Here’s an amazing piece of footage showing the growth of an underwater icicle, or brinicle, as it reaches down to the bottom of the ocean in Antartica.
As you can see in the video, the strong brine from the sea ice above sinks, killing and entombing sea life in its path as it reaches the ocean floor. The brine is more dense than the surrounding sea water and forms the brinicle, or “finger of death”, as it makes contact with the warmer water below the surface.
The incredible footage was shot by cameramen Hugh Miller and Doug Anderson,Â with time-lapse cameras for the BBC’s Frozen Planet documentary series.Â The location of the shoot was beneath the ice near the foothills of Mount Erebus in Antartica. Brrrr.
Can’t wait to see the rest of the series!
