Dear Jim, you asked: "Dewey, how much water was actually placed into
the atmosphere, and for how long a time was the hydrologic cycle
disrupted by the reduced vegetative cover and increased erosion?"
Re the water vapor injected into the atmosphere by the Chicxulub
impact, Pierazzo, Melosh, and Kring estimated 300 to 700 Gt in their
presentation "Estimates of climatically important gases released in
the Chicxulub Impact Event" at the Sudbury 1997, Large Meteorite
Impacts and Planetary Evolution meeting. Their paper can be read at:
For the duration of time that the hydrologic cycle was disrupted, I
have no idea. Perhaps the impact modelers on the list might provide
help on this topic.
