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.

奖项是在Chicxulub Impact火山口的近海部分进行的多通道地震调查。 多通道地震调查将添加到一项资助的英国层析成像调查中，该调查将于2003年夏季在R/V Maurice Ewing上进行。多通道地震调查将绘制无法通过断层扫描研究来限制的特征，包括峰环的几何形状以及峰环下方的可能推力边界。 建模工作以及多通道地震曲线将确定冲击器的进路方向，并以10度的限制对冲击角度约束。多通道地震曲线以及层析成像数据将在两个提出的IODP站点上完成所需的站点调查。
