This study actually consists of two research programs. The first, and probably most important, is an attempt to corroborated the possibility that the maximum sediment thickness in the Bengal basin exceed 22km, rather than the 16km generally cited. The second is the study of two aseismic ridges aligned about N.S in the Bay of Bengal, the Ninetyeast Ridge and the 85 E Ridge. Existing magnetic and seismic reflection data will be combined and extended with gravity network to understand the state of isostasy in the region.

这项研究实际上由两个研究项目组成。第一个，也可能是最重要的，是试图证实孟加拉盆地最大沉积物厚度超过 22 公里，而不是通常引用的 16 公里的可能性。第二个是对孟加拉湾北纬两个地震脊的研究，即九十东脊和 85 东脊。 现有的磁和地震反射数据将与重力网络相结合和扩展，以了解该地区的均衡状态。
