SGER: EarthScope--Texas Gulf Coast Pilot Study

我们提出了一个试点研究，包括六个三分量宽带站在墨西哥湾沿岸平原的一部分，已经有高质量的有源反射数据，一些老式的折射数据，并提出了一个地球物理模型进行测试，为期六个月的部署。 这一部署将使我们能够（1）应用，验证和微调接收器功能技术，用于成像深部沉积物下的地壳和上地幔，（2）测试为该地区提出的地球物理模型。 之所以需要进行这种试验性实验，有两个原因：* 为了了解大陆的演变，必须研究被动边缘和主动边缘，并调动不住在主动边缘附近的学生和公众的积极性;* 对被动边缘通常存在的厚沉积序列记录的被动数据应用地震分析技术存在困难。

We propose a pilot study consisting of a six-month deployment of six three-component broadband stations in a portion of the Gulf Coast Plain for which there is already high-quality active-source reflection data, some vintage refraction data, and a proposed geophysical model to be tested. This deployment will allow us to (1) apply, validate, and fine-tune receiver function techniques for imaging the crust and upper mantle beneath deep sediments and (2) test a geophysical model proposed for this region. The need for such a pilot experiment arises from two sources: * The importance of studying passive - as well as active - margins in order to understand continental evolution and to motivate students and the public who do not live near active margins; and * Difficulties in applying seismic analysis techniques to passive data recorded over thick sedimentary sequences, which typically exist in passive margins.
