9629018 Wysession The P.I.'s research involves using seismology to map the interior of the Earth, and interpreting these maps to understand the big picture of what our planet is made of and how it works. Just as medical doctors use a sonogram or CAT-scan to image a patient, he uses the reflecting and refracting waves from large earthquakes to image the Earth. This most significant contributions have come through the mapping of the highly variable boundary between Earth's core and mantle, half-way to the center of our planet. This information has helped change the ways geologists perceive the dynamic processes at work inside the Earth. Over the next five years he will continue to develop his research program in the mapping of Earth structure in several directions. He will concentrate on the core-mantle boundary region, but will examine other regions of the Earth, including the Earth's core, the olivine phase transitions at depths of 410 and 660 km, and the upper mantle structure beneath spreading plate boundaries.

小行星9629018 私家侦探的研究涉及使用地震学来绘制地球内部的地图，并解释这些地图，以了解我们的星球是由什么组成的，以及它是如何工作的。 就像医生使用超声波或CAT扫描来给病人成像一样，他使用大地震的反射和折射波来给地球成像。 这一最重要的贡献来自于对地核和地幔之间高度可变的边界的测绘，这一边界位于我们星球中心的一半。 这些信息有助于改变地质学家对地球内部动态过程的看法。 在接下来的五年里，他将继续发展他的研究计划，在几个方向绘制地球结构。 他将专注于核幔边界区域，但将研究地球的其他区域，包括地球的核心，在410和660公里深处的橄榄石相变，以及扩张板块边界下的上地幔结构。
