Shot navigation for CHIRP SEG-Y sub-bottom data from the All-American Canal near Calexico, CA, April 2019
ASCII files with navigation information for each shot of the CHIRP SEG-Y data collected in the All-American Canal. The purpose of these data was to image deformation features in shallow sediments in the Imperial Fault system and surrounding regions, to understand strain partitioning and identify locations for geologic slip rate studies. Navigation data were collected with a Septentrio Altus NR3, pole-mounted on the CHIRP floating frame. The sample rate was 1Hz which provides sub-meter positioning. Elevations in the files are corrected to the instrument. These ASCII files contain six columns: Shot number, Longitude, Latitude, Elevation in meters, UTM X, UTM Y. UTM zone is 11N. Funding was provided by the Southern California Earthquake Center (SCEC), grant #18119.
