Collaborative Research: Imaging and Modeling Impact Generated Deformation at the Chicxulub Crater, Joint US/UK/Mexico Investigation and IODP Site Survey

该奖项是对奇克苏鲁布陨石坑近海部分的多通道地震调查。多道地震调查将被添加到一项由英国资助的断层摄影调查中，该调查将于2003年夏天在R/V莫里斯·尤因号上进行。多道地震勘探将绘制不受层析研究限制的特征，包括峰环的几何形状，以及峰环下可能的推覆边界。建模工作与多道地震剖面一起将确定冲击器的接近方向，并将撞击角度限制在10度以内。多道地震剖面连同层析数据将在两个拟议的IODP站点上完成所需的现场调查。

Award is for a multichannel seismic survey across the offshore portions of the Chicxulub impact crater. The multichannel seismic survey will be added on to a funded British tomographic survey that will be conducted in the summer of 2003 aboard the R/V Maurice Ewing. The multichannel seismic survey will map features that cannot be constrained by the tomographic study, including the geometry of the peak ring, and the possible thrust boundary beneath the peak ring. The modeling effort, together with the multichannel seismic profiles will determine the approach direction of the impactor and constrain the angle of impact to with 10 degrees. The multichannel seismic profiles together with the tomographic data will complete the required site survey over two proposed IODP sites.
