yes, explicitly. He was a major part of the discussion.

Mike and I get on quite well, in fact. He knows more than anyone else the problems with water models. He doesn't accept that my models are better, but he accepts that I have argued them convincingly.

Nathalie Cabrol is here at the conference and I'm not sure if she sat through the discussion, but I think so.

Gilmorte and Phillips, I'm not sure at all. I don't know them by sight.

Again, they are on for 16:25 this arvo, so, Im'sh'alaah, I'll hear their talk, but I have problems with any gully forming model based on subsurface liquids of any nature (not even CO2!).

Surface melt is the go, imho...
