Back from the Arctic

My arctic expedition is now over, and despite the jetlag lingering, I've had time to process most of my thousands of photos. The highlight of the whole trip, and the most wondrous scene I've ever witnessed was the appearance of the northern lights. Here are some photos I took from off the coast of Alaska. Luckily the conditions were dead calm, otherwise the long exposure (8 seconds) would have resulted in blurriness.
