The PI will perform a tomographic analysis and wide-angle migration of marine shots recorded by receivers onshore and offshore Yucatan to study the structure of the Chicxulub impact crater. The analysis could provide new constraints on aspects of the central structure of the impact crater, e.g., deep basement uplift and position of the Moho underneath, obliquity of the impact, and geometry and volume of the impact melt sheet. This is a joint project between University of Texas at Austin and Imperial College, London.

PI将对尤卡坦半岛陆上和近海接收器记录的海洋拍摄进行层析成像分析和广角偏移，以研究希克苏鲁布撞击坑的结构。分析可以对撞击坑中心结构的各个方面提供新的限制，例如，深部基底隆起和下方莫霍面的位置、撞击的韧性、撞击熔融岩片的几何形状和体积。这是得克萨斯大学奥斯汀分校和伦敦帝国理工学院的一个联合项目。
