After the Tsunamis...
The images below on this page are my combinations of material published on the internet. For the individual image origins, see the citations. Because of continental drift, the position and orientation of the Chicxulub crater in Yucatán relative to other features has changed somewhat. Click on the image ABOVE to see my rendition "nuclear winter" beginning after the K-T asteroid hit. The toasted biosphere combined with vaporized continental material plus vaporized asteroid forms the smog. The ocean is roiled, boiled and scuzzy, as in my own rendition (Bryce 3D) above. The biospheres is to sooty mess in the sky, left by the wildfires that raged when the atmosphere reacted to the fireball of the shockwave and impacts. Yes, there is hard evidence for multiple impacts at 65 million years ago, which will be discussed after publication of a reevaluation of the KT impact event in the context of satellite data.
Tsunami Deposits and Ejected Materials, or why a 300 km diameter crater is not big enough to account for all the ejected material.
In contrast to the 2 to 3 cm thick clay layer found worldwide, the K-T boundary in the Gulf of Mexico region and in Haiti is composed of much thicker very coarse clastic deposits. Sand beds indicative of high energy deposition at the K-T boundary at Brazos River, Texas, have been interpreted to be the result of a major disturbance of the depositional environment, such as a tsunami approximately 50 to 100 meters high.
The page with larger images and a spherical map of gravitational anomalies is HERE (1.16 MB if you open them to full size). I took images mapped in Mercator projection (the original data) and mapped them Mercator to a sphere. Spherical mapping restores the original position of the concentric rings (bright purple) which center on the Chicxulub crater (yellow arrow BELOW RIGHT).
BELOW LEFT is the present day Earth showing the western hemisphere. Note the extensive ejecta on the Atlantic and Pacific plates. Cores from north of Hawaii have revealed chips of an asteroid (in the KT boundary material), indicating the forces and directions of much of the ejecta.
