0092744MorozovThis grant provides one fourth support of the costs of acquiring digital data sets for nine deep seismic sounding (DSS) profiles from the Center GEON in Moscow. The other 3/4 of the costs will be borne by the Defense Threat Reduction Agency (DTRA). The Russian DSS data sets are a truly unique source of seismic data which image the upper mantle structure below a large fraction of the Eurasian continent. These data sets are unique in that they were produced using well controlled and powerful seismic sources, i.e. peaceful nuclear explosions (PNE) equivalent in size to M 5 earthquakes and chemical explosions. Nine continental transects were produced using over 20 PNEs and 300 chemical explosions recorded at over 200 sites. These data contain structural information about the Earth's interior in the intermediate depth range (0-3200 km) between what can be learned from earthquake seismology and conventional controlled source seismology. In addition, these are data sets that are likely never to be reproduced. The data sets will be digitized and quality-controlled by Center GEON scientists in Moscow, transferred to University of Wyoming scientists for further QC, and finally reformatted and delivered to the IRIS Data Management Center where the data will be freely accessible to all interested academics scientists. The project should be complete in four years.***

这笔赠款为从莫斯科Geon中心获取九条深度地震测深(DSS)剖面的数字数据集提供了四分之一的支持。另外四分之三的费用将由国防威胁削减局(DTRA)承担。俄罗斯的DSS数据集是一个真正独特的地震数据来源，这些数据成像了欧亚大陆很大一部分下面的上地幔结构。这些数据集的独特之处在于，它们是利用控制良好的强大震源产生的，即规模相当于5级地震和化学爆炸的和平核爆炸(PNE)。在200多个地点记录了20多次PNES和300次化学爆炸，产生了9个大陆横断面。这些数据包含了介于地震地震学和常规可控震源地震学之间的中等深度范围(0-3200公里)的地球内部结构信息。此外，这些数据集可能永远不会被复制。这些数据集将由莫斯科的Geon中心科学家进行数字化和质量控制，然后转移到怀俄明大学的科学家进行进一步的质量控制，最后重新格式化并交付给IRIS数据管理中心，所有感兴趣的学术科学家都可以在那里免费获取数据。该项目将在四年内完成。*
