A very cool video of an “icicle of death” was filmed with time-lapse camera in the freezing waters of the deep. This phenomenon has never been filmed before and the BBC has just filmed one of the most amazing shots ever recorded.
In the video, we can appreciate as the icy finger forms. It grows slows but when it touches down on the ocean floor, as it entombs whatever life-form that happens to be in its path.
The “icicle of death” 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.
