Funds are recommended for a 3-year project to study the seismic and density structure beneath the Bermuda hotspot swell. A combined refraction and reflection seismic survey is planned for year 1 and analysis of the data in years 2 and 3. The study will try to address a fundamental question in geodymanics, i.e., what is the reason for large areal relief associated with some hotspot volcanics? The survey will determine what portion of the swell is supported by crustal underplating and how the existence of the underplating may have influenced the history of the vertical motion for Bermuda.

建议为一个为期3年的项目提供资金，以研究百慕大热点隆起下面的地震和密度结构。计划在第一年进行折射和反射地震综合调查，并在第二年和第三年进行数据分析。这项研究将试图解决地球动力学中的一个基本问题，即，与某些热点火山岩有关的大面积地形起伏的原因是什么？这项调查将确定哪一部分涌浪是由地壳底侵支撑的，以及底侵的存在如何影响百慕大垂直运动的历史。
