Formation of Brinicle Caught on Video

From Fox News:
Filmed for the first time, the icy “finger of death” is an unprecedented look at nature’s beauty -- seen at its devastating worst.

Called a brinicle (or brine icicle), cameramen Hugh Miller and Doug Anderson used a time-lapse camera to capture this awe-inspiring event beneath the Antarctic ice shelf for the upcoming Discovery Channel special series, Frozen Planet.

This magnificent yet terrifying phenomenon is caused by brine, or naturally occurring salt water, which tends to be denser than the surrounding seawater and has a lower freezing point. When super cold brine trickles down, the warmer seawater surrounds the cyclone with a brittle layer of ice.
