Which Way Do We Go From Here?

Hard to believe in one month I will be on my way to the bottom of the Earth. Here is a link of a live web cam of King George Island where the Antarctica Marathon will take place.

Sun rise is 4:39 and sunset is at 21:39
Temperature is around -2°. 
I'm assuming this is Celsius, which would be around 28° F. 
A nice winter day in Minnesota.

Not sure if I should be excited or nervous. My students have been asking some interesting questions:
What happens if the ship sinks?
What happens if you get attacked by a sea lion, whale or penguin?
What happens if the ship gets frozen in and stuck in the ice?

They have me wondering...hmmmm
