Maria,
That was quick!! I should've stuck around for the answer!!
If you need an expert on Antarctica ask Paul Ward (the guy who runs this place - I think!).
If you need to know anything about Antarctica then you have come to the best site on the net!! I used a lot of it for my class' research when I was teaching Antarctica. In fact, it was the kids who pointed me in the right direction. They were so fascinated by what they saw on this site that they told me about it! I'm still exploring the site myself and believe me when you read the stuff and visit the links you'll be amazed by what you see.
As far as teaching is concerned, I'm not sure what the rules in England are (I suspect that's where you are) but you may be able to enrol in a teaching degree somewhere. Ask Paul....he knows! That sounds so ominous....
Good luck
psr
