Brinicle formation filmed

...With timelapse cameras, specialists recorded salt water being excluded from the sea ice and sinking.

The temperature of this sinking brine, which was well below 0C, caused the water to freeze in an icy sheath around it.

Where the so-called "brinicle" met the sea bed, a web of ice formed that froze everything it touched, including sea urchins and starfish.
...

...The icy phenomenon is caused by cold, sinking brine, which is more dense than the rest of the sea water. It forms a brinicle as it contacts warmer water below the surface....

Check out the time lapse video.  Pretty cool.

And a bit creepy--like the hand of death reaching down from above.
