This report provides information on the University of Texas, Institute for Geophysics (UTIG) led ECORD (European Consortium for Ocean Research Drilling) geophysical and geotechnical hazard site survey offshore Yucatan aboard the R/V Justo Sierra which took place from the 16th April to the 23rd April 2013 over a study area within the Chixculub impact crater. The cruise has been carried out under contract for ECORD comprising the acquisition of geophysical data (surface tow boomer, side scan sonar, multibeam echosounder, magnetometer and CHIRP data) and geotechnical data (cone penetrometer tests (CPT)), ahead of scheduled ECORD led drilling of the Chixculub impact crater. The survey was undertaken in joint collaboration between UTIG and Universidad Nacional Autonóma de México (UNAM). Seafloor Geotec, LLC, was commissioned to carry out CPTs at selected sites within the survey area.
