The icy colder finger of death

I just can’t wait until the BBC series Frozen Planet airs here in the states. Take this clip for example, which the BBC released today. It shows a “brinicle”, which is a sort of underwater icicle that forms under sea ice in winter. As the surface ice freezes, it preferentially takes up fresh water, leaving the salt behind in a dense, supercold brine that sinks through the water column. The plume of sinking brine freezes the surrounding seawater, creating a sort of tube of sea ice extending down to the bottom. Look at how it spreads out along the bottom, trapping sluggish benthic invertebrates that get caught in its path. Its one of the more amazing bits of footage I’ve seen. Why in FSM’s name would you watch Glee when there’s stuff like this happening in the real world?
