Velocity model navigation files (ASCII format) for the Chicxulub Crater area (96L676, 1996)

This data set presents the navigation data for two-dimensional seismic P-wave velocity models are derived from inversion of ocean bottom and land seismic data collected in the Chicxulub Crater area during 1996 R/V Longhorn cruise 96L676. A second vessel, GECO Sigma, fired airguns to the OBS and land seismometer instruments. The velocity model navigation files are in ASCII format and relate the model distance to (latitude, longitude) coordinates. The files contain three columns: Model distance along the profile (km); Latitude (degrees); Longitude (degrees). The data set was generated as part of the project called Structure of the Chicxulub KT Impact Crater, Yucatan, Gulf of Mexico, with funding from NSF award OCE94-15716.

本数据集展示了1996年R/V Longhorn巡航96L676期间在奇克舒鲁布陨石坑区域收集的海洋底部和陆地地震数据所逆推得到的二维地震P波速度模型的导航数据。第二艘船GECO Sigma向OBS和陆地地震仪发射气枪。速度模型导航文件采用ASCII格式，将模型距离与（纬度，经度）坐标关联。文件包含三列：沿剖面模型距离（公里）；纬度（度）；经度（度）。该数据集作为名为“尤卡坦湾墨西哥湾奇克舒鲁布KT撞击坑结构”的项目的一部分生成，该项目由NSF资助，资助编号为OCE94-15716。
