Chris, I looked up the abstracts for the Fall AGU. There are two of
them for this subject by searching under D. Abbott. The below link is
the main one. This is about the Indian ocean impact crater dated to
approx. 4800 yrs ago. (PP43B-1244)

The abstracts under L. Becker is about the impact craters dated to the
time of Younger-Dryas at 12900 yrs ago. I've always wondered about this
time period because of the large climate change.
