“Frozen Planet” is the latest nature series from the makers of “The Blue Planet” and “Planet Earth.” This newest offering is narrated by Alec Baldwin and will air on the Discovery Channel in seven parts, focusing on life and the environment in both the Arctic and Antarctic areas.

In the preview video above, playful polar bear cubs ruin a hunt for their mama, while in the video below, a brinicle, or brine icicle, plunges off its ice shelf to the Antarctic seabed, destroying everything in its path.

The premiere episode is titled “To the Ends of the Earth” and features polar bears battling each other for mates; surfing penguins; and orcas who hunt in a well-orchestrated group for seals. It premieres Sunday night (March 18) at 8 p.m. ET/PT on Discovery.
