Antarctic crater

[Richard and Jo Cowen <cowen@blueoakfarm.com>]

OK, what's this about? First, it's science by poster session and  
press release (this one's from Ohio State). The research group found  
in a gravity survey a giant crater in the rock floor a mile under the  
Antarctic ice sheet. It's 300 miles across, apparently, which puts it  
into the mega-impact category, larger than Chicxulub. The rest is  
SPECULATION, because we have no data from the rocks. The researchers  
claim a connection with the Permo-Triassic impact. I wouldn't be  
surprised, but the evidence for the connection is just not there,  
even though a large part of the press release is devoted to it.

Cheers
