This post is dedicated to Stephen Sansom. Stephen, your dirty socks have been in my backpack since I picked them up off the beach nine months ago, and they’re here with me in Antarctica. I’ve made sure that they’ve had a good time, of course: visiting penguin colonies, hanging out on the bow of the ship, and going on adventures that I’m not even allowed to join. Below is a picture of your socks strapped to some oceanographic equipment, about to be sent 3,008 meters underwater. Don’t worry, they came back just fine. Later this afternoon they’ll set their little holey soles on an island that hasn’t even been seen since the 1980s.
