Whether you’re intrigued in the chilling poles or the warm Great Barrier Reef, two new documentary series are highlighting these ecologically-fragile locations.

Frozen Planet brings to life the frozen wildernesses of the Artic and Antarctica. We particularly enjoyed the “Unexpected encounters” episode where orcas were seen surfacing mere feet from videographers.

If you’re more inclined to a passion for reefs and their species, then you can’t miss the new Great Barrier Reef documentary produced by Australia’s Channel Nine and the BBC.

You can watch the episodes on the BBC or Channel Nine websites, respectively, or purchase them on iTunes here.
