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.

我们对大洋中脊系统的分段模式的了解已经取得了相当大的进展，但对与分段相关的上地幔过程的性质和时间稳定性的了解却很少。将在大西洋中部海脊250公里宽的区域进行实地勘测，以获得水深测量覆盖范围，同时获取重磁数据。这些数据将允许检验与扩张中心的分段过程有关的脊线的时间演变的假设。这是一个美法合作的研究项目。
