Here's more on 'Frozen Planet', via Wikipedia:
The seven-part series will focus on life in the Arctic and Antarctic. The production team were keen to film a comprehensive record of the natural history of the polar regions, because climate change is affecting landforms such as glaciers, ice shelves, and the extent of sea ice.
Filming is currently underway, and will focus particularly on the challenges facing polar bears and arctic wolves in the north and adelie penguins and wandering albatross in the south, although storylines are still being developed. After an introductory episode, the next four episodes will depict the changing seasons at the poles, before a final episode focusing on mankind’s activities there. Filmmakers will be working in new locations, including Antarctica’s active volcanoes and the Russian Arctic. Sequences already captured include migrating eider ducks and footage of a fur seal colony from the air. The aerial photography will again use the Cineflex and Gyron cameras pioneered on Planet Earth, which enable steady footage to be captured from long-range without disturbing the animals.
