This clip is the perfect example of the beautiful cinematography of BBC One and the famous narration of David Attenborough, showcasing this phenomenon for the first time.

When ice sheets form on our oceans, the seawater is ripped apart and separated into brine and freshwater ice. This process of separation creates a release of the saltier brine water down into the water column because the brine is heavier than the sea water. As this plume of brine sinks, the surrounding seawater is frozen and a tube-like piece of ice creeps down with the sinking of brine. This conduit of ice then creeps towards creatures roaming the sea floor and traps any slow-moving animals in its path. It's one of the most amazing time-lapsed footage ever recorded!

The seven part Frozen Planet series showcasing our wonderful planet through its most harsh season, winter, will soon be airing in the States for all our viewing pleasure!
