Borehole seismic observations from the Chicxulub impact drilling: implications for seismic reflectivity and impact damage

Nixon, C. G.; Schmitt, D. R.; Kofman, R.; Lofi, Johanna; Gulick, Sean P. S.; Saustrup, S.; Christeson, Gail L.; Kring, David A. (David Allen); https://orcid.org/0000-0002-3440-6282 (AGU, 2022-02-21)

Seismic profiling over geological features reveal to us both the geometry of the structure and the speeds of the seismic waves within it. Calibrating these profiles using only data from the surface, however, remains ...
Drilling-induced and logging-related features illustrated from IODP–ICDP Expedition 364 downhole logs and borehole imaging tools

Lofi, Johanna; Smith, D.; Delahunty, C.; Le Ber, E.; Brun, L.; Henry, G.; Paris, J.; Tikoo, Sonia M.; Zylberman, W.; Pezard, P. A.; Célérier, B.; Schmitt, D. R.; Nixon, C. G.; Expedition 364 Science Party (Copernicus Publications, 2018-10-22)

In 2016 an international scientific expedition drilled a 1.3 km deep hole to explore the Chicxulub impact crater, buried below the surface of the Yucatán shelf (Mexico). This crater is linked to the End-Cretaceous mass ...
