9402033德特里克该项目继续开展多道地震和海底地震仪研究加勒特变换和南纬20度之间的南太平洋隆起的工作。将讨论的问题包括：(1)地震层2A底部P波速度快速增加的意义；(2)熔融透镜的物理性质；(3)轴向岩浆室下方中下地壳低速体积的大小和物理性质；(4)轴向区域的莫霍面；(5)跨重叠扩展中心的轴向地壳结构的变化。***
英文摘要
9402033 Detrick This project continues work on a multichannel seismic and ocean bottom seismograph study of the southern East Pacific Rise between the Garrett transform and 20 degrees south. Questions that will be addressed include: (1) the significance of the rapid increase in P-wave velocity at the base of seismic layer 2A, (2) the physical properties of the melt lens, (3) the dimensions and physical properties of the low velocity volume in mid and lower crust beneath the axial magma chamber, (4) the nture of Moho in the axial region, and (5) the variation in axial crustal structure across an overlapping spreading center. ***
