9315971 Fischer 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. ***

9315971 Fischer 这项研究将通过从密苏里州到马萨诸塞州（距离 1736 公里）安装的 20 个宽带 PASSCAL 地震仪的密集线性阵列来研究上地幔，包括俯冲板片和核幔边界。 该阵列记录的地震数据将大大提高结构的分辨率，例如太平洋下的核心-地幔边界、阿留申群岛、千岛堪察加半岛、秘鲁-智利和中美洲的板片穿透深度，以及北美和加勒比海下上地幔的细节。 这项工作将为地球对流引擎的细节以及板块和地震的驱动力提供重要的新见解。 ***
