysical Investigation of the Mid-Atlantic Ridge Off Axis Using Hydrosweep

我们在理解 分割模式的洋中脊系统，但很少有 了解了上层建筑的性质和时间稳定性， 地幔过程与分割有关。了实地调查 将在大西洋中部250公里宽的区域进行 利用Hydrosweep获取水深覆盖范围，沿着 重磁数据采集。这些数据将允许 检验有关海脊时间演变的假设 与传播中心的分割过程有关。这是 一个美法合作研究项目。

There has been considerable progress in our understanding of the segmentation patterns on mid-ocean ridge system, but little has been learned about the nature and temporal stability of upper mantle processes associated withthe segmentation. A field survey will be carried out over a 250 km wide area of Mid-Atlantic Ridge using Hydrosweep to obtain bathymetric coverage, along with acquisition of gravity and magnetic data. These data will allow testing of hypotheses concerning temporal evolution of the ridge related tosegmentation processes of the spreading center. This is a US-France collaborative research project.
