9319324 Wysession This research will study the upper mantle, including subducting slabs, and the core-mantle boundary by means of a dense linear array of 20 broad-band PASSCAL seismometers installed from Missouri to Massachusetts, a distance of 1736 km. Data from earthquakes recorded by the array will substantially increase resolution of structures such as the core-mantle boundary under the Pacific, slab penetration depths in the Aleutians, Kuril-Kamchatka, Peru-Chile, and Central America, and the details of the upper mantle under North America and the Caribbean. This work should shed significant new insight into details of the earth's convection engine and resultant driving forces of plates and earthquakes. ***

9319324 Wysession这项研究将通过从密苏里州到马萨诸塞州安装的20个宽带密封地震仪的密集线性阵列来研究上地幔，包括俯冲板和核心掩体边界，距离为1736 km。 来自阵列记录的地震的数据将大大提高结构的分辨率，例如太平洋下的核心隐态边界，阿留申者，kuril-kamchatka，秘鲁 - 奇利奇和中美洲的平板穿透深度，以及北美和北美和驯鹿的上层披风的细节。 这项工作应该对地球对流引擎的细节以及板和地震的驱动力进行重大新的了解。 ***
