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

9315825克拉克这项研究将通过从密苏里州到马萨诸塞州安装20台宽带PASSCAL地震仪的密集线性阵列来研究上地幔，包括俯冲板块和核幔边界，距离为1,736公里。该阵列记录的地震数据将大大提高对以下结构的分辨率：太平洋下的核-地幔边界、阿留申群岛、千岛-堪察加群岛、秘鲁-智利和中美洲的板块穿透深度，以及北美和加勒比地区的上地幔细节。这项工作应该会对地球对流引擎的细节以及板块和地震的综合驱动力有重要的新见解。***

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. ***
