HOHHOT, Jan. 16 (Xinhua) -- Authorities in northern China's Inner Mongolia Autonomous Region have dubbed popular documentary series "The Blue Planet" into Mongolian in an effort to enrich local language resources.

Local authorities said the dubbed series will be included in an exhibition in the Inner Mongolia Science and Technology Museum at the regional capital and will be offered free to all visitors. The film will also be available in other local museums in the region.

"The Blue Planet" is a British nature documentary series created and produced by the British Broadcasting Company (BBC). It took four years to complete and premiered in 2001 in the United Kingdom.

Narrated by David Attenborough, "The Blue Planet" dives deep into the Earth's marine environment.
