Broadband seismic imaging of lithospheric structure: Application to the Transantarctic Mountain Front and the Bentley Subglacial Trench

该奖项是为了支持地震实验-罗斯冰架（SERIS），这是一项对东南极洲和罗斯海湾之间板块边界的地震研究。第一年包括获取一条150公里长的多通道地震反射线，从罗斯冰架开始，通过一个出口冰川进入南极横贯山脉前缘。沿多道地震线将收集一条反向折射剖面和若干条广角反射剖面。第二年将进行数据解释、隆升和沉降弯曲建模、地震地层分析和重力建模。这项研究是俄亥俄州立大学、斯坦福大学、门洛帕克美国地质调查局和新西兰科学与工业研究部地球物理处（DSIR）科学家的联合项目。该合同支持建立一个12元短周期数字地震阵列，用于记录反射和折射镜头，以确定横贯南极山脉中部内陆部分的南极地壳厚度。该实验旨在作为未来十年在南极洲内部进行大规模地震实验的原型。

This award is in support of the Seismic Experiment-Ross Ice Shelf (SERIS), a seismic study of the plate boundary between East Antarctica and the Ross Embayment. The first year involves acquisition of a 150-km-long multichannel seismic reflection line starting on the Ross ice shelf and entering the Transantarctic Mountains front through one of the outlet glaciers. A reversed refraction profile and several wide-angle reflection profiles will be collected along the multichannel seismic line. Interpretation of the data, flexural modeling of the uplift and the subsidence, analysis of the seismic stratigraphy and modeling of gravity will be carried out in the second year. This study is a joint project between scientists from Ohio State University, Stanford University, the U.S. Geological Survey at Menlo Park, and the Geophysics Division, Department of Scientific and Industrial Research (DSIR) in New Zealand. This award supports the establishment of a 12-element short-period digital seismic array to record reflection and refraction shots to determine the Antarctic crustal thickness of a central inland portion of the Transantarctic Mountains. The experiment is designed to serve as a prototype for large-scale seismic experiments in the interior of Antarctica in the next decade.
