Tomorrow I head back to Antarctica for another month, working as a photography guide and lecturer aboard the m/v Ocean Diamond with Quark Expeditions. Here's a stunning iceberg we observed earlier this season, at the Ukrainian Vernadsky Research Base on the Antarctic Peninsula. In 47 expeditions to the Polar Regions, I've seen a lot of icebergs, but this one stood out to me - the shape, the height (it was massive), and the dark clouds behind. What's more, the Ukrainians were amazing hosts and even opened their bar for us, where they serve home-made vodka.
