High-resolution reflection profiles totalling over 639 kilometres imaged the topography of the Cretaceous-Tertiary boundary within the crater to determine its structure. Deeper targets of this profiling included: mega-terraces and slumped blocks that collapsed into the excavated transient crater, pre-impact layered sedimentary rocks, and structures within the basement that were disrupted by the catastrophic event. Thirty-three deployments of ocean-bottom seismometers and 99 land-based seismic stations recorded the airgun shots used for the marine profiling to produce closely spaced travel-time records
