Seabeam Investigation of the Mid-Atlantic Ridge Between 24 Degrees North and 30 Degrees 40' North and SeaMARC II Investigation of the Australian-Antarctic Discordance

这一更新将支持对1988年三个实地计划期间收集的地球物理数据进行额外一年的研究。这些野外计划产生了丰富的数据集，这些数据是关于沿中间扩张的东南印度洋海脊和缓慢扩张的中大西洋海脊的地壳增长过程。更新将有助于进一步分析这些扩散中心的火山构造特征，以及进一步处理磁力和重力数据集。

This renewal will support an additional year of study of the geophysical data collected during three field programs in 1988. These field programs have produced rich data sets about crustal accretionary processes along the intermediate-spreading Southeast Indian Ridge and the slow-spreading Mid-Atlantic Ridge. The renewal will support further analysis of the volcano-tectonic characteristics of these spreading centers as well as for further processing of the magnetic and gravity data sets.
