Article Summary:

BBC Natural History Unit producer Kathryn Jeffs has written an article about the making of the amazing time-lapse footage that documents the formation of a brinicle under the ice in Antarctica. On the BBC Nature pages, she describes how on their first attempt, after leaving the camera and lights in place overnight, a seal had knocked the camera over and rendered the footage useless. The next attempt produced the footage that was eventually used in the Frozen Planet series. The shot needed : “Three underwater tripods, three underwater lighting stands, three cameras, three lights, two control boxes, and countless cables which were all placed and held down with lead weights” under the ice in 2°C water.
