I vaguely remember an incident where the authorities used an artificial ice surface (skating rink or curling rink, I can't remember) as a temporary morgue. It was some sort of natural disaster in high summer. The artificial ice gave the coroner and law enforcement time to identify the victims and release them to families for proper burial.

I seem to recall that various teams in Haiti after the earthquake used Tiger Balm instead of Vicks to mask the smell of death. I can't say I've tried it. I hope I don't ever have to.

EDIT:
This is OT but it may be of interest. The link is to the cards listing the descriptions, effects, and possible identifying information for the recovered remains of people drowned in the sinking of the Titanic. I wonder if the cold, cold Atlantic water slowed decomposition enough to help the officials trying to identify the bodies? At any rate, it is a fascinating read.
