One of the perks of working at the Smithsonian is the amazing people we meet on a daily basis. Michael Lang, the Study Leader for our Antarctica trip, definitely leads the pack. As the Smithsonian Scientific Diving Officer, he directs one of the nation’s largest civilian scientific diving programs. Lang's fascinating job takes him all over the world, to waters both cold and warm. Here, he talks about dipping into the seas off Antarctica, into an underwater world few might ever experience.
