Under-Sea-Ice Observation Tube at McMurdo Station, Antarctica

Video of the ocean beneath the sea ice at McMurdo Station, Ross Island, Antarctica. I included a bit of the hike out towards the Observation Tube just to give people a bit of a view for what it's like walking around station, but I don't have access to high-quality video equipment or editing software in the field-- skip to 1:52 if you'd like to focus on the Ob-Tube without most of the camera shake during the walk to get there. The Ob-Tube had great views of brinicles (explained in the video) and the sounds of seals chirping underwater. It was beautiful! **Make sure your video quality is set to HD (720p) in order to read the text embedded in the video that explains the process of brinicle formation.
