Headline Tag: Animals Rating: Amazing Hits: 295 Comments: 2 The Blue Planet: The Deep The Blue Planet: The Deep Broadcast September 2001, this program explores the unknown depths of the ocean. RT 48:40. Over 60% of the sea is more than a mile deep and it forms the planet's most mysterious habitat. A sperm whale descends 1,000 meters to look for food and is followed. On the way down, a number of unusual creatures are witnessed, such as transparent squid and jellies, whose photophores give pulsating displays of colour. In such dark places, both being able to see (or sense movement) and the means of quick concealment are equally desirable. To that end, some use bioluminescence as a means of detecting food or evading predators. A descent to the very bottom of the ocean — some 4,000 metres — reveals life even at such cold temperatures, much of it new to science. It is dominated by echinoderms that sweep the sea bed; however, there are occasional large hunters, such as chimaera. In addition, sixgill sharks can grow up to eight metres in length and have remained unchanged for 150 million years. They are described as "living fossils" and relatively little is known about them. As the continental slope flattens out it joins the abyssal plain, which can form huge trenches. At seven miles, the deepest is the Mariana trench, and fish have been found there right down to the very bottom. Attenborough remarks that more is known about the surface of the moon. Species captured on film for the first time include the Dumbo octopus and the hairy anglerfish. This episode was nominated for two Emmy Award for oustanding sound editing and outstanding sound mixing in the non-fiction category. It was also nominanted for a BAFTA TV award for Best Innovation.

Headline Tag: Animals Rating: Amazing Hits: 378 Comments: 0 The Blue Planet: Frozen Seas The Blue Planet: Frozen Seas Originally broadcast October 3, 2001, this episode compares oceanic life in the Arctic and Antarctica. RT 48:39. The winter in these regions brings temperatures of minus 50°C and frozen seas that create the biggest challenge. However, there are polynyas in the Arctic, which are free of ice owing to the pressure of currents on either side, and such places do provide refuge for some species, like the walrus and the bowhead whale. A pod of belugas is shown: their movements are limited to a single hole in the ice — therefore putting them at risk of attack from polar bears. Everything changes with the arrival of summer, when melting ice brings a variety of migratory visitors. At the other end of the planet, in the Antarctic, winter is even more harsh, but emperor penguins and Weddell seals stay throughout. Under the sea ice, krill shrink in size and revert to their juvenile form in order to save energy. Chinstrap penguins overwinter to the north, beyond the ice, but return during the spring to breed. Having managed to get ashore, they have to walk a great distance to find a nest site, and the most favoured is Zavodovski Island, an active volcano whose warmth keeps ice from forming. Further south, as the icebergs break up, humpback and minke whales appear, their target the abundant krill. The leopard seal is the Antarctic's top predator. It is most effective underwater, and emperor penguins propel themselves at speed through its territory. Nonetheless, it almost invariably makes a kill.
