s01e04 — Frozen Seas

It's stunningly beautiful how penguins jump ashore, like shots from a cannon. It's hard to even believe that they are doing this on their own, and not under the influence of some external force!

The stories of whales trapped in the ice are absolutely heartbreaking.

What a harsh and huge frozen wasteland, but wasteland is not a particularly suitable word, because life goes on in the snow in unbearable conditions anyway.
An interesting series
