I must alert you to the blog of my friend, writer and artist Claire Beynon who is blogging about her trip to Antarctica. For even more info. the writer Vanda Symon, in her excellent blog, writes in detail a great introduction to Claire's endeavours.
I have also added a link to the Dr Sam Bowser's blog (you'll also find it under Things Conservational in my sidebar.) He is also working down there at the moment and it is through him that Claire has been able to go down and wonderfully 'create'.
