AbstractOPP-99-05790MillerIn 1994, two deep seismic reflection profiles that image the entire crust across the continental junction between North America and Euraisa were acquired with National Science Foundation support. They provide a unique crustal section which goes across an entire continent created by the major convergent tectonic processes that operated during the Mesozoic and Cenozoic. A full interpretation of the deep seismic data must be processed and a structural contour map of the acoustic basement along the transect must be made. A geologic and tectonic interpretation of the transect had been planned for the centerpiece of a Geological Society of America (GSA) Special Paper on the Bering Sea, but the graduate student who was supposed to do the interpretation and make the structural map did not do the work. The Geology Department at Stanford University has a post-doctoral research affiliate who is currently available to make the full interpretation. NSF support has been requested to complete the interpretation of the seismic reflection profiles before the Bering Sea GSA Special paper is published in the summer of 1999.

米勒1994年，在美国国家科学基金会的支持下，获得了两个深地震反射剖面，它们对横跨北美和欧亚大陆交界处的整个地壳进行了成像。 它们提供了一个独特的地壳剖面，横跨整个大陆，这是由中生代和新生代的主要会聚构造过程造成的。 必须对深层地震数据进行全面的解释，并绘制沿剖面沿着声学基底的构造等值线图。 美国地质学会（GSA）曾计划将对该断面的地质和构造解释作为白令海专题论文的核心内容，但应该进行解释并绘制结构图的研究生没有完成这项工作。 斯坦福大学地质学系有一名博士后研究人员，目前可对这些资料进行全面解读。 已要求国家科学基金会提供支助，以便在1999年夏季出版白令海全球海洋事务局特别文件之前完成对地震反射剖面的解释。
