[Flotsam]

It's what I heard on the news but don't know if true or not. Two bodies recovered today from inside.

I suggested cave divers after the Herald of Free Enterprise sinking. Glad to hear the message finally got through!

Apparently 11 of the 22 divers involved are cavers. They have located 5 of the missing 6 bodies, including the owner, his daughter and the chef:

Would they be diving on air to 50m? Nitrogen narcosis could be an issue. Another issue would be multiple decompression dives. I think things get complicated with rest periods etc.

They absolutely will not be using air at 50m

From sky news:
"Divers involved in the search and rescue operation for the sunken Costa Concordia in 2013 have been called in to stretch the amount of time underwater to 20 minutes per dive. For the past two days, a major challenge for divers had been their limit of 12 minutes on each dive, including the time to go down and come back up.

But the Costa Concordia divers have cylinders containing particular micelles which allow for a longer dive.

I would assume such a search & recovery effort would call for rebreathers? (Not a diver myself.) Quite interesting to hear that cave divers were called upon for the search.
