Two-dimensional seismic velocity data (netCDF grid format) for the Chicxulub Crater area (EW0501, 2005)

These two-dimensional velocity models are derived from full-waveform inversion of multichannel seismic data collected in the Chicxulub Crater area during 2005 Ewing cruise EW0501 (chief scientists Sean Gulick and Penny Barton). The data files are in GMT-compatible netCDF grid format with grid parameters as follows: X values are distance in km along profile; Y values are depths in km below the sea surface; Z values are P-wave velocities in m/s. The data set was generated as part of the project called Chicxulub impact effects and the recovery of life using scientific drilling investigations at ground zero. Funding was provided from NSF award OCE17-37351.

本二维速度模型系通过对2005年Ewing巡航EW0501期间于奇克休卢布陨石坑区域采集的多道地震数据进行全波形反演所得。数据文件采用GMT兼容的netCDF网格格式，其网格参数如下：X值代表沿剖面距离的公里数；Y值代表海面以下深度的公里数；Z值代表P波速度的米每秒。该数据集系作为名为“奇克休卢布撞击效应及利用地面零点科学钻探调查恢复生命”项目的一部分而生成。项目资金由美国国家科学基金会（NSF）颁发的OCE17-37351号奖项提供。
