I had an opportunity last night to watch the original Netflix ‘Frozen Worlds’ walrus episode and have some addition thoughts.
One big eye-opener was the final shot of the walrus sequence: a polar bear approaching from the water to feed on the carcasses below the cliff at Cape Kozhevnikov. This is additional proof that polar bears were in the area while the crew were filming. Yet the narrative in the film was silent on the risk to walruses on the cliff from polar bears and not a word was spoken of the hundreds of walruses that had fallen off that very cliff just days before after being spooked by approaching bears.
Oddly, I have also discovered that the Russian scientific advisor to the film, Anatoli Kochnev, wrote a scientific report in 2002 (translated into English) on walrus deaths at two regularly used beach haulouts on Wrangel Island from 1989-1996, when walrus population numbers were much lower than today and summer sea ice extent was higher (Kochnev 2002). He concluded that stampedes initiated by polar bears were responsible for most of the walruses found trampled to death.
This means Kochnev knew that polar bears nearby were a huge risk factor for walrus stampedes over the cliff but went along with the official ‘Our Planet’ narrative that no polar bears were involved and only lack of sea ice and poor eyesight were to blame for the carnage presented in the Netflix film.
