9416630 Small Data collected in 1993 on the Mid-Atlantic Ridge north of the Bouvet triple junction will be used to study the factors contributing to the disappearance of the axial valley and the interaction of the ridge with the proposed Shona hotspot. The objectives are to determine the tectonic history of the ridge segment, explain the variation in axial morphology, produce a Bouguer anomaly map, and integrate the geophysical data with geochemical results to better understand the influence of the proposed Shona hotspot on the ridge.

9416630将利用1993年在布维三重交界处以北的大西洋中部海脊收集的小数据，研究造成轴谷消失的因素以及海脊与拟议的肖纳热点之间的相互作用。其目的是确定海脊段的构造历史，解释轴向形态的变化，制作布格异常图，并将地球物理数据与地球化学结果结合起来，以更好地了解拟议中的肖纳热点对海脊的影响。
