The Missouri to Massachusetts Broad Band Seismometer Deployment: Collaborative Studies of Mantle Structure

小行星9315825 这项研究将利用从密苏里州到马萨诸塞州距离1736公里的20个宽带PASSCAL地震仪密集线性阵列研究上地幔，包括俯冲板块和核幔边界。 该阵列记录的地震数据将大大提高结构的分辨率，如太平洋下的核幔边界，阿留申群岛，千岛-堪察加半岛，秘鲁-智利和中美洲的板渗透深度，以及北美和加勒比地区上地幔的细节。 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。 ***

9315825 Clarke 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. ***
